Got the front dif out because of a leak where the two half's go together. Not split yet so maybe I messed up. I've had it apart before, used red RTV. Looking for recommendations.
GM black silicone, probably made for them be Permatex. I use it on everything, never had a issue. I just make sure that the surfaces and really clean(new gunwash) and let the stuff get tacky, put it together, call it done!
