MINI Cooper – Rattling Knocking Noise from Rear Axle

MINI Cooper R55,R56,R57 With sport suspension.

A rattling and/or knocking noise may be heard from the rear axle and/or rear suspension while driving over uneven roads.

The inner diameter of the stabilizer bar mounts may be too large for this application.

Use a caliper gauge to determine whether the rear stabilizer bar is 16mm (1) (non-sports suspension). If the stabilizer bar is 16mm, replace the stabilizer mounts (2) with P/N 33 55 6 754 823.
