Only when i am towing this fault happens. Its NOT the jocky wheel grounding out as i have checked. When going over bumps, and weight is forced suddenly down onto the tow ball, there is what i can explain as metalic clunk clunk from the rear underside of the Jeep. As if something metalic is hitting on something thats moving. We have had the car checked over by the local towbar company and a garage but cant find anything. It only does it when towing, even a trailer with nothing in it. The only abnormality is its got a alko hitch ball and the trailers are not alkco hitches ? Any ideas ?
Possible that the ball size is wrong for the tow hitches
they do come in two sizes and there is just enough difference to allow movement at the ball

I think the tongue weight rating on the stock hitch is 600 lbs, so you are over that. You probably want to level out truck to handle better when towing, so the best way is to get air bag helper that raises the back end.
