did you install the Revtek Diff Drop Kit when you put in your lift? I just installed mine last week and it fixed any steering wheel vibe's I had in me lifted '98. The problem with that was the the CV's were at extreme angles due to the lift and they would vibe, the diff drop lessened the angle and therefore fixed the minor vibe. Mike at Xtreme can get them for you for ~30.

 

good point- i have not installed a diff drop yet. i just ordered one this week. i am waiting for it!
