The lower control arm positions the wheel and works with the ball joint to permit steering and suspension travel. Worn bushings or a failing ball joint can produce clunking or knocking over bumps, loose or wandering steering, and uneven tire wear. If a worn front left lower rearward arm is the cause, this assembly replaces it; diagnose the source of the symptom before ordering.
