Quoting AndreArnez:
so having a bad yolk isnt the reason its leaking tranny fluid?
Wow OK this thread needs some clarification. Your transfer case is NOT your transmission so it can't be leaking "tranny fluid."
Your transfer case flairs out on the end the drive shaft goes in to, is it leaking there? If so its probably your transfer case tail seal.
If its leaking on the backside of the yoke, that's the recall that all of our cars should have had at one point or another.
Where I'm pointing is where the yoke leaks. This yoke on the right hand side is what the recall kit consists of, but its missing the u-joint or whatever its called.
