Rear Differential Pinion Seal Replacement

This is a video I made while replacing the rear differential pinion seal on a GMC truck. I did this one without removing the rear diff cover, but you can do it either way.

how much do one of these seals go for?,mine started leaking abit last night?,my trucks a 95 k1500

[roadragecustoms]

Depends where you buy it. $10.00 - $30.00.

could i use these same instructions to change the yoke itself?

[roadragecustoms]

Yes, you can.

Is the shock absorber bad too in because the up and down movement of the vehicle is not stopping.

[roadragecustoms]

The whole vehicle was rocking. The legs of the lift flex a little bit.

A couple of things I've never seen done should be pointed out to anyone who hasn't done this before; never use RTV sealant anywhere for this repair; not that it will hurt anything, but it will make a mess when the next guy has to remove the pinion seal again. I would not recommend anyone use an impact wrench for putting the pinion nut back on, a new nut should be used also. A beam type torque wrench should be used before and after to check preload on the pinion bearing however it's OK this way.

well since I am an auto tech, I guess that qualifies me as an expert on this stuff now doesn't it...

Why don't you just make your own video since you seem to be so smart?

Very good video, thanks. I was changing my rear shocks today and noticed mine is starting to leak. I'll be watching this video again before doing the repair. Thanks again! Very informative and straight to the point, very helpful too!
