I spray the sides of the bolt plates where the bottom plate bolts onto the pin box with the rotating head with white lithium grease and the clunking went away. It does come back periodically and I will spray it again. I have checked that these bolts are tightened to the proper torque also. I don't remember what that was, but 120 lb. ft. seems right.
It's hard to describe, but I'll try and get some pics when it gets light enough out.
Thanks for the reply Robert. I have sprayed the swivel bolts on the Rotoflex with lithium grease as you suggested, but have not torqued the bolts. But in my case, I could (B&W) and can (Comfort Ride) actually see the hitch jaws opening slightly and then closing back. The closing is what was and is making the clunk sound. I will torque the Rotoflex swivel bolts before we head out again.
