Can someone direct me on info on changing the seal on a irs without dropping the whole rearend. I have a small leak and would like to reseal it myself. And any recommadation on what oil to replace it with.

Do you have a billet flow brace on it?

Yes, I got one and thats why I wanted to reseal the diff. It has been leaking very little, a drop here and there on the floor. I was going to put the brace on and thought i might as well reseal the diff. I don't race it that much but it is a good piece of insurance to know that it is there. I have checked the diff oil time to time to make sure that it is ok.

Go get "the right stuff" from permatex at the auto store to seal the cover. 75-140 Synthetic lube. Friction modifier if the lube doesn't already contain it. You have to remove the half shafts from the center section. Then remove the center section. It has been a long time since I did mine so I don't recall all the steps. Plan on a day if you are doing it at home.
