OE-Style Fit and Construction

Delphi applies OE engineering practices to its aftermarket steering and suspension portfolio, and TC4855 reflects that approach with careful dimensional and material matching. The assembly is pre-greased, uses a rubber dust boot, and is built as a standard replacement for front lower suspension service. This part cross-references Mevotech Supreme MS90534 for the same application.

Compatible with 2022-2024 Hyundai Elantra N, 2022-2024 Hyundai Ioniq 5, 2023-2024 Hyundai Ioniq 6, 2022-2024 Hyundai Tucson, 2022-2024 Kia EV6, and 2023-2024 Kia Sportage in the front lower position. Delphi TC4855 is a direct-fit service part for these applications, including Hyundai Elantra N front lower ball joint replacement and Kia EV6 front lower suspension repair.

Common Problems This Part Can Address

• Front-end clunking or popping from worn ball joint joints
• Excessive play in the lower suspension connection
• Uneven tire wear caused by looseness in the front suspension
• Steering wander or imprecise road feel
• Boot damage that can allow contamination into the joint

Installation Notes

Verify the front lower position and compare the original part before installation. Because this is a bolt-in, pinch-bolt style assembly, proper torque and fastener alignment are important during service. Inspect the surrounding control arm and mounting points for wear, and confirm the replacement matches the vehicle’s OE configuration before final assembly.

Quality Assurance

Delphi subjects its OE-style steering components to temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure testing. That validation process supports consistent fitment and durability for front suspension service on Hyundai and Kia applications. Part number TC4855 is built for standard replacement use in the front lower suspension position.
