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.

I suspect this problem had been lingering for a while, but the mechanic never noticed it. I wore through two sets of tires quickly, two steering shocks, a set of wheel bearings, and the drag link. Get these fixed before they cause other expensive repairs!
