I have not change the wheels and tires yet, same set that was on before I started the swap. I changed to a conversion u-joint where the DS meets the 9" yoke but left the front u-joint alone as it seemed fine. I have not put shocks on the rear yet, could this cause a vibration? I would think it would just feel bouncy in rear and it does, but not vibrate.
