The vibrations after a lift come from the rear drive shaft being at too high an angle coming out of the transfer case. to solve the problem, I had to lower the trans mount/skid plate a half inch. My lift is just stock springs with a 2" econo lift. The econo lift consists of 4 add-a-leafs, 4 Heckthorne shocks, and a Heckthorne steering stabilizer. Got it from J.C. Whitney for $100.
You can buy lowering kits for the skid plate, however, since I, (like Al Bundy), am married with children, I used 6 half inch nuts in between the frame and skid plate. Hope this helps. :-D [addsig]
