I searched the threads but didn't find an exact example of what mine is doing. Had a very reputable 4x4 shop do the lift. 2" Skyjacker lift. Before the Jeep drove perfect as far as vibrations and all. Now it sort of wabbles as soon as I take off from a dead stop for about a second and then when I get to about 38-50 mph it is a whirring noise/vibration. Not a death wabble or anything drastic, just a simple constant vibratory whirring sound. Once I get a little over 50 is smooths out and is just like it was before the lift. Up to about 38 it is the same as before also. Alignment? I have brand new tires and rims about a week old. 31x10.5x15. The Jeep is a 94 6 cyl auto that has 82k on it. Any info would be appreciated. Going to post another item for the motor.
I just lifted my 04 Wrangler 4" and got vibration from the driveshaft. I installed the T-case drop which was supposed to take of the problem but it didnt fix mine. I ended up installing a slip yoke eliminator kit which has taken most of the vibration out. I would guess that you are having a similar problem, did you have the T-case drop installed? I would think with just a 2" lift the T-case drop would work for yours but again that's what I was told about my 4" lift.
