- 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!
Nice work on the video!
Great example of clear, concise information with easy visuals.
Great tutorial, straight and to the point. Thank You
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....
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?
What happens if u dont do this how to fix it if u never marked it i need help
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
Thank you. You got right to the point, and you told us what year make and model vehicle you were working on. Excellent camera and audio work. Subscribed!
Thanks. Changing mine soo. This is the exact video I needed.
Thanks for the clear and concise tutorial!
Very Helpful !
Thanks
Straight to the point. Thank you for the video !
Thank You! Detailed and to the point!
Looks easy. Thank you!!
Great work brother 👍
Excellent very informative 👌
Need to count the turns when removing the nut to maintain proper preload upon reinstallation.
Teri Shuler
Or count the threads?
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
Great video.
Liked and Subcribed. My 2019 just started to leak. I'm buying a seal puller and borrowing a air gun. Don't even want to think what the dealer would charge!! Thanks!!
Thank you!
Awesome video easy and straight to the point great job
Nice channel 👍
Buen trabajo🤔🚚💯
excellent! NOW i can do it................

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?

There's no whirring, like a bad differential.
Thanks 😊
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.
Ouch, did you count the threads before you removed the nut? This is a crucial step when installing the nut back on.
Nice work BROTHER!!!
Use new oil though.. 😊
Thanks 🙏
Redoing a 10 bolt GM rear axle everything went smooth until the passenger side axle won’t go back in it binds up or get stuck working this be
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???
what about the seal in the yoke that pinion seal slides into ?
You have to use wheel chocks? It will prob roll once you remove drive shaft?
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 .
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 ???
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!
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
Since the drive shaft is balanced also, should it be marked before removal?
Did this fix the problem without incident 6 months down the road?
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 👍
Open the diff cover and see what broke
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!
Agreed but if someone doesn't already know that they have absolutely no business attempting this themselves to begin with.
@@zachnuketown dude, i know that, but a safety reminder is a good thing to many
It doesn't hurt that bad if it's runs over the leg s
Can you remove the bearing that is right behind the seal?
Pinion shaft has to come out first
Should the driveshaft be disconnected and does it matter which side the axles go in
All seals fail from age or just wear from high mileage.
can you use a breaker bar and 32mm socket by hand?
Yes that's what I used
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?
yes - torque wrench
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!
@@timcableokay but what is the torque spec if you know pls help me out
Did you find out the torque spec
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
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.
Did you fix it i did the same thing bro lmk
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
Can you do this without a yolk puller?
Yes
Did you have to count the threads down to the nut or does it have to be torqued?
both
probably a good idea to swap in a new axle bearing, right?
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
This is because you did not align your stuff correctly you marked it before removing it
@@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!!!!!
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?
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.
@@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
sticknstonesbrkbones how did you make out ?
@@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.
@@sticknstonesbrkbones make sure that your vent is not clogged
hey there I have a leaky pinion seal but in the front differential. would technique work in the same fashion?
Yes! Same procedure
@@AaronHinesAuto nice my Denali AWD seal is leaking and I have all the tools already hopefully it wont take me to long!
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.
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
@@christopherhodge6154 I get a random metal on metal chirping and shuddering in the front end , after a rear pinion seal? Yikes..do I need to replace the old nut?

There's no whirring sound in the differential.
Thanks 😊
Have any other links or part numbers for the yoke puller? The link pulls up a harmonic balancer puller.
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.
Is the front or rear one ?
2:28 fuckin magic?
Impact gun??….so, basically take it to Mechanic shop and pay them to do the work…. what average handy viewer who’s trying to diy is going to have air compressor, impact gun and socket, etc, space & money??🤦🏾♂️🤣😭
Details on alternate tools and more efficient method (and torque tools) for precise pre-load tension would have made this a fabulous video, instead of just okay…..but thank you for at least trying…. We appreciate it.
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.
go to the carpenters videos dumbass -throws wrench at McFadden lol
but will he fix my leaky pinion seal?
WHY DOES THE SEAL FAIL ?
Seals fail from age and high mileage.
