I just filled my 9" rear end on my project car a few weeks ago, and I noticed a small puddle of oil under it yesterday. It's leaking at the 3rd member connection. Is there a gasket between there that I might need to replace or something? The car doesn't run or drive yet, it's just been sitting there.

There is a gasket that goes between the third member and the housing and any auto parts store should have one, however I prefer RTV. Pull the pumpkin, clean both mating surfaces then cote the pumpkin surface with a thin layer of RTV. Reinstall the third member and tighten it down a little at a time adding a small amount to each nut, working your way around the differential. After 3 or 4 trips around it should be tight. Give it at least an hour to cure before adding fluid.

Thank you 👍

It's always a good idea to replace the copper washers on the studs.

I'll remember that 👍
