    ok i just went under to do some inspections and i noticed that my tcase is leakig from the slip yoke. Could this be the out come of the 4" lift ?

    It looks like the slip yoke is kinda far out from the tcase .

    Is there a seal in there that i need to replace?

    or should i get a driveshaft thats longer then my stock driveshaft?

    help this is my Daily Driver!

    can you tell if it is leaking from where the tcase meets the driveshaft.. that would be the seal.. oorr where mine leaks is the part of the driveshaft that goes into the tcase.. there is a plug that the factory put in the driveshaft, just was pressed in there so it sometimes leaks.. u can take ur driveshaft off and jb weld it, sometimes that works. sry if this is a lil confusing.

    really, a good picture of the slip shaft in the tcase would help, but a good rule of thumb, is at rest, half the slip should be in the tailshaft housing, at least

    it is probably the seal, but i would reccomend the pic first, then maybe pull your dshaft out and see how much of the slip is actually in the tcase... make sure you block the wheels before pulling the shaft

    hmm.. can you tell if its leaking from the tailshaft seal? or from the driveshaft itself? iirc it has a small plug in it that can come out... does the section of shaft in the tcase seem solid and secure? remember jounces and bounces make that thing move in AND out...

    wowbro, you gotta give it more than 4 minutes,

    you have to remove the driveshaft, then use a seal puller to remove the seal, and there is a special tool to install that seal, but you can use a 2x4 very carefully to install it

    If you go to the trouble to replace the rear seal, consider replacing the output shaft bushing too. If this wears, it will allow too much fluid to the rear seal, and it will leak out. The GM part # is 03978765. Its about $5 or so. It is located behind the rear seal, and the output shaft goes through it. you would need to remove the tailshaft housing to replace it.
    Just a thought...
