Keep the front suspension pivoting smoothly and the steering tight with the Delphi Suspension Ball Joint TC2903, a front right lower IS300 ball joint that drops in as a direct-fit replacement for the 2001-2005 Lexus IS300. This joint forms the pivoting connection between the lower control arm and the steering knuckle, letting the wheel travel up and down and turn while carrying suspension loads.
Delphi brings its OE safety expertise to its aftermarket steering and suspension portfolio, testing to the extreme for OE-level performance — parts withstand temperatures below -40°C and above 120°C and endure 720 hours of salt spray, backed by extensive dimensional and material analysis for close OE-to-aftermarket compatibility.
- Forged strength: Manufactured with high-quality forgings for increased strength and smooth operation.
- Chloroprene boot: Uses a chloroprene rubber boot to improve durability and help prevent premature failure.
- Micron tolerances: Machined to micron tolerances for durability and smooth joint operation.
- Anti-corrosion protection: Applied to each part for corrosion prevention and enhanced aesthetics.
Signs this ball joint may need replacing include clunking or knocking from the front suspension over bumps, loose or wandering steering, and uneven tire wear. Diagnose the cause before ordering. Sold individually; order the matching side as needed.
