RE: little help with the rear end

I'm sure someone will say there is a torque spec, but whats inportant is the pattern that you tighten them in. Be sure to tighter in a star pattern cause that cover is weak and flexible, so you dont want to bend it. You need 4 oz of additive. It comes from the factory with silicon, but the kit i got came with a gasket so thats what i used, i think you would be safe either way.

RE: little help with the rear end

I just used silicon and it works fine.. I word of advice on filling it though would be to take off the driver side rear tire and get a long flexable hose or funnel so you can just stick it in the whole and fill it in your fender well or out side ofthe car... its a pain in the A$$ to get that little bottle in there other wise.
