How have you used the Locking Rear Differential button in your vehicle? How do you want to use it?!?!? Thanks for watching and have a great day! Jeff
Toyotajeff in Raleigh so you can use this is the snow while driving to work?
Antonio Cognato Hi Antonio! No not the locking rear diff. You can only use this at 5mph or lower in bad conditions when your wheels are slipping.
Thank you Jeff.
May I ask a question?
Please answer my question below if possible.
My car is a Landcruiser with Hi/Lo four wheel engagement and a differential locker switch available. When use the Lo four wheel, sometimes I engage the Diff locker, I press and turn right one time or two, it shows red diff lock on the screen, obviously one front and one back never the same time. My question is I get confused which one is front lock or which one is the rear lock, the one with cross in front means front locked or otherwise?
@Toyotajeff in Raleigh
I have a 2020 TACOMA TRD PRO & it's the most useless diff lock that I've ever seen, I need diff lock in high range for mud & snow, in mud you need wheel speed and momentum, which you can't get in lo range. Jeep, Ford & others work in 2 wheel drive at anytime, Toyota diff lock absolutely sucks!
Had an idea of how it worked but you cemented that knowledge. Thanks dude, great explanation.
Thank you for this Information Jeff. I appreciate all your videos!
Good videos, Jeff. I appreciate your humor. If a Toyota (or other truck) has a locking rear differential, does it also have limited slip/positraction or an open differential? If open, would that allow the wheels to spin a lot more than LSD and if so, for snow use and rain, would LSD be better/safer? Thanks.
Wow, thanks so much for the detailed and simple explanation! I'm a single-mama and wanting to buy a 4Runner soon to go camping with my kiddos' and the only time I had heard this was on My Counsin Vinnys movie😄🥰; I'm guessing I should buy one with this option just in case I need it!
Great movie reference!!!
good video! thank you for showing the basic
Why would we bother to look at the manual when we've got you? 15K subs - well done.
Thanks Hog! I’m certainly trying! 20k here I come...
@@Toyotajeff 77.5k now, congratzz
What is the user manual for?? 😁
So nicely explained.... Nice work 👍
Congratulations Jeff for getting featured in Toyota Today with Mike and his Tacoma!!
oh cool thanks Nick! I didn't know the magazine was out yet!!! Did you see it at your dealership? Jeff
Brief and very informative video
Thanks for the video. Do you know if this locking diff applies to the 2005 rav4?
Thinking about getting a used model
Thanks
hank you for the amazing video. I just got a new 98 4runner. The 4WD would engage (solid green light) but to disengage after pressing the button the green light stay solid nothing happens right away but later after driving awhile there would be a BIG bang (shakes the car) and it disengages. Any guidance on what the problem is?
Hey there, Is this a feature for an older Prerunner V6 and if so how does it compare to 4WD in snow?
Nice straight forward my man. 👍🏽
Hey Mr. ToyotaJeff CONGRATS on 15,000 SUBS👊🏼
Woop woop I’m so excited and grateful for my viewers :)
I like your explaining 👍
PERFECTLY EXPLAINED 😍💯
great video!! I had no idea wtf that button did 😆
Thanks excellent information
Good Stuff, Great Tips😃👍🏿
Thank you!!
I have a 2018 Tacoma 2x4 off road trim with Locking Differential. Trying to figure out the purpose of a 2 wheel drive, off road trim...but also the purpose of the Locking Differential on a 2 x 4.
Thank you for the video.
Does the gx470 series have a rear locking differential?
Use it frequently while I’m at the shooting range, on my way out I cross a wooden bridge and then have to drive up a 65% grade hill. If it’s snowing or muddy the diff lock is a big help,
I’ve used MTS and crawl control many times for fun there too! The hill is not plowed during winter
Actually that sounds really fun!!!
can I use this in 4-Hi, Have you ever tried ?
@@rayberger2694 not a good idea. Meant for going straight and locking the wheels together on the same axle. Deep mud or snow. Don't want to turn alot because of the back wheels are locked together.
@@ethandupit73 The locking differential will not even lock in unless it is in four wheel low, so that answered my question. Thanks anyway.
This was a damn good explanation short n sweet
I have a diff locking button on my 2004 mazda 2. Now I know what it's for. Thanks,!
Thank you!
Which trim level does this Elocker come on?
I just got a 2019 Tacoma off road. Truthfully I don't know what I'm doing. I pressed the locking rear button when in 4 high. It flashed, then went away since I wasn't in 4L. Did I do anything to harm the truck, or is the truck smarter than me? Thank you!
Thanks buddy 🥂
i used this feature in eurotruck simulator 2 every time i crashed into a curb/corner and i wanted to know how it worked in real life thankyou for the explanation
Never used it before.. but good to know. Thanks
I have a locking diff on my 2012 Tacoma PreRunner- but it’s not 4WD. Would I just put into low gear anyways? Your videos have been great and I’m learning so much!
I would like to know this aswell. Did u ever figure it out?
Use the rear lock feature often in snowy weather in Massachusetts
thanks jeff
This sounds like it's made for VERY slippery conditions where the wheels are stuck deep in very wet snow, mud, sand. And only use to get you out of a rut, not for long distances. I'm thinking "logging roads".
So having a 4×2 trd offroad tacoma does all this apply as with you cant drive over 5mph being mine is not a 4×4?
Hey Herbert also want to know.
Only engages in 4L
How is this any different ? Found on a 2014 Tacoma trd ? They re all fancy buttons that do the same
Jeff does the 2019 4runner have 4000 in hidden dealer incentives for the month of February, trying to get a nightshade and was told this by a Toyota dealer out west but I'm trying to just buy local.
Nope Matt haven’t heard of that from Toyota. Although every region is a little different. Jeff
Lol people asking you the craziest questions in the comments. Thanks for your video
I was wondering what the best setting your truck in is when you’re in a snowstorm but still able to drive 30 mph, I have a 2020 Toyota Tacoma off-road that’s a standard, I have the A-Trac button and a locking rear DEF, but are those only for 4 wheel low
You should be alright in hi-4. Locking the diff causes the rear tires to lock. Locking the diff would be good in a snowstorm but definitely turn it off when hitting some pavement or low snow amounts.
What is different from center diff lock button ..
Can i find one such like diff for kia Sportage 2002?
Or rear 2WD systems our 2004 Ford Ute has the locking differential system but I've never used it so here I am.
My work truck in an F350 and has this option but no 4wd. I turned it on and got some odd sound from the rear so i shut it off.
Jeff, do you know when the 4Runner will get Toyota safety sense?
With the new redesign. I’ve heard 2 different of my Toyota contacts say the 2020 model and the 2021 model. So not sure yet....jeff
Does 2018 tundra off road have any rear locking differential ?
@@JKHTX makes no sense tbf
Thanks.. valuable
Been using alot of land cruiser
2001
2005
2009
Xtera 2009
Fj 2010
Did numerous offroad in Dubai, Oman, kuwait, Egypt, Jordan & Saudi Arabia
And never needed that button, becoz smart ( beginners ) like myself try their best to avoid getting stuck with not equipped automobile 🚙
.
Note: Never exceeds your car limits or even come to near of it. If you are not willing to waste your time & money in the garages )
So can I drift with the locking rear diff 2WD?
Thanks men this really helped
Can you do sharp turns though? I'm pretty sure there's like clicking sounds when you turn a lot.
You can but imagine going in a circle with both tires going the same speed, left and right, just doesn't work, and you'll break stuff.
When you lock the rear differential is it OK to put your transmission in low going downhill?
Good question. Did you figure it out?
TQ
What happens if you have driven the truck in the rear diff lock mode at higher speeds like on the highway? I hope I did not damage anything...please advise!
Can't in 4 low.
if you lock the diff and began a turn your car would probably oversteer and crash lol
Man you really looks like Benny Hill!!! Hahaha amazing
How do you enable it on the RWD model... Since I don't have 4WD
Does the 2020 sr5 4runner have this?
Only on the off road, venture, and Trd pro models
How do you unlock it? The same way when it’s in drive?
So.. You can only use this in 4 lo? I would think it could be used in 4hi . someone please tell me if this is wrong.
I have a 2013 sr5 trd tacoma. I thought it had the rear locking hub but I was wrong. Welp darn still love my truck.
In my Tundra I have the auto LSD and the computer activates that when it is necessary ..in my opinion unless you don't have an auto LSD it is very unnecessary to install one
Excellent explanation!! I live just 30miles North of Greensboro, in Reidsville, NC. By chance, would you or anyone you know.....have on hand or can easily get a low mileage 3.4L engine for a , 95 T100 DX ext cab 4wd manual 5spd ? I am trying to get my T100 on the road, invested over $5k in new parts on it since 2014 and engine went out in 2017. I bet I didn't put no more than 7k miles on everything since 2014, even put new white letter 31 10.50's on it 2 days before engine went out...smh & lol. I have the worst luck! Anyway, I am in search for a T100 3.4L engine, 93-97 as far as I know. I know the T100 has the sump or deep part of oil pan at rear of engine and 4runners its in the front.....which makes a huge issue with the crossmember on the T100 (long story). I tried someone local and they want $1400 for an engine with 277k??? I just can't take that chance. Hopefully you can help or know someone that may help a struggling Toyota T100 lover get his truck on the road again? Thanks and sorry for the long message.
2019 4runner. when in 4h, rear wheels skip when making tight turn. can anyone explain the system?
yong32986 my 97 runner did too. As well as the three different gmc sierras ive owned did it as well. It’s because it’s trying to turn the tires at the same rate when it can’t. The inside tire will complete the circle before the outside tire will. Wish I could explain better. But the radius of the inside circle is smaller than the outside one but trying to complete them with the same amount of tire rotations.
It's simple really, don't use 4H while on non slippery surfaces because you can damage your drive train when making turns.
If you're turning left, the right rear wheel would have to cover more distance than the left rear wheel and when in 4h, both wheels get the same amount of torque, the left rear wheel would have to skip in order to match the speed of the right rear wheel.
It's not a problem on muddy or slippery surfaces but can damage your drive train and even ruin your transmission if you try it on concrete. 👍
Would you use this in the snow?
Use 4H when driving in snow and diff lock isn't required
Was in the rockaways beach 54 to be exact (NYC)Was barbecuing outside of a 1962 winnebago My wife's father showed up to pay a visit with a 1995 Camry. He decided to take The sand covered road. And within 40' was on able to get out. I backed up my 2011 Hyundai Santa Fe limited with the 3.5 engine. After connecting a chain to my hitch with a bicycle U lock. My all wheel drive started to dig me into a hole. My wife was screaming(she's black and maybe alitt tipsy) for me not attempt this with a Hyundai!!!!how I'm going to get stuck...
I was pretty determined to win the argument that I could get him out. After realizing that the rear wheel was spinning and I was in fact stuck, I had a lightbulb moment remembering the rear axle lock. I took a deep Breath and pressed the button the light turned green and I proceeded to move forward..... I was able to get the Camry out of the sand and of course ........WIN
Way to go!!!!!
Question Jeff. Will it break if i engage the locker at 75mph speed? I accidentally pressed it instead of the dome light. And i think it went solid red if i am not mistaken and turn it off as fast as i can. I am worried it will break. It just happened 2 hours ago. Thanks.
Same here I bumped the button accidentally but was going slow.
Wish there was a way to disable button until needed so no engaging it by mistake
The differential will only lock in 4L, well unless you have done the locker mod. I can't imagine someone going highway speed in 4L
@@moose7065 that is me, 70MPH in 4L on I25 for 2hours with Toyota 4runner after 2D malfunction.
@@jangyun6868 why would you ever drive that fast, in 4L. U looking to die? Jesus
Do I have to be in 4-LOW to use this ? can I do it in 4-Hi ??? I am thinking about my very steep drive
way after it has snowed ??? Also, Did you ever play on the that TV show the big bang theory ???
i think you cant use in 4H, since it is high speed, once you engage in diff lock max speed is 30 km/hr i have seen in some manual and some one said too.
so lets awaits others response as well
How come tundras do have diff lock like Tacoma
My rear locker doesn't seem to work. I did exactly as you said and the red light would not stop blinking.
Same here, did you found out what was happening?
Drive forward while slightly turning either way for a few feet. The splines have to line up properly for it to engage.
What about using it to do a solid burn out?…..2015 f150 3.5l ecoboost
It is my understanding that turns should NOT be attempted with the the diff lock engaged. Especially on pavement, wet or dry. Torque bindup could snap an axle and/or mabey the axle connection point in the diff.
How do i turn it off?
It went on on my father's car ( prado 2014 ) and i cant turn it off 😅
I wish Toyota would implement the rear locking differential like Ford does.....2wd, 4high, and 4low
The other day I got stuck in mud, both rear wheels were spinning I engaged the rear locker and it got me out like magic so idk why it says to use the locker only when one wheel is spinning and keep in mint my truck is 2wd
How deep was it and how did u engage it in a two wheel drive? Pls help
Me out. Did u out it in neutral before hitting it or in parked at a stop?
@@Boostloading82 it was like 8-10 inches deep both wheel were spinning. I just left it on drive and clicked rear lock button and waited a few seconds for it to engage and I stepped on gas very slowly and it came out like it was 4wd
What happens when the lock real diff is continuously flashing?
What does center dif lock do?
It splits power 50/50 on each axle, so i.e. if your front wheels loose traction, rear wheels will still have power to pull you out. Locking center diff should be used only on slippery surface or on uneven terrain like when offroading, and never on a dry pavement. But unlike the rear diff lock, you can go faster than 8km/h.
@@MrHombreloco does 4L lock the center diff automatically on the Tacoma?
2wd for city in summer and 4wd in rain
What would happen if you left the locking differential on at higher speeds 55 60mph
your vehicle handling ability will decrease more so at curving road surfaces. the work of the differential is to allow each wheel to spin at different speeds at a corner. typically, the outer wheel in a corner spins more.
@@danbmwmba you forgot to add snapping axles
Great video. Thanks for the information. Very educational.
Mate, are you sure it's a good idea to use lock differential when turning on asphalt...?
Maybe you should power-on it off road... and do not turn "too much" also :))
Exactly what I was thinking, I always read to never use it on dry asphalt..
@@MrRedHotChiliMan yeah, only if he cranking turns, it didn't look like much of a turn tbh
My Prado V6 comes with all time 4WD
Why the abs light turns on?
In slippery surfaces, traction control and ABS brakes are the worst things to have. If you know how to drive then you shouldn't need them and they are actually doing more harm than good. With the locking diff you are never going fast and ABS brakes just get in the way.
@@Tuckersteward aaah that's why
When only at 4H, the operation is by limited slip.
If you have atrac, why would you use this instead?
The locker only ensures that both sides spin with the same speed. It absolutely does not imply equal distribution of power. Speed and power and different physical quantities and cannot be mixed.
Diff lock takes very long time to engage on my Toyota fortuner
Might have to roll it back and forth
Drive forward a few feet while slightly turning either way. The splines have to line up properly for it to engage
Locking rear diff button is for blowing up the puny 8.2 rear diff
It's good for really bad weather
Yes at low speeds under 5mph when your wheel is spinning
@@Toyotajeff haven't had any bad weather so far. I might've jinxed myself. Lol
You forgot to show how to disengages it . I accidentally engaged it and had trouble disengaging it . There must be a trick or an easy way to do it .
I tryed just pushing button to disengage but didn’t work.
I had to turn off engine and on a few time , shift to neutral a few times before it disengaged. Anyone know an easier way ?
I do know in my 4th gen 4runner that I have to switch into 4hi and 4lo that I have to put the car in neutral first, I believe it works the same way going into and out of diff lock, hope this helps!
i also felt the same, and then i switch of engine and restart, then it (difflock light)went off
Did you figure out a procedure for disengaging?
Thank you haha ! I thought my new truck was broken lol
Just read all this, confused. I bought a 2017 Tacoma TRD OffRoad, no 4WD but has the Lock Dif button. For what if it's not 4WD?
Because having a locking rear is still useful in 2wd when one wheel is slipping.
Side by side CanAm with ac/heat
Hahaha I had to look this up , the car salesman told me this was traction control....
He saw.you coming a mile away
Hi
Hi
I use it to get unstuck in large snow drifts or 4 wheeling when necessary. I will not buy a truck or SUV with out it. I will never buy a open diff again.
That's just the button you always have to turn back off after somebody else drives your car. lol I always wonder what all these soccer moms who bought the older 100-series Land Cruiser did when they saw a SECOND GEAR SHIFTER!!! *gasp*
I've been thinking the same thing.
Lol
That button doesn't make it TRD does it? Say on a 2nd Gen 2011.
And make sure you disengage before you get back on the hwy !
So basically drift mode
