Detailed Description

Delphi TC3985 is engineered as a direct replacement suspension control arm and ball joint assembly for the front left lower position on 2016-2021 Honda HR-V. The stamped steel arm uses a painted black finish and a non-adjustable design, with pre-installed bushings and a bolt-in ball joint for a service-ready assembly. Delphi applies OE dimensional and material analysis to help maintain proper fitment and consistent suspension geometry for the listed Honda HR-V applications. This part cross-references MOOG Chassis Products RK623316 for the same application.

What This Part Helps Address

• Excessive front-end looseness or play from a worn lower control arm assembly
• Noisy suspension movement caused by deteriorated bushings
• Ball joint wear that can affect steering response and alignment stability
• Uneven tire wear related to suspension component wear
• Clunking or knocking from the front left lower suspension area

Installation Notes and Tips

Verify the front left lower position and confirm the vehicle is a 2016-2021 Honda HR-V before installation. Because this assembly includes the ball joint and bushings, inspect adjacent suspension components, fasteners, and alignment settings during replacement. A professional wheel alignment is recommended after installation to restore proper suspension geometry.

Quality Assurance

Delphi subjects steering and suspension components to temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure testing, to evaluate durability under demanding conditions. The brand also uses dimensional and material checks to support OE-level compatibility for the listed application.
