    Wow, been a little while since I was here...

    Anyhoo, I finally replaced my rear driveshaft and slipyoke, and now my T-case leak has gone from a few drops a day to 1 quart a week! I replaced the T-case rear output seal when I installed the "new" slipyoke (used grease inside the seal runner, little silicone around the OD of the seal), and now it seems to be leaking from the sealing surface itself. I did have to clean up the shaft portion of the slipyoke due to some light rust, but there's no pitting or grooving. Other than replacing the seal again, anyone have any suggestions on how to fix this?

    Inside the slip yoke of the driveshaft isn't it supposed to be epoxied or something?

    If you still have the 208, check the rr ext bushing or the plug on the slip yoke .The plug on mine came out and spewed fluid

    OK, some clarification:
    I JB Welded the outside of this slipyoke where the "plug" is, and the inside of the shaft at the very bottom. This slipyoke is well-sealed, and it's no longer the source of the leak. My old one had that leak...
    My new leak is at the output seal of the case. It's leaking FROM THE SEAL, around the shaft portion of the slipyoke, as if the shaft diameter was too small for the seal to do it's job. I didn't think I took too much material off when I cleaned up the shaft, but I suppose it could have been borderline-undersize before I took the rust off. Or the seal could be a piece of crap.
    Does NAPA or someone else make one of those "speedy-sleeve" things for a T-case slipyoke? What does installing one of those things involve? Thanks.
