Keep your front suspension pivoting smoothly with the Delphi ball joint TC5238, a front lower joint that connects the lower control arm to the steering knuckle and lets the suspension articulate while you steer. It drops in as a direct-fit replacement for the 2005-2010 Ford Mustang — see the Buyer's Guide tab for the full engine-level fitment.
Delphi applies its OE steering expertise to this aftermarket joint, testing to the extreme: parts endure temperatures below -40°C and above 120°C plus 720 hours of salt spray, with extensive dimensional and material analysis for close OE-to-aftermarket compatibility.
- Forged construction: built with high-quality forgings for increased strength and smooth operation.
- Chloroprene rubber boot: improves durability and helps prevent premature failure by keeping contaminants out.
- Micron-tolerance machining: machined to micron tolerances for durability and smooth joint operation.
- Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.
Signs this front lower ball joint may need replacing include clunking or popping over bumps, wandering steering, and uneven front tire wear. Sold individually; ball joints install per side, so consider replacing both sides together for balanced steering. If a worn ball joint is the cause of your symptoms, this replaces it.
