thanksLPB said:If the control arm is bent you could have also bent the damper enough to cause it to wear rapidly and/or respond atypically. Car will not track well and be prone to rapid tire wear. Could also contribute to a loss of control in an emergency. You need to replace it ASAP. The facility who performed the alignment should have notified you of their inability to perform same due to the condition of the A-arm.
