Built for OE-Style Suspension Service

This Dorman 522-625 assembly combines the control arm, ball joint, and bushings in one replacement unit for rear suspension service. The aluminum casting/forged arm is paired with a press-in, installed ball joint and rubber bushings to support consistent suspension movement and alignment stability on INFINITI QX50, Q60, EX37, G37, and EX35 rear left upper applications. This part cross-references Mevotech Supreme CMS801127 for the same application.

Common Problems This Part Can Address

• Rear suspension looseness or clunking from worn ball joint or bushings
• Uneven tire wear related to degraded rear upper control arm components
• Directional instability or wandering caused by suspension wear
• Excess play in the rear left upper suspension link
• Restoration of factory-style rear suspension geometry after component wear

Installation Notes and Tips

Verify vehicle fitment by year, model, and rear left upper position before installation. Because the ball joint is installed and the assembly is pre-greased, the unit is ready for suspension service once the original component is removed. After installation, a professional wheel alignment is recommended to confirm suspension geometry and steering stability.

Quality Assurance

Dorman evaluates this suspension control arm and ball joint assembly through an industry-focused validation process to support proper ride quality, directional stability, and predictable handling characteristics. The design follows direct-replacement OE-style requirements for the listed INFINITI applications.
