The lower control arm bushings can wear and crack, resulting excessive movement at the control arm pivot point, leading to irregular and premature tire wear. Worn Ball joints can also cause 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.

Both control arms broke, but was able to drive 45 minutes like that, crazy. Also my 1999 e430 EATS tire-rods for lunch, replace every year now, ball joints also. Tires in front get bald FAST. Now when I turn the lights on all power failure. damn it
Lower Control Arm rusted to the point that it craked while driving. Could have killed me.
