front drive line vibration
I have a 94 XJ and just installed a 4.5" RC lift kit. I have a front drive line vibration only in 4X4 and I cant remove the front drive shaft when the front wheels are off the ground it wedges the drive shaft between the front diff and the T case I have to have all 4 wheels down to remove shaft and most of the drive line slack is used up. I installed the 1" TC drop that was supplied in the kit. Could the TC drop be causing the problem by raising the front pinion angle? The drive shaft U joints and CV joint is good and confirmed by a drive shaft shop. I have had the front end alinged and TC output shaft bearings checked and Ft. diff brgs checked. I drive at higher speeds in 4WD 30 ish MPH on slick roads in the winter other wide it would not be a issue. Thanks for any help.

T case drops will put more of an angle on your front shaft but not usually enough to hurt much. If by letting the front wheels droop your shaft is fully colapsed then I'm guessing something isn't right, like the control arms are too short.
