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

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!

[@JohnnysSpeedShop]

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

[@terishuler6105]

Need to count the turns when removing the nut to maintain proper preload upon reinstallation.

[@adamwest3637]

Teri Shuler Or count the threads?

[@frankdelligatti2670]

The axle problem turned out to be the kid at O’Reillys gave me the wrong bearing one right one wrong I want to say unbelievable but it’s believable it happened ha ha ha ha

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 😊

[@2411ozkr]

Buen trabajo🤔🚚💯

[@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.

[@atomicdmt8763]

excellent! NOW i can do it................

[@johnalenwork53]

Nice work BROTHER!!! Use new oil though.. 😊 Thanks 🙏

[@321homewrecker]

I got a 92 Chevy c1500 4.3 ltr v6 and my seal will not go flush with the differential I got another new 1 and it's the same, what do I do? There's and very small gap around all sides .

[@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???

[@gbenz6494]

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

[@frankdelligatti2670]

[@user-is2zd9yr8d]

You have to use wheel chocks? It will prob roll once you remove drive shaft?

[@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

[@lanajacknichols8397]

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

[@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!

[@Fix-it-too]

Since the drive shaft is balanced also, should it be marked before removal?

[@johnalenwork53]

Did this fix the problem without incident 6 months down the road?

[@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

[@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.

[@MrRightNow]

@@zachnuketown dude, i know that, but a safety reminder is a good thing to many

[@RRo-up4pg]

It doesn't hurt that bad if it's runs over the leg s

[@krisa8023]

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

[@_cadillacmiketyping...2533]

Pinion shaft has to come out first

[@frankdelligatti2670]

Should the driveshaft be disconnected and does it matter which side the axles go in

[@djsabourin101]

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

[@charleswittmer]

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

[@DTWCT]

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!

[@oscarurbina8352]

@@timcableokay but what is the torque spec if you know pls help me out

[@oscarurbina8352]

Did you find out the torque spec

[@bnorby213]

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

[@aladdincafe9699]

What happens if you dont put back the same way do you get a noise like a loud motorcycles noise!? I had my oil pan removed due to timing chain replacement by someone and when put back i started to get vibrating under my feet and noise over 80km speed please help!? Thanks

[@isaiahavinarosas8509]

This is because you did not align your stuff correctly you marked it before removing it

[@aladdincafe9699]

@@isaiahavinarosas8509 its was actually done by a mechanic! And he did mark the joints and went back again and rechecked everything and noise still only over 80 , 79km no noise!!!!!

can you use a breaker bar and 32mm socket by hand?

[@bigboytone35]

Yes that's what I used

[@alexpasillas3187]

Can you do this without a yolk puller?

[@NeukZ71]

Yes

[@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.

[@christinedotson9909]

Did you have to count the threads down to the nut or does it have to be torqued?

[@The_Real_Jammy]

both

[@atomicdmt8763]

probably a good idea to swap in a new axle bearing, right?

[@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.

[@jwill9877]

Do you know what the preload should be? And shouldnt we use a new nut? Also the tools to measure preload are very cheap on Amazon.

[@christopherhodge6154]

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

Holy Bible-Romans 10:9-10: 9 If you declare with your mouth, "Jesus is LORD," and believe in your heart that God raised him from the dead, you will be saved. 10 For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved. Romans 10:9-10 We're living in the end times. Jesus will be rapturing his church before the 7 years of Tribulation begins. He will come back after the 7 years. If you miss the rapture don't take the mark of the beast, you can't go to heaven if you do. It will be on your right hand or your head. God bless you.
