Axel seal help for my 62 Dodge Lancer

I looked at it pretty closely today, although it doesn’t smell bad, what’s coming out seems to be gear oil, I don’t see any evidence of a gasket under the retainer, and it looks like most of the oil is coming from there. The other end of the axle is dry, and it looks like they used permatex blue there. As you suggested I think I’ll pull the axle, clean things up, grease the bearing, replace the inner seal and gaskets. I’ll see if that solves the problem, if not I can pull it back apart and do major surgery.
Thanks for the excellent advice and detailed explanations, forums like this are fantastic, you all can’t imagine how much I appreciate your interest and help.
Thanks
Bill
