Application Details

Compatible with 2004, 2005, and 2006 Acura TL models in the front left lower position, Delphi TC5571 is built for suspension service where the original control arm has worn bushings, developed play, or corrosion-related damage. Delphi applies OE-focused dimensional and material analysis to help maintain proper part-to-vehicle match, and the component is tested across extreme temperature ranges and salt-spray exposure for durability in demanding road conditions. This part cross-references MOOG Chassis Products RK641543 for the same application.

Common Problems This Part Can Address

• Clunking or knocking from the front suspension
• Excessive play in the lower control arm assembly
• Worn or cracked rubber bushings
• Uneven tire wear caused by suspension looseness
• Steering pull or unstable front-end feel on Acura TL models

Installation Notes and Tips

Inspect the ball joint, adjacent bushings, and alignment components before installation. Because mounting hardware is not included, reuse or replace fasteners as required by the vehicle service procedure. A professional wheel alignment is recommended after replacing the front left lower control arm on a 2004-2006 Acura TL.

Quality Assurance

Delphi uses OE-based engineering practices for its steering and suspension portfolio, with dimensional and material checks intended to support proper fit and consistent performance. The part is also subjected to temperature and corrosion testing to verify durability under harsh operating conditions.
