Rear end knocking mystery?

VikingMG · 5th June 2019, 14:13

Just had my zt-t PKK(norwegian MOT) approved but a couple of days later I got a strange rear end knocking...It sounds like its something knocking on the chassis and its audible when i turn sharp to the right or have a slightly uneven road...No knock when I go over speedbumps...

I have inspected drop links,arms,bolts and bushings but nothing points out as the cause of this..Is it possible that something on the top mount of the rear shocks have snapped/broke?

TIA

Hi i had a similar kind of noise on my Rover 75 and i checked all suspension as i was sure it was something rattling,Few weeks later i removed rear brake drums and found the culprit the springs that hold handbrake shoes in place had corroded and fell off on one side,This was giving me intermittent knocking,Just an idea if it returns.
