WEll, essentially you remove the yoke and replace the seal. The issue, however, is that there is a ONE TIME USE crush sleeve that needs to be replaced, between the two pinion bearings. Then the yoke is retorqued to a specified tightness, crushing the sleeve and everything works. If you do not replace the crush sleeve, you will be too tight on the bearings when you retorque, causing bearing failure.

How much will it cost to repair a GMC 2003 Sierra 1500 V6 Differential Seal that leaks? I live in Michigan

It is very easy to replace either the pinion seal or the cover gasket. To replace the pinion seal, remove the driveshaft and let it hang ( it shouldn't come out of the tranny). Remove the pinion nut and the pinion yolk ( may have to tap it with a hammer). With a screwdriver and hammer remove the seal,,then wipe the seal area clean. Take new seal and tap in with hammer and replace yolk and drive shaft.

There are several things to consider, first I would check the tire balance. Then I would go to the front alignment. If you have trouble on one side or the other you may just have a bad tire.

Yes what is the torque spec for the nut on the rear diff yoke?

Hi, there is no real torque spec., as the pinion gets tightened against a crush collar, creating a preload for the pinion, as the preload is tightened to 20-25 lbin, on a rotational measurement, the nut torques itself. This measurement can only be measured with the ring gear, and center section out of the housing. This may sound confusing, but this is how a typical setup would work. If you are replacing the seal, because of a leak, you could remove the flange, replace the seal reinstall the flange, snug it up, untill it is seated, then give it a small amount of tightening. You should not over tighten this nut, as it could result in pinion bearing damage. If you use caution, you can do this without an issue, Good luck...Coop

Only way I know of to do it correctly is to remove the carrier and change the pinion crush collar and re set pinion depth to match ring gear. I've seen some people just tighten it up and "let it fly" but it's not really the correct way to do this. I usually "cheat" and count turns as I remove the nut, then just go a tiny bit further and leave it there. But you are past that already.

Replace rear axel bearing on 4x4 5.3 Litre gas engine

Loosen differential cover and let oil drain. Remove cover, remove U lock from axel. Pull axel out. Remove bearing seal then bearing. Install new bearing, seal and reinstall axel. Reinstall U lock and new cover gasket. Fill with 75-90wt gear oil. Now I know that sound pretty straight forward. But there are some things to remember. The U lock can be difficult to remove sometimes. The most important thing is the seal, you will need to make sure it gets seated correctly and not torn when installing axel.
