Okay...my rear has been chattering on some turns lately, figured the LSD clutches may be a little thirsty for the additive. So I got my Amsoil guy to fix me up with their Synthetic 75w-140 Oil. Even got the Friction Modifier Additive.

There seems to be a good walk-through of the process here: Welcome to guzzle's Rear Differential Maintenance Web Page

For anyone that has done this, was there a gasket on your diff cover? I've heard no, instructions say no, but read a guide elsewhere to advises placing the sealant on the gasket also. HUH!?

Most don't use a gasket now days including this one.

 

No gasket, use good gasket sealer.

 

By gasket sealer, they mean RTV....

 

I use Permatex Ultra Black. Been using this on differential covers for years with excellent results.

Grey silicone was used from the factory. I used a felpro gasket from the auto parts store when I reinstalled mine last time because I'm impatient and hate letting rtv set up before torquing it down. No leaks yet.

 

I have heard the lube locker gaskets are a superior alternative to RTV.

 

Good time to change the cover out if rusty. That 08 finned alum one sure looks purdy!

 

Awesome. Thanks for the info...

 

Where can u get one of these? Do they make them for the front also?

 

Lot's of good sealers out there.

 

I'd start at lubelocker.com

The dana 50 has the same diff cover as the d60.

 

I think the lubelocker gaskets are reusable too. Pretty awesome if you ask me.

 

I use only permatex rtv's and like the gray for most applications. The important thing with RTV's is not to use to much. There should only be a minimal squish out when fully torqued down. Most of the time I just smear it on with my finger instead of laying a bead down. A bead is normally to excessive and lots of times doesn't give 100% coverage on the mating surfaces. Wiping on a thin layer you get the 100% coverage while using much less RTV.

Excessive squished out RTV while an eye sore on the outside is also bad for the components it is sealing up when it breaks off on the inside and starts plugging up tubes, bearings, gears and whatnot. I have seen oil pick up screens completely blocked by RTV from the oil pan gasket.

See nice uniform and minimal squish out of the RTV at full torque.
