2nd Gen Non-Engine/Transmission Sealing Rear Diff

[cpeters]

Today I want to change my rear diff fluid and wondered if I need to buy new rear gasket or rtv or both? neither? Also installing fast coolers and changing fluid. What do I need to seal the fast coolers? Thanks.

The Fast Coolers (assuming you got them at Genos) come with a tube of the Mopar ATF gasket goop. For the rear diff, I just use high temp black RTV- probably the same stuff that the transmission uses. I'm sure you could use the same stuff for both.

When you pull the rear differential cover, you'll find no gasket - the factory seals them with a high temperature RTV. I used the Permatex High Temp Gray RTV available at NAPA - looks just like the factory stuff and seals great.
