I don't have the revolution, but when I first got my hitch it never made a cluck when I started or stopped. I then had to remove my hitch to haul something in the back of my truck. I then put the hitch back in and now it clunks when I start and stop. Then only thing that I can think is the little rubber spacers that were on base that the locking pins go through. The kept preventing me from putting the pins in so I left them out. In the spring I will try to out it back in with those rubber spacers and see if the clunking stops.
