- Rebuilding the rear differential in a 4th gen 4runner. This 2005 Toyota 4Runner Sport is a 2 wheel drive but the 4x4 version should be the same. I show how I rebuild Toyota rear differentials using specialized tools. this can be done without the tools I use but takes longer. The Toyota Tacoma should have the same 3rd member unless it has the E-locker option.

I love your welding trick! For heating up the housing wait until your wife is out shopping and use the oven in the kitchen... 😇
Just put the races in the freezer overnight and they'll sit really gentle
Im glad i found your video, my buddies been wrenching on heavy equipment, semis, dump trucks, trucks, cars, boats for 40 years or more. I told him i needed my differential bearings replaced and asked if he had the right tools to do it. He asked what tools? I said well to set the pre tension, the paste to check gear spacing the stuff i saw guys using on utube videos. He just laughed at me, said if i wasn't changing gears he didn't need the high dollar crap. He said you do it by feel if you know what your doing lol. Watched your video and i feel better about having him do it now.
Clear and Precise best how to video ever (camera work, narration, lighting,
Audio,) I’m now ready to go change out my diff centre!!!! Full of confidence👍
Awesome task for any weekend. Have fun!!
Hot tank/cold tank? I use my oven for the housing and the fridge freezer for the bearings.]
I use the hot tank on the housing and it does help. I have also seen dry ice used to cool the bearing races before install to shrink them. And a hot plate on the bearings to install on the pinion.
Excellent video. I have watched several videos in preparation for rebuilding the front diff of my ‘77 FJ40. This cleared up several questions I had. Much appreciated.
Great to hear! Most of these Toyota differentials are the basically the same from the late 70’s to today.
Definitely a job I'll pay a shop to do - I'd have to buy more tools to do this than it would cost me to pay someone to do the job!
great video and awesome instruction. i can tell you put alot of work into this video, and i certainly appreciate it. i feel much more comfortable tackling this job
So peaceful watching this.. oddly satisfying and a job very well done
What an interesting process, gotta love your welding trick.
Thank you very much for making this video. It has helped me a lot in rebuilding my 1984 SR5 4WD front axle.
Great vid. Super peaceful. I enjoyed every second this morning. Thank you for the motivation.
Awesome video. The shortcuts show your knowledge professionalism thanks!
Excellent detail and video quality. Thanks!
thank you for sharing. i will now speak to my mechanic like a pro
Great video! Thanks for sharing your expertise.
Great tutorial; you have the knack for teaching.
Thanks Jorge
Awesome.great video.. your explanations are crystal clear.
Thanks for sharing . Greetings from Curacao.
Thank you sir. That was great info.
No problem!!👍🏻
good video and hello from Australia
Great video! I'm about to install a Detroit truetrac in my 4r, is there a way to find the correct carrier bearings without having to buy an entire diff bearing/shim kit?
This was a life saver 😅
Great video! Thanks!
Amezing . really appreciate you work brother.
Thank you!!
Great video my friend, I could work with you all day long!!
Thanks for that! You wouldn’t have liked today. Exhaust manifold and tune up on a Ford Econoline Van.
Nice trick with the mig.
you are a great teacher
Thank you David.
Great video. Just curious, the bearings didnt look very pitted on the video, were they causing a humming or grinding sound?
Exelente..explicacion..muy buena herramientas..donde las puedo conseguir..gracias..
Nice and clear explanation throughout video! I will say carrier bearing preload seems quite loose imo. Once backlash is set go back and forth, or focus on ring gear side and tighten those bearing adjusters as tight as you can get them. There is a tremendous amount of torque going through the ring and pinion and deflection will happen without enough carrier bearing pre-load. It will not damage the carrier bearings by having too much preload. Well over 100 ft/lbs on the adjusters is common.
Thanks for the info! If I would have followed all the factory directions we would have checked the carrier preload. Toyota gives specs for pinion preload by itself and additional pinion preload after the carrier has been installed and adjusted. The adjusters have to be adjusted to meet the preload requirements.
great video, thanks
No problem.👍
Great video my freind
Very professional process and clear explanation! My friend has a 2004 Tacoma with 260k miles. The rear diff has some major play at the front pinion bearing.... But no leaks or bad sounds. Should I just try tightening the flange nut to reduce the slop?
Pine Hollow Auto Diagnostics excessive rotational play or up and down play? If the pinion is sloppy up and down you can try tightening up the nut but normally the bearings are worn and will start to make noise after tightening(unless someone didn’t tighten up enough in the past) If the play is rotational play then the pinion nut probably won’t help and you would have to remover the diff to adjust the carrier so the backlash is reduced.
You can get copies of the bearing tool for a lot cheaper on AMZN today.. I see this is 5 years old.. just went thru my own rebuild
If I ever need to purchase a replacement I will likely buy the knockoff.
Very nice tool by Yukon for removing the pinion bearing what model number is that tool so I can grab one should also work on 2000 3rd gens as well there are no links in the description sir
very good
wow ....big job !
hi, thanks for this great video! do you have a transfer case rebuild video for a 4th Gen 4Runner V8? Thanks.
The Pio on bearing removal tool requires the bearing outer race to be in place and you lift it off by pressing on the rollers, this way you don’t need to get under the inner race of the bearing,, this did my head I at first but that what make this tool so clever.
Muy buen video no ablo inglés pero entiendo lo que está haciendo mi gracias amigo
I rebuilt my toyota 7.5 and installed a locker back when i was in community college 2015 automotive service technology. I forgot how i did it. This video refreshed my memory. I want to change my ring and pinion gears, can i reuse the bearings that i replaced years ago? Do i need new crush sleeve and shims?
I need to replace the pinion bearing on my 03 Tacoma . Is it the same process ? Thank you !
The welding trick did the trick! I had to do it for both races because hitting the larger one from the back didn't budge and I was afraid to damage the housing. I don't see how else they come out.
This stuff is involved as heck
Thank you for posting.. This is a GREAT reference!
I'm guessing that is a non-locking open carrier that you are working on.. Do you know if the process is the same for a non-locking limited slip? Thanks for any info..
it4dps the process will be nearly identical but the specifications may vary slightly.
Very profesional and safe way to work. My respect. Please If any one has the part number for the replaced parts it would help a lot. Thanks
I like your channel I have subscribed
This vehicle looks like it lived it's life in the desert...like brand new underneath!
I just have to replace that front pinion oil seal.
Am I going to be able to get that front pinion off, w/out complete disassembly? (after removing the castle nut)
looking at your videos before I tackle replacing the 10 bolt Differential Gasket on my 08 FJ.. do you apply any sort of sealer onto the new gasket or just pop the old one out, clean the faces, new one in, and bolt it back up?
It should seal up just fine with the paper gasket but some will apply a thin coat of sealer anyways. The factory didn’t have any sealer applied on the paper gasket.
On the inner pinion bearing, would it be ok to warm it up first on this application? I install bearings on spindles at work on heavy mobile cranes and we warm the bearings to 350F and they slide right on. Wait a bit for them to slowly cool. Just wondering if these little bearings could take that. Cheers. Great video .
Great question!!! I had to do some digging to see if I could find some accurate information and learned quite a bit along the way. I found that people heat bearing to all different temps before install but I found a article from SKF that recommends a maximum of 257F or you can risk changing the metal's attributes. The article shows very large bearing but it should apply to the smaller pinion bearings as well. Here is a link www.lubsys.com/knowledge/knw_heatmnt.htm
Thanks for the question and for checking out the video👍🏻
This is a perfectly acceptable way to install bearings without a press. Throw your pinion in the freezer over night and toss the bearings in your oven at 350 degrees for 10 minutes or so. Take out frozen pinion, take bearing and slide it right in place. This can be done on the carrier as well.
The freezer part will not have as much of an effect as the heated bearings, but it works well. You can also use a heat gun to warm the bearing.
Also, you can wrap the bearings in water soaked rags, and put them in the microwave for 90 seconds.
Did you add silicone to the gasket? Also what was the torque spec on the diff bolts. TIA
Awesome work. How much will this cost?
nice info !!!
Since you got fire involved, you might as well had just cut the race out. I worked for a logger who could do stuff like that. Definitely exemplary of making it work with what you have!
I’m more likely to cut to deep with a torch and trash the housing. I mostly just beat them out with a drift and hammer.
Any gaskets etc needed??? in removing and replacing a rear end differential assembly on the fourth generation Toyota 4runner?
Hay what’s the part number for your spanner wrench it looks pretty cool
Thanks for the video! having a difficult time determining if the groan sound I'm hearing on my 2005 is from the diff or wheel bearing, brought to a couple of mechanics and they haven't been able to pinpoint. Sound does seem to emanate from the rear but I know sound can travel an can be deceiving. The sound changes at different speeds, very noticable at 50km/h and 90km/h. Attempted swerve test and seems to kind of lessen a bit when going left but hard to replicate consistently. Any other tests or suggestions on determining what is causing the sound, find it very bothersome and would like to have fixed. Thanks!
If the differential bearing are bad they will often make a different tone when acceleration and decelerating. The wheel bearings normally will change when swerving side to side but not always.
@@ThePracticalMechanic Thanks for the reply!
Excellent wonderful job satisfying
What about the "deflector"? I didn't notice you reinstalling a new one.
Great! Video do you happen to have a video of how it sounded while driving im trying to determine if I have the same issue. While I'm driving and foot on the gas is fine but when i ease off the gas (decel) its when i hear the noise (huming/rumblings)which seems to come from my rear of the runner. 2003 v8 4wd.
Efren Bautista I tried to capture it but the audio didn’t come out. Rumbling could be the ujoints or the rear end. I currently have a 1996 that needs rear end bearings and it rumbles slightly if I completely lift my foot from gas pedal but it whines if I feather the gas on and of. If I do a video on that one I will try to capture some audio of the noise.
@@ThePracticalMechanic thank you I appreciate it.. I removed the diff oil and plug and found shavings but no big chunks..
While driving would only rumble when i get off the gas
Great video! Do you think this process would be similar enough to help me do this job on my 99 4runner rear diff?
It will be almost identical. If you have one with a locking differential it requires a special bearing kit and a few different steps.
@@ThePracticalMechanic It's a RWD so I don't believe it does. Thanks for the quick reply!
Have you guys considered investing in a bearing induction heater and/or liquid nitrogen to install those bearings and races? Much faster and no potential bearing damage as opposed to cold mounting. Liquid nitrogen alone will suffice and really cheap to use
I ordered a induction hot plate but have not tried it yet. The bearing induction heaters are very expensive from what I’ve seen in the past. Many of them don’t accommodate smaller bearing as well. I have not used liquid nitrogen but I will check into it. Thanks for the tips!!👍🏼🔧
do you remember the torque specs for the third member drive line bolts axle bolts ?
omg no shims to mess around with, so cool
Makes it sooooo much easier. Unfortunately Toyota didn’t do this on the T100 and tundras. Have an awesome week and stay safe.
@@ThePracticalMechanic this is nice to know. However I am ever so slightly disappointed as I do enjoy a good shimming.
Thanks very much for the video! Got a question about the companion flange. What would happen if I use a flange with the rubber dampener (2WD) to an all time 4WD 4runner? Reason I asked is I’m just buying a 3rd member with the 2wd flange and don’t want to change the flange for fear of messing up the preload. Thanks in advance!
It should be ok either way. The two wheel drive version must have had harmonic vibrations that were absorbed by the transfer case on the 4wd and awd versions.
ThePracticalMechanic thanks very much for the quick reply!
ThePracticalMechanic hi. One more question. What sealant do you use to join the 3rd member to the main axle? I bought a gasket from Toyota but do I have to apply a sealant as well? What sealant would that be? Thanks in advance!
Radius if your using the new Toyota gasket sealer shouldn’t be needed. That make future service easier. I use Ford gray rtv sealer for my personal vehicles.
ThePracticalMechanic thanks again!
So my 2004 seal is leaking, can I just take the pinion out and replace it without replacing any parts? just gaskets? Any hints to do it quicker? Thanks in advance!!
If it is just the pinion seal you don’t need to remove the third member from the vehicle. You can service the seal buy removing the driveshaft and pinion flange. You should mark the nut so you can try and get it back to the same location when reinstalled.
Do you have the link to the removal from the truck think you said at the beginning you would post that link to that video as well
th-cam.com/video/Yb7mcEayB0I/w-d-xo.html
Thank you for your video. How much the price for all bearing
I don’t remember how much the rebuild kit for this particular one cost ($300-400 is normal for quality bearings) but parts and labor for this job typically ends up between $900-1200.
Do you add friction modifier to the rear-ended gear oil ? I just came across to ask you Toyota shops say so I helps with the chader in turns parts stores gear oil doesn't have it in the oil 🙋
That normally is only required on models with limited slip differential. Toyota places a sticker near the fill plug that will say LSD.
Nice! Subbed.
My Tacoma clunks when i put it into reverse when it's cold. Sounds like it's coming from the rear end. It doesn't clunk or hardly clunks at all if I let go of the brakes right when I put it into reverse. I took it to a shop and they suggested to take it to another shop that specializes in rear ends. I've also had a few tell me it could be U-Joints. I recorded a video under the truck and showed another mechanic and he said it looked like there was excessive backlash. Any idea what the issue is? I'd like to rebuild it myself if I knew what parts to replace or what to look for. Thanks!
Johnathan Hartzell it could be the rear end but it could be u joints as well. If you email the clip to chad@thepracticalmechanic.com I will take a look.
Responded back with some things to check.
@@ThePracticalMechanic Thanks a ton!!!!! I'll look into it
Johnathan Hartzell no problem.
Hey I replaced the rear differential and now the 4x4 takes a long time to lock ...do I need to reset the anything??
Since I disconnected the rear sensor ?
The rear diff shouldn’t affect the time it takes to engage because the rear is engaged all the time. Does it take a long time while driving down the road? While stationary? Was the gear ratio the same as the unit that was removed?
@@ThePracticalMechanic I know it takes a little long to engage but now it takes 5 times longer while driving .
The differential was from a 2004 SR5 4wd and mine is a 2005 SR5 4wd
Thanks a lot for your prompt response!!
@@ThePracticalMechanic when is on parking it engage fast
Caza Y Pesca once it engages does it feel like it binds up? Example if you have a area with pavement for 20 ft and then it switches to gravel. Put it 4wd and drive in a straight line and slowly pull onto the gravel if it feels like it’s binding up when on the pavement and then releases when you hit the gravel then the gear ratio may be incorrect. I hope that make since.
I found that I installed the wrong g ratio on my 2005 mine is .3.73 and 2004 is 3.91
Does the 3rd member need sealant for the bolt flange from the 3rd member to the axle housing I have a massive leak and I can't figure out why
From the factory there is only a thin paper gasket. If both surfaces are clean and flat the paper will seal. If there are any imperfection then RTV sealant will be required. Ultra black or ultra grey is what I use and then let the sealant dry/cure before installing new fluid.
So i'm in the process of rebuilding an 8'' e locker. I got the pre load and backlash to spec but from what i've read the carrier should add 5-7" pounds when installed on the pinion. But I still measured 10'' pounds on the pinion pre load with the carrier is installed like it measured with it off. What could be causing this?
You may need to add additional preload to carrier nuts. The manual doesn’t really explain how to adjust if the total preload is high or low. If the pinion preload is good I would add a little torque to one of the side bearings and see if it helps.
Can we get the link for the tool you use please? Great video!

Hi,why didn't you check the mesh pattern? great video
I normally don’t check them if I’m just replacing the bearings. If I can’t get a quality brand of bearing then I will check the pattern because I don’t trust the pinion depth will remain close the the original bearing. If I’m also replacing gears then I will start with the original pinion shim and then check my pattern and adjust accordingly.
@@ThePracticalMechanic thanks,I'm about to do my first gear set up,your video was helpful.
Master....
Hello! What kind of part number or brand the blue bearing puller? Thanks a lot!
The puller is from Yukon gear and axle. here is a link amzn.to/2ShZ4cM
01:15 which spanner brand did you use there please? It looks like it is of good design. Great work!
Its a tool from AST tools. it has interchangeable pins for holding camshaft gears as well.
Thank you! I tried looking for it but I did not come across anything. Do you have a part # for it please? God bless.@@ThePracticalMechanic

Do you have to put a seal between the pinion and the actual differential housing?
There is a pinion seal that is installed after the gear setup has been tested. This is normally the last step because if the pinion has to be reshimmed the seal will have to be removed.
Does anyone knows if there are any places in Palmdale CA that rebuild the rear differential.
How much this kind of job will cost? Thanks in advance!
Can i replace a pinion bearing by pulling the driveshaft out? Or do i have to tear into the whole diff?
Thanks
You would only have access to the outer pinion bearing while in the vehicle and it would be nearly impossible to remove the bearing and race without removing the assemble from the vehicle and disassembling the whole thing.
how many inch lbs to spin the pinion bearing flange according to the factory manual. Appreciated
The starting preload for the pinion alone is 5-7 in.lb for used bearings and 9-14 in.lb for new bearings and total preload for pinion and ringgear is measure pinion preload plus additional 3.5-5 in.lb
So 8.5-12 in.lb for used and 12.5-19 in.lbs for new bearings.
Can you provide links to the tools and the place you got the bearing
Here is the bearing tool. Https://amzn.to/3k3THJL

I had all my studs and bolts come out of the axles. Where can I get more?
If the studs came out of the axle housing you can just thread them back in but add a lily bit of thread locker on each one to seal the threads and keep them in place. You may want to try and remove several of the nuts from the studs and install the studs back into the housing to act as a guide for when the differential is reinstalled. Other wise you can get the stud from the dealership or most hardware and auto part suppliers.

I have a leak on my 2000 4runner rear diff right at the housing of the axle tube to the 3rd member Housing right near the bolts on the bottom and sidee and I can't seem to get it sealed what could be the problem ?
If it’s leaking where the tube goes into the housing then it may be difficult to seal.
First thing I would check is the differential vent and make sure it isn’t plugged up. It is located on the driver side top of the differential housing. It has a little metal cap that is crimped onto a metal nipple. The cap should be able to move up and down as well as spin. Dirt gets into the cap and causes the blockage. As you drive the increased pressure will make everything leak much faster.
You may have to removed the 3rd member and clean the inside and outside area of the leak and then apply sealant to both sides. Let the sealant dry overnight before putting fluid back in
Where are you located if I send my gear box differential toyota sienna 2006 awd do you can fix
Would this be a similar process for a 1994 Toyota Pickup 2.4L 4 x 4?
Very similar. Some of the specs will be different but the process is the same.
What’s the average cost for a differential rebuild for a Toyota? My 2008 Tacoma has 202k miles and it’s starting to scream in the rear and noticed ALOT of play in the rear.
$800 is average for bearing replacement,12-1500 if the gears are damaged and 1500-2000 if an ARB locker is being installed at the same time.
hey, my outer bearing ring is still moveable after tightening the screws of the bearing caps. is this normal or should this clamp the bearing ring in place?
I don’t think I’ve ever had one movable after tightening the bearing caps but normally when I tighten them down I already have some preload on the side bearings so it hold the adjuster in place. The locking tab will also prevent the adjusters from moving so Toyota must have known they could move a little bit.
@@ThePracticalMechanic thx. so there is Something wrong on mine. i can move them very easy and the bearing ring left some "grinding" marks in his seated place because it must have turned while driving. maybe there are the wrong bearings in the diff.
Any idea how much this would cost?
Any info on that sprayer you're using? Thanks!
It's from ZEP. I use it for brake parts cleaner. We have a machine that charges it with fluid and then air. It's kind of top heavy and they break easy when they fall off a tool cart. Sure-Shot has all metal ones that are tougher and less top heavy.
@@ThePracticalMechanic nice, I have used a sure shot in the past. Thanks!
What are using to clean it with in the zep durashot?
We use bulk brake parts cleaner in the zep durashot bottles.
ThePracticalMechanic awesome video btw and I’m buying the Yukon bearing remover because of this video👌🏻
I can already feel the misery of trying to do this without the proper tools. How much does it usually cost for it to be professionally rebuilt by you guys?
$800-$1200 seems to be the range for bearing replacement. If the gears are damaged it will of course be more.
At that price range get a third member already rebuilt with gears you want and maybe a locker with it too.
How much can a shop charge for a job like this?
the torque on the bearing cap is 62 ft lbs???
According the service information 63 ft-lbs
Where is your location sir , do you have a shop in San Jose California
Manuel Villanueva I am located in southern Colorado
How much did this job cost I just payed 1200 dollars 2003 4 runner
We are typically $1000 -1200 for the differential bearing replacement. There are additional parts and labor if the axle bearings and seals are replaced at the same time.
ThePracticalMechanic thanks for reply back
What are the torque specs on the housing bolts mate?
When reinstalling into the axle housing the nuts are torqued to 15 ft.lbs
ThePracticalMechanic Cheers mate. You recon I can just use a sealant maker without the paper gasket?
That’s what I typically do. I like to apply sealant and let it sit overnight before adding gear oil. This allow the sealant to cure better.
ThePracticalMechanic Righto, I’m regearing my rig and you think it’s ok to change the rear diff for now and do the front later on. It’s my daily driver. I got manual locking hubs anyways.
For people without a welder: No need to weld the race to get it out, instead cut a large washer in half to clear the deflector, set both halfs of the washer onto the race and press it out. Or just order a new deflector which is inexpensive. This is a good step by step video though
Thanks for the washer tip. I will take a look at the next one I pull apart and try it out. There are times when I don’t have access to air or a welder.
Can you please explain a bit more? I have a deflector in mine and cannot punch my races out... cheers!
