I finally found the source of the knock upon acceleration and on lower portion of the vehicle by the spare tire on each side located above the exhaust tips there is a counterweight of some sort on each side... Does anyone here know what they are for? The seem to swing freely and very easily. The Driver's side on mine swings and taps another body piece underneath.
