Detailed Description

This suspension control arm assembly is built for Toyota front suspension service where OE-style geometry and consistent steering response matter. Dorman 521-628 uses a steel control arm with rubber bushings and an installed ball joint to support stable alignment behavior and controlled suspension movement. It is a direct replacement for the original equipment on select 1986-1995 Toyota 4Runner, 1986-1995 Toyota Pickup, and 1993-1998 Toyota T100 front right upper applications. This part cross-references MOOG Chassis Products RK620680 for the same application.

What It Helps Address

• Excessive front-end looseness or wandering
• Clunking or knocking from worn upper control arm components
• Uneven tire wear related to suspension wear
• Reduced directional stability during braking or cornering
• Ball joint or bushing wear in the front right upper suspension

Installation Notes and Tips

Install this assembly in the front right upper position only on the listed Toyota applications. Verify fitment by year, make, model, and suspension position before installation. Because the ball joint is already installed and the assembly is pre-greased, it is ready for suspension service once the mounting points are inspected and prepared. After installation, a professional wheel alignment is recommended to confirm proper suspension geometry.
