Should i just get the same gm gasket or a better one? The original one didn't leak and i know some have problems with them leaking a tiny bit.

And im thinking all there is to it is lift the rear, block the front tires, and remove the differntial cap, does that sound about right? Any tips to a quicker and safter removal/install would be great.

If both surfaces are clean and free of old gasket material then the GM gasket will work just fine. I would hold a straight edge on the mating surface of the cover to make sure its not warped. I always use a wire wheel to clean the surface of the cover and a razor blade on the differential. Your method of attack sounds good....its a pretty easy thing to do.

I scraped mine with a razor blade on both sides. I also used a wire brush on the cover side.

Then I used plain ol' black silicone on the cover side(I real thin bead). The gasket that I used was the OEM paper type. No leaks since.


Just don't over tighten the bolts.

I make my own each time. Never any problems. Stay away from Chrome covers and you will be fine.

I was going to do a chrome cover, but it's just a waste.

I think you will be alright if you rough up the cover side with a wire brush or sand paper.


I just think they are after market crap, and are way thin.

I never use a gasket on diffs, just wire wheel both surfaces and run a bead of "right stuff" silicone.....never had one leak that way.

Looks like i'll be renting a torque wrench.

You dont need a torque wrench. Just realise that not every bolt has to be so tight that you have to strain to get it on.

Sounds good. When i tighten them, i just use a criss, cross pattern starting from the middle?

I have never worried about it.

Alrigt cool. I got everything just need to the oil. I already got the gm lubricant. I think i'll use mobil gear oil then just add the gm lubricant.

This is just as easy as doing a oil change.

I would not recommend synthetic, just because I think it will be more prone to leak.

Once everything is clean, ive always used a small bead on the cover, then the paper gasket and then another small bead of RTV to make sure i have a leakproof seal. Works every time.
