Delphi TC4597 Suspension Control Arm and Ball Joint Assembly - Front Right Lower

OE-Style Front Right Lower Control Arm

Delphi TC4597 is a suspension control arm and ball joint assembly for the front right lower position. It is built with an aluminum control arm, pre-greased ball joint, and included bushings, dust boot, castle nut, cotter pin, and mounting hardware for a direct replacement on select Hyundai and Kia EV and hybrid applications.

Key Features

• Part number TC4597 for the front right lower suspension position
• Aluminum control arm construction with casting/forged design
• Pre-greased ball joint with threaded stud and machined mounting type
• Includes bushings, dust boot, castle nut, cotter pin, and mounting hardware
• Black rubber bushings and chloroprene rubber dust boot
• Standard replacement grade with no grease fitting and no adjustability
• Clockwise (right) thread direction

Detailed Description

Delphi TC4597 is engineered as an OE-style suspension control arm and ball joint assembly for vehicles that use a front right lower setup. Delphi applies dimensional and material analysis to match OE fit and function, and the part is tested across extreme temperature and corrosion conditions to verify durability in demanding road environments. The aluminum arm, pre-installed ball joint, and included service components help streamline replacement while maintaining the original suspension geometry.

This part cross-references Mevotech Supreme CMS901281 and Suspensia X23CJ0003 for the same application. It is a direct-fit option for 2019-2023 Hyundai Kona Electric, 2020-2023 Kia Soul EV, 2017-2022 Hyundai Ioniq, 2017-2022 Kia Niro, and 2019-2022 Kia Niro EV, front right lower. Searchers looking for a Hyundai Kona Electric front right lower control arm, Kia Niro EV suspension control arm assembly, or Hyundai Ioniq lower ball joint assembly will find TC4597 listed for these applications.

What It Helps Fix

• Clunking or knocking from the front right lower suspension
• Excessive play from a worn ball joint
• Uneven tire wear caused by suspension looseness
• Steering pull or wandering related to worn control arm components
• Failed bushings, torn dust boot, or corrosion-related wear

Installation Notes and Tips

Verify the front right lower position, thread direction, and vehicle application before installation. Inspect adjacent suspension components, alignment angles, and mounting points for wear or damage, and perform a wheel alignment after replacement. Because the assembly includes a pre-greased ball joint and mounting hardware, installation can be more straightforward than rebuilding individual components.

Quality Assurance

Delphi uses OE-focused engineering and validation methods for its steering and suspension portfolio. TC4597 is evaluated for temperature resistance and salt-spray exposure, with dimensional and material checks used to support OE-level fitment consistency for select Hyundai and Kia applications.
