Sounds delightful. Too much electronic tech nowadays, and that’s coming from a 20 year old who’s pissed at all my vehicles for having electrical problems! What I wouldn’t give to just operate everything mechanically...
I had to make a 30 minute drive in three inches of snow at 5:30 🕠 this morning and was happy as could be when I pulled the shifter on my 2002 Tacoma 4x4 and it went right into gear ⚙️ I don’t have lock out hubs but it sure did feel good when it went in gear.
Just did this and it worked. Thanks, man! Before fixing it, the 4wd light just kept blinking on any selection. I drove like that for a few days then it started going on and off randomly lol. Decided to fix it. Now when I switch to 4x4 it engages and disengages flawlessly. Thanks again, man! 🇵🇭
Mine stoped working last week after off-road fishing trip. Toyota stealership here in N.Vancouver couldn't find the problem for 2 days, so i took it home before they charge me crazy money for new actuator or God knows what alse. Watched your video and just finished work on it. It is working nice again, no problem so far! Very helpfull video, you've saved me $$$ and time! Thanks man!
I hope this helps someone that reads this! I have a 2014 tacoma. I got in it and it was stuck in 4 wheel drive and I had not used my 4 wheel drive in over a week. I was almost sure this was the issue. After checking the plugs and wires and the vacuum line and all were fine. I decided to take my actuator out and check it. The motor worked fine when I hooked it up to the 12 volts. So I pit it all back together and thought about everything and thought I'd have to take it to toyota. Then I decided to check the switch in the dash and that was the issue. It wasn't bad it had just come unplugged somehow. Maybe when I had my stereo installed they didn't get it clipped all the way. So this is an option. If you try to pit your truck in 4 low improperly and it doesn't make the beeping noise or your 4 wheel drive lights are not flashing! Check the plug on your switch!!!!! Again I hope this helps someone!
I wanted to thank you for this awesome video. I followed your very detailed instructions and was able to fix my 4WD too. For less than $30 of fluid and lubricants I was able to avoid paying the "stealership" over $1000 for this repair. Thanks for creating and sharing this!
In Process - started this project and will let you know if it works once the gasket material dries and I add fluid. Here is what I learned. (1) a short (3") rachet makes taking out the upper bolt on the passenger size a breeze. (2) The screws holding the actuator together were severely corroded and almost impossible to remove with a screwdriver, I live in MI. (Thank you vice grips.) The screws can be replaced with 5mm x .80 pitch, 16 mm in length cap screws.
Just wanted to say thanks and let you know this video is still helping people out! I just got my Taco back into 4WD for the first time in a while thanks to you!
I always watch your videos when I have to fix my 08 tacoma lol. So now I'm having the same problem and now I'm here on your TH-cam channel learning alot from you😁🤙🏾💯 thank you so much and keep it up. Guys like me don't have a ton of money and guys like you help us alot by doing your TH-cam videos. Thank you again 💯🤙🏾
I had this exact issue on my 2006 2.7L Tacoma. This worked! I used Permatex “the right stuff 90 min gasket maker” so I didn’t gave to wait 24 hours and now my 4x4 works like it’s supposed to. Thanks for the video!
I finally got my 4wd actuator fixed, Thanks for the video . The hardest part was getting that upper Right bolt back in, needed a fine tooth ratchet to get enough turn on the bolt to move it. I think mine was locked up when I took it apart the motor would not turn by hand but turned ok with power put to it. So I put some oil on the motor to free it up and soldered the leads and it works great now. Thanks Karl.
This fixed my 08'. The 4th bolt on the actuator is nearly impossible to get to. Luckily, it was only finger tight, so it went back on finger tight! Great instruction, and thank you.
Awesome very well detailed tutorial! I was able to fix my 07 Tacoma with this video. If it helps any one I made a mistake and move the gears which slightly misaligned the fork when I put it all together my Tacoma was detecting an error. This solution was just to reset Gears into 2 wheel drive position and it was good to go!
How did you reset the gears? Is there a procedure to relearn it or did you have to take it apart and reposition them? Thanks, having an issue with my tundra after driving through a 3 foot deep puddle
This is so informative thanks so much! Im repairing my own tacoma I bought wrecked but now that I'm almost done with it I have noticed mine has the same problem,. I put it in 4HI and 4LO and the lights just blink without engaging 4wd. I think there is a TSB on this for the second gen tacomas so ill give it a try and change my ADD Actuator. Once again thanks for this awesome vid!
I'm not great with liquid gasket and might have the neighborhood mechanic do this one. How many hours "should" this take, given that there's no unexpected other issues? Thanks, great video!
Thanks, nice work. I purchased a new 09 Tacoma LB DC 4x4 now with 192,000 miles. I think I will start doing my own maintenance my auto repair shop charging too much now. For example, they replace the belt & tensioner for $700!! & they didn't replace those 2 idler pullies.
Excellent work and video. What did I learn? Not to do it myself but rather, take it to a friend that knows what he's doing and has the tools and knowledge to get it done. My smug "I can install a new battery myself intellect" initially overruled common sense.
Another front differential actuator fixed 2004 toyota 4runner 4.0 exactly the same. The only thing id suggest is taking the two 22mm bolts out that supports the differential it made getting to the top bolts on the actuator easy to remove and install.
Hi. Got a 2008 (second gen) toyota tacoma 4wd V6. Problem was 4x4 was intermittent (especially in wet weather) and unreliable going from 2wd to 4wd. Did that for about a couple years but then all of a sudden it's stuck in 4wd. Read all the posts about the front ADD actuator and I assumed that was it. Took the actuator off and inspected it. Very clean inside, tested the motor and it works, soldered the connectors anyway, and put back together correctly. Next, went to the Transfer Case actuator. Saw the vent tube was broken and I suspected moisture. tried tapping the actuator lightly with a rubber mallet and the plastic now 13 year old vent hose nipple broke off. So, I removed the actuator and immediately saw the problem. Water inside, very badly corroded terminals, so basically a bad actuator beyond repair. Ordered a new actuator for about $250 off amazon. My question is this: How do I orient the transfer case shift axle to reinstall the new actuator? I believe the new actuator comes in the 2WD position (the gears inside). My old actuator was in 4WD position when taken off and the shaft was in 4wd since it was locked in 4wd. The front add is locked into 4WD. Should I take apart the new actuator and turn the gears to the 4WD position and then the new actuator will be in the same position as the old one? Or do I try to push the axle into the TC to the 2wd position (all the way in) and install the new actuator? Also, there's about 5/16" of play on the shaft. How do you make sure the shaft is positioned correctly when you put the new actuator on? Watched and read a lot and can't quite find the answer. Thanks for any input!
with the 4wd actuator: You can just reinstall as is. Set your dial to 2H and unplug the battery. The computer goes through a routine to make sure that the system is in 2H prior to doing anything else. with the transfer case actuator: I would recommend just reusing the old shaft axle. I haven't messed with the transfer case actuator but I believe that shaft axle requires the whole transfer case to be disassembled in order to be removed
I have the same problem on my 05 Tacoma, can hear the drive shaft kick in but no 4wd. Great video Want to try this before I get a new part but have to wait for the weather to get a little warmer only 15 degree here.
Thanks so much for this video! Just bought an 09 taco which is having issues with the 4wd light blinking/not engaging properly. Just tried this fix, gotta wait my 24 hours before I fill it up and see if it works but fingers crossed 🤞
My FJ Cruiser actuator dont want to engage on 4H, dealer suggested to replace it for C$790, ouch! I will probably attempt to fix it the way you did, I never off road so probably it just seized up or need soldering, hopefully nothing major, thanks for the suggestion!
Thanks for the video! I think I have this same problem on a 2008 Tundra. Flashing 4wheel drive light/no engagement. What steps did you take to check if the A.D.D. was the issue? I don't want to go tearing into my truck just to find out that was not the issue.
I have this same problem. Strange thing is, if i plug and leave a code scanner plugged in the 4wd lights stop blinking and it goes into 4wd no problem. If the scanner is not plugged in obd port the 4wd dashlight is lit up and it wont engage.
Been there ,done that but….I never found the bad connection even thru I checked with a meter 3 times. Some how on the 4th try I found the bad connection. However this was months after the fault occurred so that by that time I had bought a new one for over 800 ca dollars. Now I have a spare for my 2 year newer truck. What caused the melted solder connection was making a 90 deg turn on pavement with my boat in tow. Just took it out of the water. Lesson learned; never take a truck out or put in 4x4 while making turns.
My 2001 Tacoma got stuck on 4-wheel drive, what I did was disconnect the electrical connector and it disengage, do you think my problem is the actuator? it goes back to 4 X 4 when I connect the electrical back. Appreciate your help
My 05 is having a similar issue. When i select 4 HI it locks the wheels and the truck will not move. Is the remedy for mine or am i experiencing something different? Thank you for your time.
Is this what I need to do? I have a 2006 Tacoma and here are the symptoms: 1. 4WD High and low will not engage, and there is no noise when i try to engage. 2. At all times when im driving the green 4WD light is blinking This began after I went down a very bumpy forest road in 2WD. Nothing out of the ordinary happened, but the next time I wanted to go into 4WD it wouldn't engage. wanted to get other's opinions before I take it apart.
Can you show a picture of what you mean? When I reinstall I am not sure if I should put the forks in the groove on the end of the 4wd shaft or on the smaller longer cylindrical portion.
Hello I followed your instructions but when I started my car, the 4w drive is still not working and it keeps blinking. What can you suggest I should do? Do I replace the whole unit?
Hello I bought the replacement unit from Amazon but when I installed it but the lights is still blinking and not engage. I also bought the switch 4 wheel drive replacement from toyota company but nothing change. What do you suggest I should do? Thank you for your time.
I would suggest inspecting the wiring to see if you have any tears on the cables. Also use some contact cleaner on the harnesses to make sure you have proper electrical connection. Are you also rolling the truck forward slowly when you're activating the 4WD? Do you have automatic or manual transmission?
@@KFloTacoma hello I did everything that you instructed. I clean the cables with the contact cleaner and replaced the vacuum hole. I have an automatic transmission. My model is tacoma 2007 V6 transmission. But when I started my car the lights still blinking. Thank you for your time.
I’m having the same issue, when you turned the switch to engage 4x4, would it make any noise? If I turn the switch there is no noise from the transfer case or the front diff. If it was the front actuator wouldn’t the transfer case still try to lock?
I believe the transfer case spins the front drive shaft all the time. the 4wd actuator engages/disengages the front diff to lock onto the spinning front drive shaft
Have you found any option to purchase the pre-cut gasket for this? I would rather pull, fix and replace all in one go instead of having to wait 24hrs for the gasket material to cure.
KFlo's Tacoma Build yup! Used permeated right stuff 1-minute gasket. Just gotta reassemble in 5 mins. 😂 I did and only torqued the 3 easy ones in 5 mins... and took my time for the 4th one.
iggychloe i torqued the 3 i could reach to meet the 5 min timeline. The 4th legit took me close to 20 mins to install and tighten the 4th. It’s like Toyota doesn’t want you tightening it. That said, thinking about it... raising the truck from the frame rather than using ramps or from the axle should give you more room.
KFlo, thanks for putting this video together! I was able to fix my 4x4 problem by following your instructions. My problem wasn't related to the contacts coming loose on the motor, however... it was because there was a bunch of water in the actuator! After draining and drying it out the best I could, everything went back together and works great now! One question... do you know how to seal the actuator up so water doesn't get in it again?
KFlo's Tacoma Build I have a 2014 Tacoma and it’s stuck in 4x4 I tried resetting it and driving back and forth to see if it it goes back to 2wd but it doesn’t you think I will have to do this or a other issue
i would advise to remove the connector and use a contact cleaner on the metal contact points first. It may just be a connection issue. If that doesn't work, then you can pull it off and take it apart per this video
KFlo's Tacoma Build I want to try this because I think mine may be a connection issue since it seems to be driving normal however it’s not going into 4WD now
KFlo's Tacoma Build thanks man just did pulled it off and took it apart and just put it back together and it’s still stuck in 4x4 any thoughts on what my issue may be thanks 👍🏽
Did you test it with the 12v power source like what i did in the video? Also, sometimes the dielectric grease inside the housing that is used for the position sensor ( its the metal semicircular strip, prevents clean electrical contact. Clean that off and test it out while its off of the truck prior to reassembly
I tested the actuator that same way you did using the battery charger and it was sparking and the motor was not spinning, what might this be? Thank yoh
Hi,my 2006 tacoma 4wd only engage when the truck is turned off, then when i turn it on the 4wd stay on and can go to 2wd but cant go back in 4wd until i turn the truck off, do you know if this video will repair this ? Thanks!
The video will repair this. It sounds like the position sensor is not making good contact. On the reassembly, just clean up all of the grease on the underside of the plastic housing as well as the fork that glides against it. Don't use any grease on those specific contact points and you should be good to go
I got a question..? I had my 4wheel drive go out after 150k miles so I did a test to see if I could fix the original one after watching your video and it worked perfect simply needed a lil bit of solder on the connectors and it fixed the old one instantly. Soo after I fixed the old one I took it out threw it away and soldered the new one I bought straight out the box to try and bullet proof the bitch. Truck runs great but I’m curious why every time I shift into 4wheel drive it has a rather loud clunking sound.?
Mine also clunks once in a while going in and out of 4wd. You may just need to cycle it on and off all the way to 4Lo in order to wear in the actuator a system.
My 08 tacoma wont go into 4wd. Just flashes the green 4wd symbol on dash and I can hear clicking in the glove box, which I assume is the ACU. I also checked the front drive shaft that runs from the transfer case to the front diff. when I engage the 4wd and hear the clicks the front drive shaft locks up. If im not mistaken this should mean that the ecu and transfer case are both operating correctly and that would point all fingers to the actuator right? Would love your opinion
Did you hear whether or not the transfer case was clicking? It's at the rear of the transmission at the rear end of the front drive shaft. What may be happening is that the transfer case and the front actuator may not be syncing up
It means that it could be locking from either the transfer case or the front wheel drive actuator. Both have to lock together for the 4wd to work. If one is locked and the other is not, the drive shaft can still lock into place.
I just finished reassembling the actuator, changed front diff fluid, now I had new problems. Tried the 4hi, it’s now stuck in 4wd and 4wd lo blinking. I found leak in the actuator. I must have not installed it properly. Back to drawing board again.
You would have to make sure that the adjustment forks are in between the collars during reassemble. Did you test the electric motor before hand before closing up? Make sure the contact prongs are also clean btw. The dielectric grease has a tendency of preventing good electrical contact so clean that off too before reassembly
Yes I did check the motor and it’s working fine just like the way you tested yours with 12V battery. I am going to disassemble the transfer case this time and set it to neutral. Hopefully it’ll turn it back to 2wd. Don’t want to drive in 4LO going to work. That’s my last resort, if still won’t work I’ll take it to the auto shop.
@Beaf supreme I found out that the vacuum rubber tubing that’s connected to the transfer case actuator is broken. I cut it to where it fits back tightly. I went ahead and disassembled and cleaned the transfer case actuator anyway and found little water inside. Part of the contacts are already corroded but I cleaned it good and put it back together.. Should Ive known that problem, I would’ve touched the front diff actuator. After disassembling the front diff actuator and transfer case actuator, it still stucked in 4wd. So I manually disengaged it. I’m back to 2wd but the 4wd light still blinking. ECU might be confused.
Thanks for the video! I think it has been asked already so my apologies, but wasn't sure on the answer. When I switch it to 4Hi I can hear a motor spinning in what I think is the actuator, but could be the transfer case I guess? Is this how yours was? If I hear a motor spinning does that mean that the connection is just fine? Just want to make sure we were in a similar boat before tackling this thing tomorrow.
@@KFloTacoma Got it. So if I can hear the actuator motor turning when trying to engage but it won't switch into 4hi, would you still recommend trying your repair or would that be a different problem? Thanks for getting back to me quickly!
okay. I ask because i'm currently looking at one but we couldn't get it to engage the first few times of trying. we took it back to the dealer and they had it engage right away. from then on we managed to get it to engage much easier. just wondering if this would be from it sitting for a month or two or if its foreshadowing problems down the road.
My truck won’t engage 4wd, the light just flashes. I took apart the actuator and beefed up the connections to the motor, greased the gears and I also tested the motor with 12v and it worked, I put it back together and it still won’t go into 4wd. Any thoughts?
So I still can’t get 4wd to engage. I can here the motor run in the transfer case actuator running when I switch it to 4wd, but I can’t here or feel anything in the front diff actuator. Do you know the sequence of operation?
You can watch my front regear video for the actual torque specs. I want to say they're 10-15 ft-lb from the top of my head. Thanks for watching and supporting the channel!
Unfortunately I don't have that technical information on hand. I would recommend pulling one of the bolts out and checking it against a thread gauge. It's sealed with RTV so pulling it out (to take measurements) and then putting it back until you get the parts should be fine.
Went to do this, and cant get the 4th bolt buried on the passenger side. Which ratchet are you using? I either cant get the head on the bolt or cant get it to swing through the space. Very tight and annoying.
@@KFloTacoma Finally got it off! How did you get all corroded screws out of the actuator? Sprayed with penetrating oil overnight, wire brushed, picked and tried several screw drivers & vice grips with no luck. Dremel to cut the heads off? Or maybe just a new unit.
I used needle nose vise grips and clamped down on the really stubborn screws. If it's too seized, then you can defintitely find a rellacement unit on amazon for relatively chea0
I did soldier the actuator motor I put everything on. now just waiting for the 24hour to refill the oil. Can I try switch on the 4x4 to see if it work or do I have to wait till I fill it up?? I really want to see if it works🤔
After waiting 24hrs I finally tried it and it works a little better. From 2wheel to 4hi works great but from 4hi to 4low the lights start flashing again and my truck got stuck on 4x4. I had to drive it around turn off the truck multiple times to get it out of 4x4. Some reason it only does it when I use 4low🤔🤦
Did you use contact cleaner to clean the surfaces of the metal contacts in the connector? Did you make sure that when you reinstalled the actuator, the forks of the actuator are between the shoulders of the collar?
Great video, but I made a big mistake today... I watched videos, read the Chiltons book (which said NOTHING) and when I finally got it out, I tore into it only to screw myself. I have an 03, it is supposed to be vacuum operated, it's not... It's an electric worm gear, and when I took it out and it came apart, I lost my location of the worm wheel. I tried to figure it out by logic, and there are no markings to line things up. But, if I'm off a tooth I won't have full engagement and may strip splines, so I gave up... I am now waiting on a new front diff actuator; Yup, I suck and I'm pissed off that I couldn't get things right. I just can't find the right video or book, I'm gonna order a shop manual...
Does it internally look the same as mine? If it does, there is a position sensor and as long as you reassemble it properly And reinstall it properly, you should be Ok.
Thanks so much for the video. I posted this question on TW, but haven't seen a response yet...hoping to tackle this issue tomorrow before winter sets in any further: I am new to Toyota and just purchased a 2010 Tacoma V6 this spring. Now that we have snow where I live I've discovered this problem. I'm going to attempt this fix tomorrow, but wanted to see if anyone has input on one thing I've noticed. When I turn to 4hi I get the flashing dash lights, they don't go away when switched back to 2hi, but do when engine is turned off. HOWEVER, I noticed that when they ARE flashing that I can hear a strange sound when pulling away from a stop. It's hard to describe the sound, but it almost sounds like rubber slipping (if that makes sense to anyone). Also hard to tell where the sound is coming from, but from the drivers seat it sounds like it could be below and behind me, not up near the engine. Any input would be fantastic and very much appreciated. Thanks!!
That may be the actuator attempting to engage but is not fully engaging. If it doesn't engage then the light blinks to show an error. When you turn off the car and then turn the 4wd knob to off and then start the car back up, it will reset the 4wd back to 2wd. Usually it requires the truck to start rolling prior to fully disengaging, which is probably the noise you are hearing. Once you try this fix, it will make a sliding / hammering sound whenever the 4wd engages and disengages. Once fully engaged, the lights will stop flashing.
That sound is what I hear when 4lo is engaged, like a rubber grip sound behind you. It might be that you are in 4lo and dash isn't relaying that correctly. If this fix doesn't work, check 4wd sensor
That's the 90% fix that many Tacoma Owners went with on Tacoma world. Also, the actuator in the front is for the 4wd (front wheel) engagement, the actuator at the rear is for switching from 4Hi to 4Lo
Hi i have a toyota hilux 2006 4x4 my front diff dont want to lock i have the same ass you i wacht this video and try do it but it dosnt show anyting on the dash the motor works and everting but nothing the only thing is that the smal hose of the actuator wa.broke nothing more i dont have a actuator on my tranfercase ,, it did the same as you flashing first on the dash then nothing pls lett me know what more can i inspect so a i can fix it thank you
That hose is actually a breather hose. The actuator may have taken on water and fried the motor. Take it apart and replace it. A new actuator is about $150. It's better to replace the thing at this point but if you have the time and the tools, then you can go ahead and try to perform this fix
Need HELP. Once I connected with the socket to the actuator just to test, it works perfectly on the truck. But once I put it back in place it gives me 2w to 4w failure.
@@KFloTacoma I did. Then it shows 2w to 4w fail. Then I take it off and leave it connected with socket it works. But as soon as I put it in it doesn't. I'll order new part and see.
If you have the front of your truck on jack stands, you should be able to move that collar back and forth by hand. Here's a video of what that assembly looks like when it's fully taken apart (Skip to 2:25): th-cam.com/video/JhCUFpXiQXM/w-d-xo.html&ab_channel=KFloTacoma You can align the splines by moving one of the tires by a few degrees and moving that collar back and forth - you're trying to mesh the teeth essentially. There should be no resistance when you move that collar back, unless there's something seizing up on the assembly
@KFlo Tacoma no resistance at all. It moves smoothly. That's why it was confusing me because when I plug in the socket to test, it works perfectly fine, as soon as I put it in place, it don't even try to move to 4wheel, start up the car and the alarm comes up not even trying to go to 4 wheel. So I order a new part, hopefully that helps.
This makes me realize how much I loved my 90 Toyota 4X4. Manual four wheel drive lever, manual locking hubs, lever activated blend doors. Good stuff!
Sounds delightful. Too much electronic tech nowadays, and that’s coming from a 20 year old who’s pissed at all my vehicles for having electrical problems! What I wouldn’t give to just operate everything mechanically...
Same i love my 99 Tacoma manual everything the only thing electrical in the interior is the radio lol
My 92 was the best. Even the 4 cyl Eng.
I had to make a 30 minute drive in three inches of snow at 5:30 🕠 this morning and was happy as could be when I pulled the shifter on my 2002 Tacoma 4x4 and it went right into gear ⚙️ I don’t have lock out hubs but it sure did feel good when it went in gear.
Just did this and it worked. Thanks, man!
Before fixing it, the 4wd light just kept blinking on any selection. I drove like that for a few days then it started going on and off randomly lol. Decided to fix it. Now when I switch to 4x4 it engages and disengages flawlessly. Thanks again, man! 🇵🇭
Glad it helped! thanks for watching and supporting the channel! 🇵🇭

I have a 2014 tacoma. I got in it and it was stuck in 4 wheel drive and I had not used my 4 wheel drive in over a week. I was almost sure this was the issue. After checking the plugs and wires and the vacuum line and all were fine. I decided to take my actuator out and check it. The motor worked fine when I hooked it up to the 12 volts. So I pit it all back together and thought about everything and thought I'd have to take it to toyota. Then I decided to check the switch in the dash and that was the issue.

Again I hope this helps someone!
I wanted to thank you for this awesome video. I followed your very detailed instructions and was able to fix my 4WD too. For less than $30 of fluid and lubricants I was able to avoid paying the "stealership" over $1000 for this repair. Thanks for creating and sharing this!
+Donald Chaplin I'm glad that it helped!
Brother, thank you for this video. My '05 Taco got stuck in 4Lo. Dealership wanted $4,600 to replace the actuator!!
I just got quoted today for $4000 including the actuators...dealerships are a fucking rip off
In Process - started this project and will let you know if it works once the gasket material dries and I add fluid. Here is what I learned. (1) a short (3") rachet makes taking out the upper bolt on the passenger size a breeze. (2) The screws holding the actuator together were severely corroded and almost impossible to remove with a screwdriver, I live in MI. (Thank you vice grips.) The screws can be replaced with 5mm x .80 pitch, 16 mm in length cap screws.
Did your gasket seal?
You're my hero. My 2006 Taco has been "stuck" for quite some time. Ok, wish me luck. I'm going in!
Good luck brother!
I get stuck in tacos all the time
@hondafan163 😂
TSG any luck? My 2006 just started doing this.
Make sure before anything the fill plug will come out first . Thanks for the video I learned a lot .
Good tip!
Rambo Ollie what is the full plug?
@@DirtBikes_MathGarden Fill plug. So you can make sure you can fill the differential back up once you are done with the fix.
Great video, you got right to the repair, without 20 minutes of fluff that I saw on the others that I tried to learn from.

I had this exact issue on my 2006 2.7L Tacoma.
This worked!
I used Permatex “the right stuff 90 min gasket maker” so I didn’t gave to wait 24 hours and now my 4x4 works like it’s supposed to.
Thanks for the video!
Good stuff! thanks for supporting the channel!
I finally got my 4wd actuator fixed, Thanks for the video . The hardest part was getting that upper Right bolt back in, needed a fine tooth ratchet to get enough turn on the bolt to move it. I think mine was locked up when I took it apart the motor would not turn by hand but turned ok with power put to it. So I put some oil on the motor to free it up and soldered the leads and it works great now. Thanks Karl.
+D21403 yea that one bolt is quite deep in there. I'm glad my instructions helped!
This fixed my 08'. The 4th bolt on the actuator is nearly impossible to get to. Luckily, it was only finger tight, so it went back on finger tight! Great instruction, and thank you.
Glad it helped! thanks for watching and supporting the channel!
Beautiful work! Had trouble getting into 4hi today, but finally went on the 6th time. I'll be back here soon doing this same repair. Thanks man!
Cool good luck dude. It's a pretty easy fix
Watching your videos makes me wish you would purchase a 3rd gen Tacoma.. youtube is really short on good diy videos. Thanks for your hard work
Thanks for the kind words! Fortunately, many of the work I post on this channel can be translated to the 3rd gen
Awesome very well detailed tutorial! I was able to fix my 07 Tacoma with this video. If it helps any one I made a mistake and move the gears which slightly misaligned the fork when I put it all together my Tacoma was detecting an error. This solution was just to reset Gears into 2 wheel drive position and it was good to go!
How did you reset the gears? Is there a procedure to relearn it or did you have to take it apart and reposition them? Thanks, having an issue with my tundra after driving through a 3 foot deep puddle
Tim Hulmes I’m curious about the question you asked, that was a good question... unfortunately no response
This is so informative thanks so much! Im repairing my own tacoma I bought wrecked but now that I'm almost done with it I have noticed mine has the same problem,. I put it in 4HI and 4LO and the lights just blink without engaging 4wd. I think there is a TSB on this for the second gen tacomas so ill give it a try and change my ADD Actuator. Once again thanks for this awesome vid!
Did it work?
I'm not great with liquid gasket and might have the neighborhood mechanic do this one. How many hours "should" this take, given that there's no unexpected other issues? Thanks, great video!
It should take about 1-2 hours
Thanks for the great video. I thought it was hopeless until I watched this. Mine was a pain getting back into place but once installed it worked!!
Glad it helped! Please help my channel by sharing my vids with your tacoma friends!
Thanks, nice work. I purchased a new 09 Tacoma LB DC 4x4 now with 192,000 miles. I think I will start doing my own maintenance my auto repair shop charging too much now. For example, they replace the belt & tensioner for $700!! & they didn't replace those 2 idler pullies.
Saw this on TW. Thanks for you time and effort. Good job.
Excellent work and video. What did I learn? Not to do it myself but rather, take it to a friend that knows what he's doing and has the tools and knowledge to get it done. My smug "I can install a new battery myself intellect" initially overruled common sense.
Another front differential actuator fixed 2004 toyota 4runner 4.0 exactly the same. The only thing id suggest is taking the two 22mm bolts out that supports the differential it made getting to the top bolts on the actuator easy to remove and install.
That's a great idea. Thanks for the input
Wow, probably the best how-to video I have ever seen, thank you so much,,
Hi. Got a 2008 (second gen) toyota tacoma 4wd V6. Problem was 4x4 was intermittent (especially in wet weather) and unreliable going from 2wd to 4wd. Did that for about a couple years but then all of a sudden it's stuck in 4wd. Read all the posts about the front ADD actuator and I assumed that was it. Took the actuator off and inspected it. Very clean inside, tested the motor and it works, soldered the connectors anyway, and put back together correctly.
Next, went to the Transfer Case actuator. Saw the vent tube was broken and I suspected moisture. tried tapping the actuator lightly with a rubber mallet and the plastic now 13 year old vent hose nipple broke off. So, I removed the actuator and immediately saw the problem. Water inside, very badly corroded terminals, so basically a bad actuator beyond repair. Ordered a new actuator for about $250 off amazon.
My question is this: How do I orient the transfer case shift axle to reinstall the new actuator? I believe the new actuator comes in the 2WD position (the gears inside). My old actuator was in 4WD position when taken off and the shaft was in 4wd since it was locked in 4wd. The front add is locked into 4WD. Should I take apart the new actuator and turn the gears to the 4WD position and then the new actuator will be in the same position as the old one? Or do I try to push the axle into the TC to the 2wd position (all the way in) and install the new actuator? Also, there's about 5/16" of play on the shaft. How do you make sure the shaft is positioned correctly when you put the new actuator on? Watched and read a lot and can't quite find the answer. Thanks for any input!
with the 4wd actuator: You can just reinstall as is. Set your dial to 2H and unplug the battery. The computer goes through a routine to make sure that the system is in 2H prior to doing anything else.
with the transfer case actuator: I would recommend just reusing the old shaft axle. I haven't messed with the transfer case actuator but I believe that shaft axle requires the whole transfer case to be disassembled in order to be removed
Great video man. A shop just quoted my friend 3k for this...lol, um, no... FYI for your video watchers, a new Dorman replacement assembly is only $200
I'm glad you liked the vid! Thats a great idea to go with a Dorman replacement.
I have the same problem on my 05 Tacoma, can hear the drive shaft kick in but no 4wd. Great video Want to try this before I get a new part but have to wait for the weather to get a little warmer only 15 degree here.
Yea, I hear you. It's been way to cold here in Jersey to do any outside mechanical work
Did you ever give this a try? If so, did it work? Thanks
I'm having the same issue. Wondering if I should just replace it as a whole
These actuators are now cheap enough, I would recommend replacing it as a whole
What torque did you put on the bolts once you put the actuator back on? Thanks this was a great video! 👍
Thanks so much for this video! Just bought an 09 taco which is having issues with the 4wd light blinking/not engaging properly. Just tried this fix, gotta wait my 24 hours before I fill it up and see if it works but fingers crossed 🤞
Best of luck bro!
It worked perfectly! Thank you so much, saved me a bunch of money and time
Good stuff dude, glad to hear! thanks for watching and supporting the channel!
What are the torque specs for the add?
My FJ Cruiser actuator dont want to engage on 4H, dealer suggested to replace it for C$790, ouch! I will probably attempt to fix it the way you did, I never off road so probably it just seized up or need soldering, hopefully nothing major, thanks for the suggestion!
I think you can also find the full actuator on amazon, go to my page under driveline upgrades (amazon.kflo-krib.com)
Thanks for the video! I think I have this same problem on a 2008 Tundra. Flashing 4wheel drive light/no engagement. What steps did you take to check if the A.D.D. was the issue? I don't want to go tearing into my truck just to find out that was not the issue.
thanks! i was hoping it was something I could handle on my own. Well made, easy to follow video.
Wicked video.. I did everything you described in the video. And problem ended up being the plug in wire connection
I have this same problem. Strange thing is, if i plug and leave a code scanner plugged in the 4wd lights stop blinking and it goes into 4wd no problem. If the scanner is not plugged in obd port the 4wd dashlight is lit up and it wont engage.
Thanks for the video great when searching for a couple weeks can you tell me where that air breather line terminates how high up on the engine
This video is very helpfull, i did that yesterday and i fixed the car thank you👏👏👏
I'm glad it helped!
Been there ,done that but….I never found the bad connection even thru I checked with a meter 3 times. Some how on the 4th try I found the bad connection. However this was months after the fault occurred so that by that time I had bought a new one for over 800 ca dollars. Now I have a spare for my 2 year newer truck. What caused the melted solder connection was making a 90 deg turn on pavement with my boat in tow. Just took it out of the water. Lesson learned; never take a truck out or put in 4x4 while making turns.
My 2001 Tacoma got stuck on 4-wheel drive, what I did was disconnect the electrical connector and it disengage, do you think my problem is the actuator? it goes back to 4 X 4 when I connect the electrical back. Appreciate your help
My 05 is having a similar issue. When i select 4 HI it locks the wheels and the truck will not move. Is the remedy for mine or am i experiencing something different? Thank you for your time.
Was there any light on the dash when this happened to you??? I have no lights on dash
I think water getting into mine through breather? Is the breather necessary really? Thinking about sealing it off
awesome vid . appreciate the details on postion of bots and what to expect. thx
I'm glad you like the vids. Please share my vids with your tacoma friends and help my channel grow!
Is this what I need to do? I have a 2006 Tacoma and here are the symptoms:
1. 4WD High and low will not engage, and there is no noise when i try to engage.
2. At all times when im driving the green 4WD light is blinking
This began after I went down a very bumpy forest road in 2WD. Nothing out of the ordinary happened, but the next time I wanted to go into 4WD it wouldn't engage.
wanted to get other's opinions before I take it apart.
I would recommend cleaning the electrical contracts on the harness first. If that doesn't work, then take it apart and perform my fix
@@KFloTacoma not really "your" fix.... it's been around for awhile...lol ;)
Same happen to my car hilux
What about putting back on the vacuum hose
@6:45 I do mention it. I just never showed it on camera. Also, fun fact - this is my first ever video in this channel
After you torqued down the actuator, can you move the truck and wait 24 hours before filling differential fluid?
how far are you moving it?
Fixed mine today! Thank you for the video!
Guys, Make sure that when you reinstall the actuator, that the fork is in the center of the pulley that slides up and down the shaft!
KFlo's Tacoma Build what size of tires do you have in your trunk?
Can you show a picture of what you mean? When I reinstall I am not sure if I should put the forks in the groove on the end of the 4wd shaft or on the smaller longer cylindrical portion.
After the hand tight hour wait, what torque spec should be applied?
Are you supposed to drain the fluid before you fill it up or can I fill it as is ? Thanks for the video
If maintenance isn't due yet, then you can just top it off.
Great video!! Thanks for posting it!😀👍
Hello I followed your instructions but when I started my car, the 4w drive is still not working and it keeps blinking. What can you suggest I should do? Do I replace the whole unit?
Yea, it's fairly cheap. I have the part link pinned in the top comment of this video
Hello I bought the replacement unit from Amazon but when I installed it but the lights is still blinking and not engage. I also bought the switch 4 wheel drive replacement from toyota company but nothing change. What do you suggest I should do? Thank you for your time.
I would suggest inspecting the wiring to see if you have any tears on the cables. Also use some contact cleaner on the harnesses to make sure you have proper electrical connection. Are you also rolling the truck forward slowly when you're activating the 4WD? Do you have automatic or manual transmission?
@@KFloTacoma hello I did everything that you instructed. I clean the cables with the contact cleaner and replaced the vacuum hole. I have an automatic transmission. My model is tacoma 2007 V6 transmission. But when I started my car the lights still blinking. Thank you for your time.
Thank u so much for your video and the time u put into it.
I really appreciate it
Glad it was helpful! Thanks for watching and supporting the chnnel!
I’m having the same issue, when you turned the switch to engage 4x4, would it make any noise? If I turn the switch there is no noise from the transfer case or the front diff. If it was the front actuator wouldn’t the transfer case still try to lock?
I believe the transfer case spins the front drive shaft all the time. the 4wd actuator engages/disengages the front diff to lock onto the spinning front drive shaft
Excellent! Good instructions and "how to" video.
Have you found any option to purchase the pre-cut gasket for this? I would rather pull, fix and replace all in one go instead of having to wait 24hrs for the gasket material to cure.
No precut gasket. There are some high temp and high oil RTVs that don't require 24 hours to cure and you can use those as a substitute
KFlo's Tacoma Build yup! Used permeated right stuff 1-minute gasket. Just gotta reassemble in 5 mins. 😂
I did and only torqued the 3 easy ones in 5 mins... and took my time for the 4th one.
Sweet! Good stuff!
@Dave and @KFlo’s any special way to torque down that 4th bolt (passenger-top)?
iggychloe i torqued the 3 i could reach to meet the 5 min timeline. The 4th legit took me close to 20 mins to install and tighten the 4th. It’s like Toyota doesn’t want you tightening it.
That said, thinking about it... raising the truck from the frame rather than using ramps or from the axle should give you more room.
KFlo, thanks for putting this video together! I was able to fix my 4x4 problem by following your instructions. My problem wasn't related to the contacts coming loose on the motor, however... it was because there was a bunch of water in the actuator! After draining and drying it out the best I could, everything went back together and works great now! One question... do you know how to seal the actuator up so water doesn't get in it again?
I would use RTV, the same one on my amazon page. Amazon.kflo-krib.com
KFlo's Tacoma Build I have a 2014 Tacoma and it’s stuck in 4x4 I tried resetting it and driving back and forth to see if it it goes back to 2wd but it doesn’t you think I will have to do this or a other issue
i would advise to remove the connector and use a contact cleaner on the metal contact points first. It may just be a connection issue. If that doesn't work, then you can pull it off and take it apart per this video
KFlo's Tacoma Build I want to try this because I think mine may be a connection issue since it seems to be driving normal however it’s not going into 4WD now
KFlo's Tacoma Build thanks man just did pulled it off and took it apart and just put it back together and it’s still stuck in 4x4 any thoughts on what my issue may be thanks 👍🏽
Did you test it with the 12v power source like what i did in the video? Also, sometimes the dielectric grease inside the housing that is used for the position sensor ( its the metal semicircular strip, prevents clean electrical contact. Clean that off and test it out while its off of the truck prior to reassembly
I tested the actuator that same way you did using the battery charger and it was sparking and the motor was not spinning, what might this be? Thank yoh
You'll have to replace the whole thing
Hi,my 2006 tacoma 4wd only engage when the truck is turned off, then when i turn it on the 4wd stay on and can go to 2wd but cant go back in 4wd until i turn the truck off, do you know if this video will repair this ? Thanks!
The video will repair this. It sounds like the position sensor is not making good contact. On the reassembly, just clean up all of the grease on the underside of the plastic housing as well as the fork that glides against it. Don't use any grease on those specific contact points and you should be good to go
I got a question..? I had my 4wheel drive go out after 150k miles so I did a test to see if I could fix the original one after watching your video and it worked perfect simply needed a lil bit of solder on the connectors and it fixed the old one instantly. Soo after I fixed the old one I took it out threw it away and soldered the new one I bought straight out the box to try and bullet proof the bitch. Truck runs great but I’m curious why every time I shift into 4wheel drive it has a rather loud clunking sound.?
You have fresh fluids in the front diff right? Does it clunk when you take it of 4wd?
Yep all new fluids, it’s a quiet clunk going in a a loud one going out
Mine also clunks once in a while going in and out of 4wd. You may just need to cycle it on and off all the way to 4Lo in order to wear in the actuator a system.
My 08 tacoma wont go into 4wd. Just flashes the green 4wd symbol on dash and I can hear clicking in the glove box, which I assume is the ACU. I also checked the front drive shaft that runs from the transfer case to the front diff. when I engage the 4wd and hear the clicks the front drive shaft locks up. If im not mistaken this should mean that the ecu and transfer case are both operating correctly and that would point all fingers to the actuator right? Would love your opinion
Did you hear whether or not the transfer case was clicking? It's at the rear of the transmission at the rear end of the front drive shaft. What may be happening is that the transfer case and the front actuator may not be syncing up
@@KFloTacoma I havent looked at that, but if the front driveshaft is locking into place wouldnt that mean that its working?
and by "it" I mean the transfer case
It means that it could be locking from either the transfer case or the front wheel drive actuator. Both have to lock together for the 4wd to work. If one is locked and the other is not, the drive shaft can still lock into place.
KFlo Tacoma so your saying that it could be the actuator on the transfer case instead of the actuator on the front differential
The plastic housing for the motor and gears, can you add some silicone seal to make it water tight?
It should be water tight, there is a rubber o-ring that goes around the housing.
I just finished reassembling the actuator, changed front diff fluid, now I had new problems. Tried the 4hi, it’s now stuck in 4wd and 4wd lo blinking. I found leak in the actuator. I must have not installed it properly. Back to drawing board again.
You would have to make sure that the adjustment forks are in between the collars during reassemble. Did you test the electric motor before hand before closing up? Make sure the contact prongs are also clean btw. The dielectric grease has a tendency of preventing good electrical contact so clean that off too before reassembly
Yes I did check the motor and it’s working fine just like the way you tested yours with 12V battery. I am going to disassemble the transfer case this time and set it to neutral. Hopefully it’ll turn it back to 2wd. Don’t want to drive in 4LO going to work. That’s my last resort, if still won’t work I’ll take it to the auto shop.
@Beaf supreme I found out that the vacuum rubber tubing that’s connected to the transfer case actuator is broken. I cut it to where it fits back tightly. I went ahead and disassembled and cleaned the transfer case actuator anyway and found little water inside. Part of the contacts are already corroded but I cleaned it good and put it back together.. Should Ive known that problem, I would’ve touched the front diff actuator. After disassembling the front diff actuator and transfer case actuator, it still stucked in 4wd. So I manually disengaged it. I’m back to 2wd but the 4wd light still blinking. ECU might be confused.
Thanks for the video! I think it has been asked already so my apologies, but wasn't sure on the answer. When I switch it to 4Hi I can hear a motor spinning in what I think is the actuator, but could be the transfer case I guess? Is this how yours was? If I hear a motor spinning does that mean that the connection is just fine? Just want to make sure we were in a similar boat before tackling this thing tomorrow.
The 4wd acutator is an electric motor that you can hear when it engages
The transfer case is for switching from hi to lo
@@KFloTacoma Got it. So if I can hear the actuator motor turning when trying to engage but it won't switch into 4hi, would you still recommend trying your repair or would that be a different problem? Thanks for getting back to me quickly!
The transfer case and actuator work together so I would still recommend it
@@KFloTacoma It worked!! So stoked. The hardest part was definitely getting all the bolts and screws loose. Thank you so much for the video!
My only blanks in 4lo, would that fix it?
If you roll forward a little bit, does it engage or does it stay flashing the whole time?
will the dash flash like so if you are not engaging 4hi or lo properly. or does it mean it has this problem if you see those flash?
okay. I ask because i'm currently looking at one but we couldn't get it to engage the first few times of trying. we took it back to the dealer and they had it engage right away. from then on we managed to get it to engage much easier. just wondering if this would be from it sitting for a month or two or if its foreshadowing problems down the road.
For those four bolts. What is the spec ft-lbs?
7 ft-lb (hand tight)
Great video, thanks!
My truck won’t engage 4wd, the light just flashes. I took apart the actuator and beefed up the connections to the motor, greased the gears and I also tested the motor with 12v and it worked, I put it back together and it still won’t go into 4wd. Any thoughts?
I would suggest cleaning the terminals of the connectors with some electronic contact cleaner. Then reconnect and test
@@KFloTacoma cool, I’ll give that a try when I get home today. Right on for getting back to me.
So I still can’t get 4wd to engage. I can here the motor run in the transfer case actuator running when I switch it to 4wd, but I can’t here or feel anything in the front diff actuator. Do you know the sequence of operation?
Thanks for the help! Got it fixed
Glad it helped! Thanks for watching and supporting the channel!
I did this a and fixed my 4x4,but now I got a bad vibration when you up to highway speed of 55.Whould this be causing the vibration?
Do you have a lift kit installed?
Hi what were the torque specs for the actuator bolts ? Cheers
You can watch my front regear video for the actual torque specs. I want to say they're 10-15 ft-lb from the top of my head. Thanks for watching and supporting the channel!
@@KFloTacoma Hey thanks I appreciate it , I've learned some valuable info from your channel . Cheers
Can you just pull the plastic housing off without having to pull the hole assembly? If no why not?
You can try, ther's two Philipps head screws at the top with the ~1" of clearance. It will be tough to get leverage
Just orderd a replacement acuator. What are the 4 bolt sizes?
Unfortunately I don't have that technical information on hand. I would recommend pulling one of the bolts out and checking it against a thread gauge. It's sealed with RTV so pulling it out (to take measurements) and then putting it back until you get the parts should be fine.
Which sealant did you use?
Red high heat RTV
hey where is the fill screw to replenish the gear fluid after you finish the repair? Please let me know thank you
Watch my front diff fluid replacement video in this channel
@@KFloTacoma ok simple enough thank you!!
What oil did you use to fill back the transfer case fluid?? I bought one at napa valvoline gear oil 75W-90
I use redline. Check out my front diff fluid replacement vid
@@KFloTacoma I will thank u
Great video thank you very helpful
thanks for watching and supporting the channel!
Great video and info, thanks!!!!
Went to do this, and cant get the 4th bolt buried on the passenger side. Which ratchet are you using? I either cant get the head on the bolt or cant get it to swing through the space. Very tight and annoying.
I used a 1/4" drive ratchet which is small and thin. I also have a variety of heights on the sockets and used the one that fits
@@KFloTacoma Finally got it off! How did you get all corroded screws out of the actuator? Sprayed with penetrating oil overnight, wire brushed, picked and tried several screw drivers & vice grips with no luck. Dremel to cut the heads off? Or maybe just a new unit.
I used needle nose vise grips and clamped down on the really stubborn screws. If it's too seized, then you can defintitely find a rellacement unit on amazon for relatively chea0
Dude, thanks so much for the beer fund donation! I appreciate it! I'm glad the repair worked out well for you!
I did soldier the actuator motor I put everything on. now just waiting for the 24hour to refill the oil. Can I try switch on the 4x4 to see if it work or do I have to wait till I fill it up?? I really want to see if it works🤔
I think you should be able to try it without the fluids
After waiting 24hrs I finally tried it and it works a little better. From 2wheel to 4hi works great but from 4hi to 4low the lights start flashing again and my truck got stuck on 4x4. I had to drive it around turn off the truck multiple times to get it out of 4x4. Some reason it only does it when I use 4low🤔🤦
When 4 lo flashes switch it back to 4hi. Move forward a tiny bit then try again. It has to be in neutral/park
@@KFloTacoma I replaced the actuator to a new one and it's still not working. The lights is still flashing. Do you have any advice??
Did you use contact cleaner to clean the surfaces of the metal contacts in the connector? Did you make sure that when you reinstalled the actuator, the forks of the actuator are between the shoulders of the collar?
What if you don't wait 24 hours before refilling the differential, will it pop the seal?
The seal may not set properly. My recommendation was based off of the manufacturer label.
Your Pittsburgh tools are amazing!!! Where can I get some?!
Good job!
Harbor freight
I would say that you don't need to pull the secondary clutch cylinder and then you shouldn't have to bleed the clutch
Great video, but I made a big mistake today... I watched videos, read the Chiltons book (which said NOTHING) and when I finally got it out, I tore into it only to screw myself. I have an 03, it is supposed to be vacuum operated, it's not... It's an electric worm gear, and when I took it out and it came apart, I lost my location of the worm wheel. I tried to figure it out by logic, and there are no markings to line things up. But, if I'm off a tooth I won't have full engagement and may strip splines, so I gave up... I am now waiting on a new front diff actuator; Yup, I suck and I'm pissed off that I couldn't get things right. I just can't find the right video or book, I'm gonna order a shop manual...
Does it internally look the same as mine? If it does, there is a position sensor and as long as you reassemble it properly And reinstall it properly, you should be Ok.
Be advised as it is at your own discretion though.
What about a MT 2006 4x4 tacoma, does the MT works like this?
Mine is the same generation and is also manual transmission so yours should be the same
My 2015 MT has been having trouble with the actuator intermittently. If I turn off the engine & restart it the actuator works every time. Weird huh.
Thanks so much for the video. I posted this question on TW, but haven't seen a response yet...hoping to tackle this issue tomorrow before winter sets in any further:
I am new to Toyota and just purchased a 2010 Tacoma V6 this spring.
Now that we have snow where I live I've discovered this problem.
I'm going to attempt this fix tomorrow, but wanted to see if anyone has input on one thing I've noticed.
When I turn to 4hi I get the flashing dash lights, they don't go away when switched back to 2hi, but do when engine is turned off. HOWEVER, I noticed that when they ARE flashing that I can hear a strange sound when pulling away from a stop. It's hard to describe the sound, but it almost sounds like
rubber slipping (if that makes sense to anyone). Also hard to tell where the sound is coming from, but from the drivers seat it sounds like it could be below and behind me, not up near the engine.
Any input would be fantastic and very much appreciated.
Thanks!!
That may be the actuator attempting to engage but is not fully engaging. If it doesn't engage then the light blinks to show an error. When you turn off the car and then turn the 4wd knob to off and then start the car back up, it will reset the 4wd back to 2wd. Usually it requires the truck to start rolling prior to fully disengaging, which is probably the noise you are hearing. Once you try this fix, it will make a sliding / hammering sound whenever the 4wd engages and disengages. Once fully engaged, the lights will stop flashing.
Just a note, the fork in the 4wd actuator needs to be in between the collar of the slider inside the axle. Good luck dude
BTW, if you can sub to my channel and share any of my vids with your tacoma friends, that would really help me out!
That sound is what I hear when 4lo is engaged, like a rubber grip sound behind you. It might be that you are in 4lo and dash isn't relaying that correctly. If this fix doesn't work, check 4wd sensor
I wish one will explain why he choose to fix the one in front and not the one in the back of the transfer case. And how he determines the bad one.
That's the 90% fix that many Tacoma Owners went with on Tacoma world. Also, the actuator in the front is for the 4wd (front wheel) engagement, the actuator at the rear is for switching from 4Hi to 4Lo
@@KFloTacoma Thanks man. I appreciate your answer.
Nice video!
What are the specs of the bolts for the torque wrench?
Hand tight is fine. It's really tight in there to get a torque wrench head and a low profile socket. the RTV will keep the fluid sealed in place
Hi i have a toyota hilux 2006 4x4 my front diff dont want to lock i have the same ass you i wacht this video and try do it but it dosnt show anyting on the dash the motor works and everting but nothing the only thing is that the smal hose of the actuator wa.broke nothing more i dont have a actuator on my tranfercase ,, it did the same as you flashing first on the dash then nothing pls lett me know what more can i inspect so a i can fix it thank you
That hose is actually a breather hose. The actuator may have taken on water and fried the motor. Take it apart and replace it. A new actuator is about $150. It's better to replace the thing at this point but if you have the time and the tools, then you can go ahead and try to perform this fix
I have to hilux 2006 go on 4x4 is angage but the still blinking even I off 4x4 back.what do you thing?
Your car 4x4 light blinking.what damaged this actuator?my Toyota hilux light 4x4 blinking to now
Mine just stopped working - i think it may have been from water
I just got done doing this and the light is still flashing do i need to reset it or somthing ???
No need to reset. Is it engaging? Did you try to turn the knob on to 4wd before starting the truck? If so, did you hear the actuator engaging?
Need HELP. Once I connected with the socket to the actuator just to test, it works perfectly on the truck. But once I put it back in place it gives me 2w to 4w failure.
Did you make sure to put the fork in-between the two shoulders of the flanges in the diff?
@@KFloTacoma I did. Then it shows 2w to 4w fail. Then I take it off and leave it connected with socket it works. But as soon as I put it in it doesn't. I'll order new part and see.
If you have the front of your truck on jack stands, you should be able to move that collar back and forth by hand. Here's a video of what that assembly looks like when it's fully taken apart (Skip to 2:25):

You can align the splines by moving one of the tires by a few degrees and moving that collar back and forth - you're trying to mesh the teeth essentially.
There should be no resistance when you move that collar back, unless there's something seizing up on the assembly
@KFlo Tacoma no resistance at all. It moves smoothly. That's why it was confusing me because when I plug in the socket to test, it works perfectly fine, as soon as I put it in place, it don't even try to move to 4wheel, start up the car and the alarm comes up not even trying to go to 4 wheel. So I order a new part, hopefully that helps.
Yea, good luck with that. Maybe the electric motor is not working under load? It may have some windings that burned out?
The three gears in mine won’t turn. Is this normal because I see that they turn quite easily in your video.
They should be turning. Pull them out and inspect to see if any of the teeth/bearings are broken. Clean them and then lube them up.
Will this work on a 3rd gen ?
Yes, it should as this is a common problem with the 3rd gens as well. Just make sure to reseal the housing
Why wait for 24hrs if I may ask?
The RTV Red that I used says that you have to wait 24 hours for it to fully cure before exposing it to any oils
