Transfer case blowing fluid from somewhere

[shorepatrol]

Had a tight vibration start up a week or so ago. Crawled under the truck to check the u joints, they were tight and everything was dry under the truck. I look at it again today to change the u joints and the the transfer case is spewing fluid everywhere. Any help appreciated

Update....... ujoints and mount were bad. vibration caused the tcase to loosen from tranny enough to leak AND pull tranny fluid into tcase.

That's not what caused that. Sorry to say. There's a seal that needs replaced. Very common.

Yep, the seal was replaced and the snap ring update done while they were in there.

Did you put a new seal on the transmission output shaft between the tranny and the transfer case? Because that was likely the onpy problem. Seen it literally a thousand times.
