well folks I have a 1999 XJ skyjacker 3in lift, it had a vibration and grinding when I first bought it. I had 2 new wheel bearings installed and rebuilt the front end. Noises are gone vibs still there. Next I had installed a t/c drop kit and removed the rear shims. Low speed vib was reduced but high speed (65mph) got worse. I removed the front drive shaft and had no change in vib. The vibration is not rpm related, only speed related. The u-joints are tight, but does that mean they are ok? Anyone have any ideas? Burnsville OFF-ROAD did some good work, but they can't look at it any more untill the guy gets back from SEMA. I don't want to wait that long.
Thanks
