Quick facts
- Part: Delphi TC3781 control arm
- Also called: suspension control arm
- Fits: 2006-2010 Kia Optima and other vehicles
- Position: Front left lower
- Condition: New
A worn suspension control arm can show up as a clunk over bumps, uneven front tire wear or steering that pulls to one side, but other suspension parts can produce those symptoms too. Before replacing anything, park the car with the engine off and look for uneven wear across the front left tire; a shop can inspect the arm for cracks, bends and play. If the arm is the cause, this one replaces it.
