With a fixed length stock track bar when you lift the suspension the track bar pulls the axles to one side, this can be corrected getting adjustable track bars or correction brackets.
The added lift is the cause of the driveline vibration, with the short wheelbase it puts the rear drive shaft at a steep angle that can result in vibrations. The vibes were not that bad with the stock drive shaft but the added angle caused the joints to wear out, I replaced with an aftermarket double cardan ujoint driveshaft and I feel the vibration.
