Direct Replacement Control Arm Assembly

Detailed Description
Part number 521-276 is a suspension control arm and ball joint assembly from Dorman for the front right upper position. It is built from steel with a casting/forged control arm design and includes the ball joint already installed, along with rubber bushings and mounting hardware. The pre-greased construction and bolt-in ball joint mounting help simplify service while maintaining the intended suspension geometry. This part number 521-276 is a direct-fit replacement for select Honda Passport, Isuzu Pickup, Isuzu Rodeo, and Isuzu Amigo applications.
Dorman designs this assembly as an OE-style replacement for vehicles that need a complete upper control arm solution rather than a separate arm and joint service. The threaded ball joint stud, 14 mm ball joint thread diameter, and 12.3 mm mounting hole diameter support proper installation on the listed applications. This part cross-references Monroe Shocks & Struts (e.g., RK621389) for the same application.
Common Repair Issues
- Excessive front-end looseness or wandering
- Uneven tire wear caused by worn suspension geometry
- Clunking or knocking from worn bushings or ball joint wear
- Reduced steering stability during braking or cornering
- Service needs where the control arm and ball joint are replaced together
Installation Notes
Verify the front right upper fitment before installation on the listed Honda Passport, Isuzu Pickup, Isuzu Rodeo, or Isuzu Amigo applications. Confirm mounting hole diameter, ball joint thread diameter, and suspension position against the original part. Because the ball joint is already installed, this assembly is suited to a complete replacement approach during suspension service.
Quality Assurance
Dorman subjects this assembly to an industry-leading evaluation process to help deliver consistent ride quality, directional stability, and predictable dynamics.
