Detailed Description

This Dorman suspension control arm and ball joint assembly is engineered for 2008-2013 Infiniti G37 rear left upper applications and 2014-2015 Infiniti Q60 rear left upper applications. The Dorman 522-571 combines the control arm, bushings, and ball joint into one replacement assembly to restore suspension geometry and help maintain directional stability and predictable ride dynamics. Its aluminum casting/forged construction supports light-duty suspension use while the pre-greased ball joint helps reduce initial friction at installation.

This part cross-references Beck/Arnley 102-7650 and Mevotech Supreme CMS301192 for the same application.

What It Helps Fix

• Clunking or knocking from the rear suspension
• Excessive play in the rear left upper control arm assembly
• Uneven rear tire wear caused by worn suspension joints
• Loose or unstable rear-end handling
• Suspension noise from deteriorated bushings or ball joint wear

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and rear left upper position before installation. The ball joint uses a press-in mounting style with a threaded stud, so proper suspension service tools and alignment procedures are recommended after replacement. Confirm mounting hole diameter and hardware fitment during installation to ensure correct seating and torque.

Quality Assurance

Dorman uses an industry-focused evaluation process for this replacement assembly to support smooth ride quality, directional stability, and predictable suspension response. The part number 522-571 is built as an OE-style replacement for select Infiniti G37 and Q60 rear suspension applications.
