My QP has started to make a worrying sideways shimmy or jerk when I cross over a change of road surface at speed. Basically if I cross a raised white line or just a longitudinal change of tarmac quality (I live in Gloucestershire!) at speed, the back end seems to leap a few inches from one side to the other. Not too violent, but noticeably unstable. I've only started noticing it in the last couple of weeks. Do we think this is a suspension thing, or a tyre thing, or what?
