I'm a very happy new owner of a 1985 CJ7 with a high speed vibration problem. It has a 2/5 inch lift & the shims were there on the springs, but the angle between the transfer case (rear wheel) and the differential was pretty steep, so the mechanic (35 years experience working with another guy with 45 years of experience) installed the kit to drop the transfer case. Now the angle is right on, but the high speed vibration persists. It is bump induced and ranges through some harmonics as bumps are encountered. Today they took the rear drive shaft off & the vibration ceased. The U-joints have been replaced. There is a little looseness in theoutput yoke on the rear wheel drive. The only time I can count on the vibration stopping is if I come to a stop. Hitting the gas, brakes, clutch, etc., has no effect. Can anybody give me some ideas of what is next or am I going to have to sell my grandchild to pay for the repairs or shall I just wait for something to break? Any help would be greatly appreciated. Thanks, drhazel
