Detailed Description

This Dorman suspension control arm and ball joint assembly is engineered as an OE-style replacement for the rear left upper suspension position. The machined ball joint mounting, pinch-style stud, and regular light-duty suspension grade support consistent suspension geometry on vehicles such as the INFINITI QX60 and Nissan Pathfinder. Dorman 528-047 is pre-greased, includes the ball joint already installed, and uses a steel control arm with bushings to help maintain stable handling and controlled wheel movement. This part cross-references Nissan (e.g., 555023JA0A) for the same application.

What It Helps Address

• Clunking or knocking from the rear suspension
• Excessive play in the rear left upper control arm assembly
• Uneven rear suspension movement
• Directional instability during driving
• Worn ball joint or bushing-related suspension noise

Installation Notes and Tips

Confirm rear left upper fitment before ordering. This assembly uses a pinch-style ball joint stud and does not include mounting hardware, so reuse or source the correct hardware as needed. Because the ball joint is already installed, installation focuses on replacing the complete control arm assembly rather than servicing individual components. After installation, inspect alignment and suspension fasteners according to factory service procedures.

Quality Assurance

Dorman uses an industry-leading evaluation process to verify fit, function, and suspension performance characteristics for this replacement assembly. The result is a part intended to support smooth ride quality, directional stability, and predictable dynamics on confirmed applications.
