ps-replacing the whole hub is a great idea, if the cup's race is pitted...
I tried to fit some older seals on it.. but the way the right flange is, iirc... there is no purchase to rest the seal's lip. Yes the race is pitted, unfortunately a bit of surface rust developed inside on something and i didn't catch it.
