Ok, today when i get home im going to change the front diff oil, since yesterday i noticed it looks like very light chocolate milk. Anyway, my question is, when i go to reinstall the cover w/ the new gasket, do i use some type of sealant? What kind do you recommend? Also if i have to use some, where do i put it? on both sides of the gasket? just on the cover side? just on the diff. side? Thanks y'all.
