Front Lower Ball Joint for 2001-2005 Honda Civic & More - Delphi TC4279

Help restore precise steering and secure wheel articulation with the Delphi Suspension Ball Joint TC4279, a direct-fit front lower ball joint for the 2001-2005 Honda Civic and the 2001-2005 Acura EL. Delphi builds on its OE experience, testing to the extreme so parts withstand temperatures below -40°C and over 120°C plus 720 hours of salt spray, with extensive dimensional and material analysis for close OE-to-aftermarket compatibility.

• High-quality forgings: manufactured for increased strength and smooth operation.
• Chloroprene rubber boot: improves durability and helps prevent premature failure.
• Micron-tolerance machining: supports durability and smooth joint operation.
• Anti-corrosion protection: applied to each part for corrosion prevention and enhanced aesthetics.

The front lower ball joint links the lower control arm to the steering knuckle, allowing the suspension to move and the wheel to steer. Signs it may need replacing include clunking over bumps, loose or wandering steering, and uneven tire wear. If a worn front lower ball joint is the cause, this Delphi unit replaces it. Sold individually; replacing both front lower ball joints together is recommended for balanced handling.
