I dont get much twist at all. What happened by accident and actually works really well is when I welded the tire carrier piece on the arm I got a little too much heat into swing arm which caused the bar to bend very slightly upward. So when I close the arm I have to push down on the bar and screw the handle down. There is also a 1/2" tab with a threaded hole for the screw handle to screw into so there is very little space between the swing arm and bumper itself. This opposite upward pressure of swing arm causes no bounce or rattling whatsoever.
