Vibration Issues near Model 20 Transfer Case

Hey guys, I got an Issue around my transfer case, it feels like the rear driveshaft u-joints are shot, but I checked them, and they seem fine, the yoke seal on the rear driveshaft yoke on the t-case is busted, and has been slowly leaking, Any ideas on what this could be? I notice it most on deceleration just letting off the gas...

Could use more info...

Is everything stock... driveline and suspension?

A new suspension lift could explain the vibration.

Vibration? Bump steer? Wandering? Read the article (sticky) on Steering, suspension, and driveline.

ditto . . . . with Gojeepin. . . . bet your lifted and have a drive shaft that isn't keeping up with the program. You must keep both ends of the drive shaft at the same angel to transfer case yoke and the rear end to avoid vibration. You only can get away with having rear end pointing to the transfer case, uneven angels, when you are using double cardigan (sp?) driveshaft set up.

It does have a stock driveline, and a small lift, but this is a new occurring issue, it just started happening a few weeks ago, so I'm 99% certain its not the driveshaft, I wanna think it could be a clutch-related vibration...
