Report: Premature Tire Wear Due to Cracked Lower Control Arm Bushings
Mercedes-Benz E320 4MATIC Problem
Average Mileage: 155,000 mi (110,000 mi - 200,000 mi)
Irregular and premature tire wear can be caused by the lower control arm bushings cracking, resulting excessive movement at the control arm pivot point. Ball joints can also wear out prematurely, causing similar tire wear symptoms. I some cases it may be necessary to replace the lower control arm, including bushings & ball joint to correct this concern.
Ball Joints went. but at 200K you can't be surprised.

Irregular tire wear and groaning noise while going downhill and stopping. Mechanic wants to replace whole control arm not bushing. Any advice?
