Engine/Transmission (1998.5 - 2002) transmission leak

[rtwingson]

I have a leak from the seal on the transfer case tailshaft. My local transmission shop has replaced it three times, this last time with a "heavy duty" seal.

The leak starts up again the next day. Has anyone else had this problem and found a cure?

Did they check and see if the bushing in the tail shaft was good,or a groove or rough seal fit on the yoke that slides up on the shaft... . ? Where the seal runs... and i think theres a vent on the transfer case make sure it's not pluged building up preasure...

Good to hear from a fellow machinist! Yes, the bushing has been replaced. The yoke has been inspected. I am going to check for a vent tonight.
