This suspension control arm connects the wheel assembly to the vehicle's chassis. It locates the wheel, and its bushings let it pivot as the suspension moves.
Signs a control arm may need replacing include clunking or knocking over bumps, worn or cracked bushings, uneven tire wear, and an alignment that won't hold. Have the rear suspension inspected to confirm the cause before you replace any parts.
