Hard to find front suspension hollow wobble noise
 

My local garage is stumped v40 78k miles developed this strange hollow wobble light knocking after going round a roundabout and NS wheel dropped into a pot hole. All suspension checked and ok it’s not strut mounts, spring, drop link , anti roll bar bushes. Inner track rod ends changed as slight play found but hollow wobble knocking still there! Garage can’t replicate on their ramp with shakers engaged either? Maybe steering rack itself? Does it have plastic bushes like BMW? No steering issues or vibration it handles fine in corners and straight line. Engine under tray removed and nothing sitting in it so refitted securely

Loose disc pad . Bobbling about . One drove me nuts on a V70 some time ago!🤔
