hey guys. I'm changing the fluid in my rear axle for two reasons, it hasn't been done for a long time and the cover started to leak like hell. I'm using the RTV gasket maker stuff and my question is do I need to use thread locker on the bolts that hold the cover on? I wouldn't think I would need to but just want to make sure. thanks!

 

Nope.

 

Not necessary. Make sure the gasket sealer isn't blue.

 

black rtv and no thread locking, remember to use your limited slip additive if you have a lsd

 

Nope, as a matter of fact I do just about the opposite, I use a dab of diff oil on my finger spread on the threads same as you would an oil filter. I have never broken a diff bolt trying to get it out and am not about to. I've known mechanics to use anti-seize as well. It's never a bad idea to put just a dab of the lube on any bolt that is in an area that sees temperature changes and them diffs can heat up a good bit...

 

Howcome I should make sure its the black rtv? is the blue rtv not suitable? And I don't have limited slip so I'm good on the additive!

 

IDK, cause I've always bought either the red myself and I've never had a problem...
