How often do axle seals go out??... on the Intermediate shaft side of my trany i keep leaking oil!!... i refilled it yesterday and most if not all of the oil is prolly gone today. I was thinkin about it, i had the seals replaced about 4 monthas ago, but now im beginning to think that the intermediate shaft has pits in it. Are there anyother seals which should be in there that i am missing.. or do i just have bad luck?? 1) how often do the seals go out (or how many miles)? 2) Could it possibly be the intermidiate shaft is causing the problem? 3)Are there any other seals in the tranny that i could be either missing, or need replacing to stop the leaks? 4) what do you folk reccomened i do?
