Detailed Description

Dorman 522-587 is a suspension control arm and ball joint assembly engineered as a direct OE replacement for the front left upper position on the 1989-1990 Mitsubishi Van. The aluminum control arm, rubber bushings, and installed ball joint work together to restore suspension geometry and steering response on the Mitsubishi Van platform. This part number 522-587 is a practical choice when replacing worn upper control arm components on the front suspension.

This part cross-references Monroe Shocks & Struts (e.g., RK621394) for the same application.

What It Helps Address

  • Front-end looseness or wandering caused by worn control arm components
  • Clunking or knocking from deteriorated bushings or ball joint wear
  • Uneven tire wear related to suspension geometry issues
  • Reduced directional stability during braking or cornering
  • Restoring OE-style suspension movement on the Mitsubishi Van

Installation Notes and Tips

Fits 1989-1990 Mitsubishi Van, front left upper. Verify the press-in ball joint style, threaded stud type, and mounting dimensions before installation. The assembly is pre-greased and includes mounting hardware, which supports a straightforward replacement process. Because this is a non-adjustable control arm, proper alignment should be checked after installation.

Quality Assurance

Dorman uses an industry-focused evaluation process for this suspension assembly to support consistent ride quality, directional stability, and predictable dynamics. The design follows OE-style replacement requirements for the specified Mitsubishi Van applications.
