Detailed Description

This Dorman suspension control arm and ball joint assembly is built for Tesla Model 3 and Tesla Model Y front left upper applications where the original arm can crack or separate from the steering knuckle. The upgraded boxed steel arm replaces the factory plastic-style design with a stronger metal construction, while the open design eliminates the plastic cap that can trap moisture around the joint. The result is a more durable OE-style repair for drivers looking to restore front suspension integrity on a Tesla Model 3 or Tesla Model Y. Part number 527-513 is precision engineered for factory fit and serviceability.

This part cross-references MOOG Chassis Products RK623788 for the same application.

What It Helps Fix

• Front-end creaking from moisture trapped around the ball joint
• Cracking in the upper left control arm
• Separation between the control arm and steering knuckle
• Ball joint wear caused by corrosion and contamination
• Loose or noisy front suspension operation

Installation Notes and Tips

Install on the front left upper position only. Verify Tesla Model 3 or Tesla Model Y year and suspension configuration before ordering. Because this assembly includes a machined ball joint with a pinch-style stud, follow factory service procedures for removal and torque specifications during installation. Inspect the steering knuckle, adjacent bushings, and mounting points for wear before completing the repair.

Dorman designs this OE FIX assembly to address known factory failure points with a stronger steel arm, corrosion-resistant coating, and a direct-fit layout. Part number 527-513 is manufactured to match factory dimensions while improving durability for long-term service on Tesla Model 3 and Tesla Model Y front suspension repairs.
