Does it bang just once per turn? If I don't have enough WD applied with my HAHA, the stinger will "slip/stick" from side to side in the receiver box during a turn. If I do two left turns, it will only make a bang on the first turn and won't do it again until a right turn...and so on. The more the parts wear in together, the easier the slip/stick. Shims would help that issue...or more WD...but it doesn't bother me, since I know what it is. It's worse on a 2.5" receiver with a reducer in it, since there are more stacked tolerances. They have to be pretty tight turns as well.
