Black RTV, they don't even stock diff gaskets at my local Checker

blue rtv and the seal from pepboys. Just did my front and rear cuz they were both leaking when I bought it

 

[79k20350]

RightStuff gasket maker... Best stuff I have ever used

Blue RTV, never had good luck with the black stuff, seems to be real picky about moving the part and it breaks down kind of fast.

 

[badfish4tail]

black rtv

I use red rtv, dont know why, I like the bling red line

 

[Jagged]

Black RTV

 

[scrappy88]

The Right Stuff gasket maker. I used black RTV but had too many problems with leaks, even when I used a ton of it. The Right Stuff is expensive but well worth it IMO.

Gasket and black RTV.

any tips on using the RVT? how wide a strip, how do you work it around the bolt holes....

sorry for the noob questions, but thats what we're here for right

dont worry about the bolt holes and i put a 1/2 inch bead all the way around then worked it with my finger so it was spread even and i wait 5 min before installing the cover to let it kinda tack up

I run a generous bead of red RTV on the diff cover. Make sure to go around the holes. If you see sealer pushing out around the cover after its installed then you know its good and covered.

just don't use the grey stuff like i did......had to destroy the cover to get it off.

for another basis of comparison, i use the grey on the 3rd members in my Zuk. to get them to break loose, i have to jack the TRUCK up by the third member.
