My differential fluid is definetaely due. It is leaking and the cover is bent. I'm geeting a cover form the dealer, I have the fel-pro gasket, I have the RTV sealant, differential additive, and Mobil 1 gear fluid. Now how is this done? Do I put the RTV on both sides of gasket or the differential itself and cover?

if you use the gasket you dont need rtv, RTV is used as a gasket.

USE BOTH. If you just use the gasket, it will leak slowly.

it is spelled DEFINITELY
sorry, you spelled it worse than i have ever seen before

i'd use both though, on both sides of the gasket, and you should just buy an aftermarket girdle instead of waste your money on a new cover. or i bet you could just hammer it into place

I usually just use the rtv as a sort of 'glue' to keep the gasket from sliding around during the install. Put the gasket on your cover the night before and it stays exactly where you put it while you are doing the fluid change...

You forgot to capitalize I, also capitalize the first word in each sentence and you meant wasting my money right? Sorry, but if you are going to correct me, check yours first.

Gasket OR RTV. Both is a waste.
A gasket is always OK but if the cover is bent it's maybe better to use the RTV. Just let it dry at least 1 hour before filling the case.
If you use RTV put it on the diff case: on the cover you will miss the side holes and it will leak (1st hand experience).
Don't seal the side holes toward the center of the case: makes just an half circle around them (outside!). Those holes are for oil recirculation: don't close them!
Make a circle around each bolt hole.
