Do I need to put a sealant on a rear differential cover gasket? I put a lock right in a few weeks ago and its the gasket is leaking now. I used just the gasket but wondered it this was one that needs sealant on it?
I never use a gasket, just RTV on rear end covers and I've never had a leak. all I do is give the RTV some time to cure before dumping in the 90W.

The last diff work I did was in my old '00 S10 with the 8.5" gear.
I used a very thin layer of orange RTV on a new gasket, before putting things back together. I used just enough to create a tacky surface, not so much that it oozed out when tightened. It never leaked on me...
