Following up on an earlier post, it occured to me (after extensive searching) that the reason my differential is chattering is probably because no friction modifier was added when the axles were removed to put in the longer studs (I don't know this for a fact, but I bet I'm right). I know it was added after the original install, because I was charged for it. The timing also coincides with when the noise started. So I've decided to drain the differential and add new fluid with FM.
My question - the counter guy at NAPA told me to use a gasket to seal the housing. I bought a Victor Reinz gasket on his advice. Now in searching a few threads, I see most people use black RTV. Can I still use the gasket without any leaking problems (filling with Valvoline 80w90 non-synthetic), or should I go with the RTV? Also, does anybody know torque specs for the housing bolts (I'm a chronic over-tightener)?
Thanks for your help, and happy new year!
