Thank you for your reply. I understand that the wheel moves - rotating the shock - but the top mount doesn’t - it’s bolted to the body - but the top mount is bolted to the damper shaft - so the damper shaft must also not move - the damper casing rotates around it - my question was is that normal? Am I missing a second bearing that stops the damper shaft rotating - I’ve always thought of a damper as an up-down motion - but I’m thinking now it must be designed to do both - up-down and rotate in its housing.

Apologies if this is a daft question - I’ve contacted KYB and ask this question - watched lots of YouTube videos and read a couple of workshop manuals - still none the wiser.
