I have a 72 4x4 lifted 4 inches and i have a vibration at 50-60 mph. It is like a drone sound and a vibration at the same time and goes away after 60mph. the driveshaft angles are the same but opposite each other so they cancel out and I tried to shim the rear another degree or two to compensate for axle twist under acceleration and still same thing. any ideas , thanks, Mike
