Detailed Description

Delphi TC4975 is a rear suspension lateral arm built for the Tesla 3, covering 2017-2023 model years in the rear lower rearward position. The arm is made from steel with a tubular body and black painted finish, and it includes rubber bushings to match the original suspension layout. Delphi applies dimensional and material analysis to help ensure OE-level fitment consistency between the original part and the aftermarket replacement. The part number TC4975 is a practical choice when replacing a worn rear lateral arm on a Tesla 3.

What This Part Helps Address

• Rear suspension looseness or play from a worn lateral arm
• Clunking or knocking from deteriorated bushings
• Uneven rear wheel alignment caused by suspension wear
• Excess movement in the rear lower rearward control point
• Restoring stable rear suspension geometry on Tesla 3 vehicles

Installation Notes and Tips

Verify the rear lower rearward position before installation and compare the original arm length, bushing style, and fork end configuration to the new part. Because this arm is not adjustable, final alignment should be checked after installation. Inspect adjacent suspension components, mounting points, and fasteners for wear before completing the repair.

Quality Assurance

Delphi tests steering and suspension components under extreme temperature and corrosion conditions, including sub-zero and high-heat exposure plus extended salt spray testing. That validation process supports consistent performance for Tesla 3 rear suspension service and helps confirm the fit and material quality of TC4975.
