so here's my issue. the other day i was driving and major vibrations started in the drivetrain. seemed like it was only the rear and was thinking ujoint because when i let off the accelerator i could feel that "feel" of a bad ujoint. well the ujoint, center ball, and yoke all let go and the driveshaft was destroyed. after pulling over and checking damage, continued on my way and now front does the exact same thing. anything over 30 and the whole jeep vibrates unbelievably, and not like a death wobble. rebuilt driveshaft but it still vibrates. tcase seems tight, trans/tcase mount seems tight. gonna get shaft balanced this week but front and rear shouldnt have both become unbalanced at once... any ideas???

(97 TJ, 3.5"lift, sye, cv driveshaft, 1"mml, 1"bl, flat skid)

thanks
 
I found my problem to be the transmission mount. After changing the broken one life was much better. It may be worth dropping the plate and verifying that it hasnt truely fallen apart.
 
well a freshly rebuilt balanced driveshaft fixed the issue. seems that the ujoint went bad, caused destruction, thus becoming unbalanced when flug from jeep.
