Uhm, I had cleaned up excess grease, then re-greased until the usual oozing, took dampers off (well detached) trolley dropped etc. she defo bounces when dropped. However with everything else taken into consideration I can’t quite fathom why both sides would be so different, before swapping the springs to opposite sides the space between rings was approx 40mm both sides. That was with the list to the left.
Puzzled yet again.
