IN ADDITION TO THE ' CLUNK', THE BODY OF THE VEHICLE IS SUBJECT TO A RAPID MOVEMENT AS THE REVERSE GEAR IS ENGAGED.

THE REAR DIFFERENTIAL IS BEGINNING TO MADE A NOISE WHILE MOVING DOWN THE ROAD, YOU CANNOT HEAR IT FROM THE INSIDE THE VEHICLE, YOU NEED TO BE ON THE OUTSIDE WHILE THE VEHICLE IS IN MOTION.
