Detailed Description

Delphi TC3984 is engineered as a front right lower suspension control arm and ball joint assembly for the 2018-2021 Honda Accord. It uses an aluminum arm with a forged/cast construction, rubber bushings, and a pre-greased ball joint to support stable suspension movement and consistent steering feel. Delphi validates its steering and suspension components through temperature and corrosion exposure testing, including sub-zero and high-heat conditions plus extended salt spray evaluation, to help confirm durability in demanding road environments.

This part cross-references Mevotech Supreme CMS601269 and OE number 51350-TVA-A04 for the same application. The Delphi TC3984 is a practical choice when replacing a worn front right lower control arm on a Honda Accord and restoring proper suspension geometry.

Common Problems This Part Can Help Address

• Clunking or knocking from the front suspension
• Excessive play from a worn ball joint
• Uneven tire wear caused by suspension looseness
• Steering wander or reduced front-end stability
• Vibration or noise from deteriorated bushings

Installation Notes and Tips

Verify the front right lower position and confirm vehicle fitment before installation. Because this assembly includes a threaded ball joint stud and mounting hardware, follow the vehicle service procedure for torque specifications and alignment checks after replacement. A professional wheel alignment is recommended after suspension work to help maintain proper handling and tire wear.

Quality Assurance

Delphi applies OE-based engineering and material analysis to its aftermarket steering and suspension portfolio. This part is tested for temperature extremes and salt spray exposure to support corrosion resistance and long-term performance expectations in normal road use.
