OE-Style Suspension Replacement

This suspension control arm assembly is designed for vehicles that need a precise rear suspension repair without changing the original geometry. The steel casting/forged control arm, rubber bushings, and installed ball joint help maintain consistent alignment behavior and suspension movement. It is a practical replacement for a Subaru BRZ rear right upper control arm, Toyota GR86 rear right upper control arm, Toyota 86 rear right upper control arm, Scion FR-S rear right upper control arm, and select Subaru WRX, WRX STI, and Impreza rear right upper upper applications.

This part cross-references Delphi TC7644 and Mevotech Supreme CMS801181 for the same application. Part number 524-774 is also referenced in OE-style suspension repair searches for Subaru BRZ and Toyota GR86 rear suspension service.

What It Helps Repair

• Rear suspension looseness or instability
• Uneven tire wear caused by worn control arm bushings or ball joint wear
• Clunking or knocking from the rear suspension
• Imprecise directional control during cornering or braking
• Restoring OE suspension geometry after component wear

Installation Notes

Verify vehicle fitment by year, make, model, and rear right upper position before installation. This assembly uses two mounting holes, includes bushings, and does not include mounting hardware. Because the ball joint is already installed, replacement is streamlined compared with rebuilding the arm separately. After installation, a professional alignment is recommended to confirm suspension settings.

Quality Assurance

Dorman subjects this control arm and ball joint assembly to an industry-focused evaluation process to help deliver consistent ride quality, directional stability, and predictable handling characteristics. Part number 524-774 is built as a direct replacement solution for specific applications, including Subaru BRZ, Toyota GR86, and related rear suspension platforms.
