Gm Truck and SUV Pinion Seal Replacement

In this video I go over the steps and procedures necessary to replace the pinion seal on a GM truck or SUV. I go over the steps and procedures necessary to replace the pinion seal on a GM truck or SUV. it is very important to properly torque the pinion nut as the nut applies preload to the bearings inside the differential. Too much preload can cause premature failure of the bearings as well as two little preload. Below are links and descriptions are used in this video. Make sure to check them out. If you have any questions or comments feel free to leave something in the comment section. Thank you for watching

Nice... I always measure from the top of the nut to the end of the stud with a digital caliper as well as paint marking everything, that way i make sure I'm back on the same turn for the preload....

[@Al-ft6zc]

So, if the measurement is short do you tighten the nut till it meets that measurement while holding the yolk in place at the paint marks?

[@miguelvasquez4231]

What happens if u dont do this how to fix it if u never marked it i need help

[@miguelvasquez4231]

And also i didn’t mark because that middle bearing where u count the threads was so loose for some reason what can i do

[@ericalynnposton8661]

What did you end up doing? I'm replacing parts and wondering the ramifications of not putting everything back exactly as it was. ​@miguelvasquez4231

[@droptimus2897]

​@@ericalynnposton8661 the bearing will have too much slop or too much tension. Just wears out quicker and you will need a new pinion bearing.

This was excellent. I like to count the turns to ensure it goes back to the right place, but I like the caliper idea mentioned below for the preload. I will be donating because you saved me a lot of money!

Awesome video easy and straight to the point great job

[@gbenz6494]

Ouch, did you count the threads before you removed the nut? This is a crucial step when installing the nut back on.

[@bryangeorge9461]

I was always taught that the crush sleeve is a one time use part and needs to be replaced and preload set anytime the yoke is replaced.

[@buzztrucker]

I'm having a hell of a struggle with getting that pinion nut off. I have an impact driver 20V that I'm trying to use after getting some PB Blaster penetrating fluid on it. I even tried a breaker bar. I have a 2000 Silverado 1500 4x4 Z71 Extended Cab. Any suggestions?

I did the front diff seal on my 2000 Yukon, never marked anything. Put it back together and now it locks up when in 4WD(Can't be driven). I obviously have the pinion on wrong and probably torqued wrong. Any suggestions when in this situation? Im going to back off the nut at lest to start.

[@isaiahavinarosas8509]

Did you fix it i did the same thing bro lmk

[@djsabourin101]

It seems to have a crush shield, so I just backed it off, put the driveshaft in and very slowly moved forward in 4wd, like maybe 10 feet, which loosens it off. I then called a GM mechanic and he told me no harm done, lock tight and 100 ft/lbs torqued and do it in increments. So I did 40lbs, then, 70, then 100 and I have no balance issues and it has not backed off at all. I've had three snow storms since and have driven about 200 miles or so in 4wd without any issue. @@isaiahavinarosas8509

I just had my rear pinion seal replaced. Now I get a random metal- on- metal chirping, grinding and shuddering on the front end. Do you think its related? 2008 jeep grand cherokee 3.7 with 166,000miles There's no whirring, like a bad differential. Thanks 😊

[@joediaz87]

I got a 92 Silverado and have a bad seal But the truck was previously a friend of mine who just passed away and I took everything off and didn't know about aligning that bolt but he got stuck and rope got into that seal and damaged it, I don't know if I'm doing any of this correctly and don't have any help. I don't know what 2 do and don't have money for a mechanic

[@joediaz87]

I pulled cloth , hard plastic, metal circle spring and some rubber gasket on the differential part, is that a bad thing or is that part of the pinion seal???

[@krisa8023]

Can you remove the bearing that is right behind the seal?

Pinion shaft has to come out first

[@Iatolaazzahola]

Not that it matters one bit, but you're off a spline on reinstall. You did forget to mention how important it is to measure the depth of the nut on the pinion threads before you take the flange(yoke) off. The yoke must be all the way back in the same position that it was in when you removed it. There is no way of knowing this unless you count the threads showing or measure the depth with a precision measuring device such as a caliper or a depth mic. Also, one other tip. I always use a flange holding tool when I remove the nut and reinstall it. I don't like banging gears together when it is entirely not necessary.

[@ronaldjones8406]

Great video.

[@HummerH-mo4cs]

Great job with the video thank you. Is the pinion nut a crush nut and should you use a new one every time you take it off ?? if so there is no mark on it to replace the same as you took it off ???

[@NeverEnoughPyro40]

First of all there’s no such thing as a crush nut, It is a crush washer which is much different than a pinion nut!

[@jonnysprojects6549]

If the yoke on the back axle spins without resistance what would i need to be replacing...would it be gears or bearings forgive me im new to this 👍

[@Dbeaves2493]

Open the diff cover and see what broke

[@charleswittmer]

All seals fail from age or just wear from high mileage.

[@alexpasillas3187]

Can you do this without a yolk puller?

[@NeukZ71]

Yes

[@TheMikevt]

It should be said though. Before you remove the drive shaft you should chalk your wheels, and set the e-brake.....unless it's on a hoist. But I've heard horror stories of this. The last thing you want is your truck rolling over you, in your slanted suburbia driveway!

[@zachnuketown]

Agreed but if someone doesn't already know that they have absolutely no business attempting this themselves to begin with.

Watching this after already removing the 32mm nut. Was not aware of pre load so didn't mark it with the sharpie like you did🤦‍♂️. Is there another way to ensure it's put back on correctly?

[@timcable]

yes - torque wrench

[@NeverEnoughPyro40]

You are out of your goddamn mind! Tell me where do you get the torque specs from considering each differential requires a different amount of pressure to crush the crush washer!

It’s not a normal torque spec you need an old style torque wrench and it measures the resistance of the rear end as it turns with the wheels off

[@lanajacknichols8397]

what about the seal in the yoke that pinion seal slides into ?

[@davidmatyis1732]

Thank you!

[@sticknstonesbrkbones]

I have done this 3 times to my chevy and it still leaks. I just ran across an article saying to put rtv silicon on the pinion and yoke splines as well as on the back of the washer before putting the nut on. Did you do that and not show it or what?

[@AaronHinesAuto]

No I have not done that before. But in my experience if the leak still appears you may have a bad yoke. The seal may have scored a ring around the yolk decreasing the diameter of it.

[@sticknstonesbrkbones]

@@AaronHinesAuto Yeah, I noticed a seal inside the yoke but no vids on how to replace it. It could be the yoke is bad. Today I took the yoke off and put the sealant on the splines and washer and reassembled it. Test drive went well. Then I notice it all dripping again and the yoke was wet so maybe I tried to test drive before the sealant was dry or like you said the yoke might be bad. well, thx for reply

[@route67slidin]

sticknstonesbrkbones how did you make out ?

[@sticknstonesbrkbones]

@@route67slidin I changed the yoke seal and pinion seal and it still leaks. I dont know why at this point. Maybe they keep selling me the wrong pinion seal or something.

[@promaterial]

@@sticknstonesbrkbones make sure that your vent is not clogged

[@user-mv4nt9xk4i]

The reason you mark the pinion NUT and pinion when replacing the seal is NOT to ensure you re-attach the driveshaft the same way it came apart, but to ensure when you replace the yoke and torque the nut you get the pinion bearing preload back to something close to proper values. If you didn't do that, good luck with obtaining proper pinion bearing preload. Now you'll need to pull it apart and start over with a new crush sleeve. You just turned an afternoon job into a multi-day-long thrash.

Yes. Video completely misses this part. A new pinion nut should be used, if possible. And preload should be measured with a proper torque wrench. Otherwise it will leak again or you’ll have a vibration at highway speeds

[@gptex92]

Have any other links or part numbers for the yoke puller? The link pulls up a harmonic balancer puller.

[@ronaldscott781]

It's a multi purpose puller and the link is correct. You can also use it for pulling steering wheels, flywheels, gears etc. You can't live without one of these if you do much auto work.

[@SurferJoe46]

Did your grandfather tell you that an independently balanced driveshaft would make the car shake? He's wrong. The driveshaft is balance all by itself and there's no way for you to create a vibration by clocking it to any other position. Old wive's tales die hard --- and I wish they would. As far as marking the gland nut to come back to it during reassembly --- that's wrong. You feel the companion flasnge lose slop and then it stops wobbling and then the preload on the pinion bearings increases until you can feel a slight drag on them as you rotate the flange back-n-forth. It's feel --- not drawing lines on the differential. I've done hundreds of pinion seals in my lifetime on everything from Hondas to Greyhound busses, OTR big rigs, and more and I've never used all the gimmickry you do ---
