I was wandering what all has to be done to replace the front output shaft seal on the transfer case in a 01 dodge? I was under there today whenver the truck was on the rack at the muffler shop and noticed that something on the transfer case was leaking. I got to looking and I think that it is comeing from that seal and getting slung all of the transfer case and under the cab. I am gonna try cleaning it all off and see where it start coming from first. Also what kind of fluid is used in these? I used ATF+3 in my 97 when we was at shiloh one time and it worked. Is that what is supposed to be used or shoudl I use a gear oil?
