Awesome task for any weekend. Have fun!!

Thanks Jorge

Great to hear! Most of these Toyota differentials are the basically the same from the late 70’s to today.

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.

Just put the races in the freezer overnight and they'll sit really gentle

Thanks for that! You wouldn’t have liked today. Exhaust manifold and tune up on a Ford Econoline Van.

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.

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.

No problem!!👍🏻

Thank you!!

Thank you David.

No problem.👍

If I ever need to purchase a replacement I will likely buy the knockoff.

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

This stuff is involved as heck

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.

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.

it4dps the process will be nearly identical but the specifications may vary slightly.

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.

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.

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.

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!!👍🏼🔧

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.

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

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!

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!

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

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!

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.

That normally is only required on models with limited slip differential. Toyota places a sticker near the fill plug that will say LSD.

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.

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.

The puller is from Yukon gear and axle. here is a link amzn.to/2ShZ4cM

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.

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.

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.

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.

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.

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

@@jtg2737 ast 7200. Here is one price well on eBay if your ok with used. www.ebay.com/itm/166289077975?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=8wXTI_s-TkO&sssrc=4429486&ssuid=FaFC5sdKRTm&var=&widget_ver=artemis&media=COPY

Very similar. Some of the specs will be different but the process is the same.

$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.

$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.

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.

allent yoglawm 👍🏻👍🏻 exactly. I change the oil on most of my vehicles at 3,000 or 5,000 instead of the recommended 7500 because oil is a whole lot cheaper than an engine.

David Craft that would been awesome. I’ll try that next time. 😂

lol I'm just messing with you. but you know how it is between people that work on cars. and how someone will be serious af and make brawpapap sound and a grrrrttt grretttt sound and then someone will say "what sound did it make again" lmao. good video though. I'm doing a samurai axle and it is identical to the Toyota axles except its like 7/8 scale lol .

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👌🏻
