    If it is leaking from the bottom of the diff, I would suggest draining the diff and sanding the spot where it was leaking from to clean it up. Then apply some jb weld to plug the hole. That should cover the pin holes that the leaks are usually from. It really depends on how much money you have to spend because a brand new diff will set you back a bit unless you find one from the junk yard. You also have to pay attention to the gear ratio, if it is an ls, and if it is a 4x4. If it is leaking from the sides it is most likely the inner seal but it is a hassle to put a new one in and could put you down a rabbit trail.
