Product Details

Delphi TC3998 is engineered as a direct-fit front right lower suspension control arm assembly for the Honda Odyssey. It combines an aluminum arm, pre-installed ball joint, rubber bushings, and a dust boot to restore the original suspension connection point between the chassis and wheel assembly. Delphi subjects its steering and suspension components to extreme temperature and salt-spray testing, along with dimensional and material analysis, to help maintain OE-level fit and material consistency. If you are replacing a worn front right lower control arm on a 2018, 2019, 2020, or 2021 Honda Odyssey, TC3998 provides a service-ready assembly for that exact position.

Common Problems This Part Can Address

• Clunking or knocking from the front suspension
• Excessive play from a worn ball joint or bushings
• Uneven tire wear caused by suspension looseness
• Steering wander or reduced front-end stability
• Noise or vibration from a deteriorated lower control arm assembly

Installation Notes and Tips

Verify the front right lower position before installation and compare the old part to the new assembly for mounting-hole and bushing layout. Because this unit is pre-greased and includes the ball joint, bushings, dust boot, locking nut, and mounting hardware, it is ready for replacement service once the original component is removed. A professional alignment is recommended after suspension work to confirm proper geometry and tire tracking.

Quality Assurance

Delphi applies OE-based engineering and validation to its aftermarket steering and suspension portfolio. TC3998 is tested for temperature extremes and salt-spray exposure, and its dimensions and materials are analyzed to support consistent fit on the specified Honda Odyssey applications. Fits 2018-2021 Honda Odyssey, front right lower. Delphi TC3998 is a direct replacement for the listed application.
