You need a panhard bar to make sure the diff asssembly stays centered when in flex. Now this will be effective if the bar is parrallel to the ground when the truck is sitting still (no flex). Usually when people put a lift on a truck, the bar will not be parrallel anymore and will cause the symptoms you state.. To fix this, you need to put back the bar parrallel... so usually a panhard bar drop bracket needs to be installed/fabricated to bring back good geometry....
