Steer with confidence and keep your front wheel located with the Delphi control arm and ball joint assembly (TC3226), a direct-fit replacement for the front left lower forward position. The control arm links the steering knuckle to the chassis to locate the wheel through suspension travel, while its integrated ball joint allows the articulation needed for steering and ride motion. Delphi applies its OE steering expertise to this aftermarket part, with extensive dimensional and material analysis for close compatibility between the OE and aftermarket component.
- Tested to the extreme: validated at temperatures below -40°C and above 120°C, plus 720 hours of salt-spray exposure.
- Quality-checked materials: 100% crack detection and ultrasonic flaw detection help confirm materials match OE specifications.
- Precision ball studs: machined to micron tolerances for durability and smooth joint operation.
- Built for consistency: robot welding for repeatable quality, with anti-corrosion protection applied for corrosion prevention and enhanced appearance.
