The loud noise you hear comes from the red or black cone that seats your ball into the hitch. This comes from water entering the cone which causes the plastic to be scratched. The solution is to call Anderson and they will send you a new cone at no charge. They have a video that shows you how to remove the old cone and install the new one. If you have trouble any place that sells hitches can do it for you for a small price. Anderson says they are aware of the problem and after replacing mine 6 months ago it has worked well.
