just make sure the diff cover is clean and oil free before you apply the RTV...

Oh and having warm oil helps speed up the process

Wow this is a lot tougher than I thought it would be. It been about a half hour since I started and I’ve only got 3 bolts lose. The ones up top are gona suck. This is going to take a lot of beer.

Jack up the rear and put jack stands under the unibody then let the rear axle drop completely exposing the diff cover,makes a world of difference and will get more of the gear oil out also.

Ain't thread lock fun(Argh)

Don't give in to the shops (even though I may be a mechanic who suffers when people DIY)! Remain part of the ever-shrinking group of people that ACTUALLY work on their own heeps :)

You should work out a bit more. :D

The hardest part of changing my diff fluid was putting on the RTV.

you guys are right. At least I won't have to do it for another 30,000 miles :D

Or 15,000... Which weight did you use?

I'm gonna do the same this weekend, but I don't plan to use RTV... I've bought a Lubelocker gasket...

I'll comment after... wish me luck :D

I also skipped the RTV and used gaskets(FelPro) instead, so far so good. Just have to make sure to clean up the surfaces well.

Tell me how that works out...

I've got one of the lubelocker gaskets that I won in a raffle, and haven't used it. Thought about just keeping it as a spare because I usually use RTV instead. (dunno)

My lubelocker seems to still be working fine after 4 months.

If you're going to use the Lubelocker gasket, ignore their torque specs. It will just break your bolts and make a medium simple job into a PITA.

If you stick with the stock grade 5 bolts torque to 17-20 ft-lbs, and if you replace them with grade 8 bolts (6 marks on head, get them cheap at tractor supply co) then torque to 25 ft-lbs. The lubelocker gasket says 35 and is just too darn big for bolts that size.

If you want to get the bolts ahead of time, get 5/16-18 grade 8 bolts, 3/4" long, plus lock washers. If using an aftermarket diff cover, get 7/8" long bolts or cut down 1" bolts by 1/8".
