96 2 door xj, ax15, both rear ujoints are new. Horrible driveline shake in clutch pedal and whole car once the 45-55mph deathwobble stops. Lot of problems in this XJ
On a lift, the rear driveshaft can be wiggled by hand on the transfercase splines.
Lift is 2 inch spacers up front, bent rear leafs with bottom leaf cracked off on both sides, an a RC add a leaf in its place. It's about a 2 inch in front, whatever in the rear it appears from outside rear is slightly higher. Stock shocks all around.

Both rear u joints are new. Rear driveshaft has snapped u rear strap clamps several times so its dented in some spots from snapping on me and previous owner a few times shifting too hard.

Pics of driveshaft angle, and other problems. Below. Where do I start?

The drive shaft yoke should not have any wiggle at the splines. That aside, I think that you should have the drive shaft balanced as the thing had bounced around the ground a few times! Good luck and keep us posted!

 

will do, putting a front diff thats not bent with good u joints, and a new gas tank this weekend, hopefully we get this d/s thing straightened out.

 

videos of the driveshaft wobble. WTF?? Do i need a longer yoke? Don't feel like its slid onto the splines far enough. I did recently put a yoke in it.But it didnt shake till i fixed rear leaf sag

 

get a new longer ds made plain and simple,wobbleing like that will wear out rear tc bearing causing more costly issues than yu have now

 

Mannn i thought I needed a sye or something. Why is it too short What gives. How much will this run me?

 

Could be that your two inch lift is actually higher than that. When you lift the vehicle you extend the the distance from the transfer case to the axles causing the drive shaft to pull out some. The above answer is sound!

 

putting a tc drop in will bring it back some also when my ds was done it was around 150.00
