I'm used to removable ball mounts having a little bit of noise and movement but I'm finding that the receiver on the X3 seems to be a little oversized. I'm using an anti-rattle clamp a lot to try and settle the ball-mount down otherwise it sounds like it is beating up the receiver. It isn't very convenient since it means I need to wrench the clamp on every time I install the ball mount (I remove the ball when not towing).
Has anyone found a good tight fitting class III ball mount for the X3 or am I stuck using the clamp?
