What It Helps Address

  • Excessive play from worn bushings
  • Clunking or knocking from the rear suspension area
  • Uneven rear tire wear related to suspension alignment issues
  • Loss of precise rear wheel location under load

Installation Notes and Tips

Fits 2021 Tesla 3, rear lower forward. Verify mounting hole diameter, arm length, and bushing orientation before installation. Because mounting hardware is not included, reuse or source the correct hardware separately. After replacement, a professional alignment is recommended to confirm rear suspension geometry.

Quality Assurance

Delphi tests suspension components for temperature extremes and extended salt-spray exposure, and uses dimensional and material analysis to support OE-style fit and durability. Part number TC4940 reflects Delphi’s aftermarket steering and suspension expertise for the Tesla 3 application.
