In this video I replace the rear of the two lower suspension arms on the front suspension; in Mercedes speak it is called Rear Spring Control Arm. This video is applicable to all AIRMATIC (air suspension) cars. For non AIRMATIC equipped cars the design of the conventional shock absorber means the lower join and the anti roll (sway) bar drop link is slightly different but the method of change is exactly the same.

I replaced it having realised that the joints were worn when replacing other suspension components, however, it was noticeable that the steering input was a little vague with a degree of free play between turning the steering wheel and the wheels turning. It is widely reported that original arms can wear out in as little as 50k km (30k miles).

This MEYLE HD part has a larger ball joint than the original part which should reduce the wear rate as the it means that the internal friction surfaces are larger and thicker. Only time will tell but the price difference between this and the OE LEMFORDER part is negligible.
