• Delphi part number TC8273

Detailed Description

Delphi TC8273 is engineered for the front left upper position on Tesla S vehicles from 2012 through 2021. Delphi applies OE-focused dimensional and material analysis to help ensure proper fitment between the original and replacement part, while its validation testing includes exposure to extreme temperatures and extended salt spray conditions. For Tesla S front suspension service, this control arm and ball joint assembly provides a direct replacement option built around OE-style construction and materials.

This part cross-references Tesla OE numbers 1043965-00-B and 600653200A for the same application.

What It Helps Address

• Front-end looseness or play from a worn upper control arm
• Clunking or knocking noises from the front left suspension
• Uneven tire wear related to suspension geometry issues
• Steering instability caused by worn ball joint or bushings
• Restoration of proper front suspension alignment on Tesla S

Installation Notes and Tips

Install this Delphi TC8273 assembly at the front left upper position only. Because the ball joint uses a pinch-style stud and the arm is not adjustable, verify alignment settings after installation and inspect adjacent suspension components for wear before completing the repair. Confirm vehicle year and position against the Tesla S fitment listing before ordering.

Quality Assurance

Delphi uses OE-based engineering and validation methods for its steering and suspension portfolio. This control arm assembly is tested for temperature extremes and corrosion resistance, supporting consistent performance in demanding driving conditions.
