Delphi TC4576 Suspension Control Arm and Ball Joint Assembly - Front Right Upper

OE-Style Front Right Upper Control Arm

Delphi TC4576 is a front right upper suspension control arm and ball joint assembly built for direct replacement service on select Tesla applications. It combines a steel control arm, pre-greased ball joint, rubber bushings, and a dust boot to support consistent steering and suspension operation.

Compatible with 2017-2023 Tesla 3 and 2020-2023 Tesla Y in the front right upper position, this Delphi assembly is built for buyers looking for a standard replacement part with OE-focused fit and material selection. Delphi TC4576 is also cross-referenced to Mevotech Supreme CMS95135 and MOOG Chassis Products RK623789 for the same application.

Detailed Description

Delphi applies OE-level dimensional and material analysis to its steering and suspension portfolio, and TC4576 reflects that approach with a direct-fit design for Tesla Model 3 and Tesla Y front right upper service. The assembly uses a steel arm with black painted finish, rubber bushings, and a pre-greased ball joint to help restore proper suspension geometry and joint movement. Delphi TC4576 is engineered for the front right upper location and is built to match the original application requirements for 2017-2023 Tesla 3 and 2020-2023 Tesla Y.

Delphi tests components across extreme temperature ranges and salt-spray exposure to evaluate durability in demanding conditions. That validation process supports consistent fitment and material compatibility for replacement work on Tesla Model 3 and Tesla Y suspension systems.

What It Helps Address

• Clunking or knocking from the front suspension
• Excessive play in the upper control arm or ball joint
• Uneven tire wear caused by worn suspension joints
• Steering looseness or wandering at the front right corner
• Noise from deteriorated bushings or dust boot damage

Installation Notes and Tips

Install TC4576 at the front right upper position only. Verify the mounting hole diameter, bushing dimensions, and ball joint stud style against the original part before installation. Because the assembly is pre-greased and non-greaseable, no routine lubrication point is provided. Always torque fasteners to the vehicle manufacturer’s specifications and perform a wheel alignment after suspension replacement.

Quality Assurance

Delphi uses OE-focused engineering and durability testing for its aftermarket steering and suspension parts, including temperature cycling and extended salt-spray exposure. TC4576 is a standard replacement assembly built to support consistent fit and function on Tesla Model 3 and Tesla Y applications.
