Detailed Description
This Dorman suspension control arm assembly combines the control arm, bushings, and ball joint into one service-ready component for the front left lower suspension position. The steel casting/forged arm uses rubber bushings and a press-in ball joint design to match the original suspension layout on select Mazda Protege vehicles. Dorman 520-879 is a practical OE-style replacement for drivers servicing worn front suspension components on 1995, 1996, 1997, and 1998 Mazda Protege models.
This part cross-references Mevotech Original Grade GS76103 and Mevotech Supreme CMS76103 for the same application.
Common Problems This Part Can Address
- Front-end clunking or knocking from a worn control arm or ball joint
- Loose or inconsistent steering feel
- Uneven tire wear caused by suspension wear
- Excessive play in the front left lower suspension
- Reduced directional stability during braking or cornering
Installation Notes and Tips
Install this assembly on the front left lower position only for the listed Mazda Protege applications. Verify the ball joint mounting style, stud type, and mounting hole dimensions before installation. Because the ball joint is already installed and the assembly is pre-greased, it is ready for suspension service once the old component is removed and alignment checks are completed.
Quality Assurance
Dorman uses an industry-focused evaluation process to validate fit, function, and suspension performance characteristics. The goal is to restore proper ride control, directional stability, and predictable handling behavior on the specified Mazda Protege applications.
