That clunk is very annoying, only a little bit of movement in the tongue will cause it thats why I always have a bit of plastic to shim it, I think you will find that will get rid of it. The ball adjuster is on top of the trailer hitch point and is just a bolt with lock nut usually, and the end of the bolt is what the ball rides on, that way the bolt takes the wear not the cup.
