Steer with confidence and help maintain precise wheel control with the Delphi control arm and ball joint assembly, MPN TC5574. This front left lower unit installs as a direct-fit replacement for many vehicles, among them the 2007-2012 Chevrolet Silverado 1500, 2007-2012 GMC Sierra 1500 and 2007-2012 Chevrolet Tahoe — see the Buyer's Guide tab for the full list. Delphi applies its OE steering expertise to the aftermarket, testing to the extreme for OE performance.
- Validated to OE: withstands temperatures below -40°C and over 120°C plus 720 hours of salt spray, with dimensional and material analysis for OE-to-aftermarket compatibility.
- Quality-checked material: 100% crack detection and ultrasonic flaw detection help confirm materials match OE specifications.
- Precision ball stud: machined to micron tolerances for durability and smooth joint operation, with robot welding for consistent quality.
- Anti-corrosion protection: applied to each part for corrosion prevention and enhanced aesthetics.
The control arm locates the wheel and the integrated ball joint lets it pivot for steering and travel; worn signs include clunking on bumps, loose or wandering steering, and uneven tire wear. If a failed original arm or ball joint is the cause, this front left lower assembly replaces it.
