Detailed Description
Dorman 527-521 is engineered as an OE-style suspension control arm assembly for Tesla 3 and Tesla Y models in the front left lower rearward location. The assembly includes the ball joint, bushings, and mounting hardware, and it arrives pre-greased with a grease fitting for serviceability. Its steel construction and casting/forged control arm design support consistent suspension geometry, while the machined ball joint mounting and threaded stud help maintain secure fitment. This part cross-references MOOG Chassis Products RK623778 for the same application.
Common Repair Symptoms
- Clunking or knocking from the front suspension
- Loose or imprecise steering feel
- Uneven tire wear caused by worn suspension joints
- Directional instability during braking or lane changes
- Excess play from a worn control arm or ball joint
Installation Notes
Verify vehicle year, model, and front left lower rearward position before installation. Inspect adjacent suspension components, alignment angles, and fasteners during replacement. Because this assembly includes a pre-installed ball joint and bushings, it is suited for replacing a worn OE unit in one service operation. After installation, a professional wheel alignment is recommended to restore suspension geometry.
