noises are always tricky to diagnose over the internet but I will try to help.

A common problem can be the rose joint in the rear hub where the main lower suspension arm bolts up and would check here first.

Also check the rear road spring is not broken (usually break at the very lower coils inside the arm) or distorted & rubbing on the suspension arm.

Check all suspension link arm bushes for wear & the anti roll bar and bushes.

If all of the suspension is in good order then we do see some problems with the rear shock absorbers causing noises internally but I would want to eliminate all other possibilities first.

Best regards, Paul
