Detailed Product Overview

The Dorman 520-079 is engineered as a replacement control arm assembly for Tesla S and Tesla X vehicles in the front left lower forward suspension location. Its steel casting/forged construction, threaded ball joint stud, and bolt-in, machined ball joint mounting help support consistent suspension geometry. The assembly includes rubber bushings and a pre-installed ball joint to simplify service on the specified applications. This part cross-references MOOG Chassis Products (e.g., RK623786) for the same application.

For Tesla S and Tesla X front suspension repair, this assembly addresses wear at the control arm, bushings, and ball joint interface while maintaining OE-style fitment for the listed model years. The Dorman 520-079 is a practical replacement choice when restoring front-end control and steering response on these Tesla applications.

Common Problems This Part Can Address

  • Clunking or knocking from the front suspension
  • Excessive play from a worn ball joint
  • Cracked, torn, or deteriorated control arm bushings
  • Uneven tire wear related to suspension looseness
  • Reduced directional stability during braking or cornering

Installation Notes and Tips

Verify the front left lower forward position before installation and confirm vehicle year and model against the listed fitment. Inspect adjacent suspension components, fasteners, and alignment settings during service. Because the ball joint is already installed, this assembly is suited to a complete control arm replacement rather than a separate joint-only repair.

Quality Assurance

Dorman evaluates this suspension control arm and ball joint assembly through an industry-focused validation process to support proper ride quality, stable tracking, and predictable suspension behavior on the specified Tesla applications.
