OE-Style Suspension Replacement

This Dorman 521-056 assembly combines the control arm, ball joint, and bushings into one service part for rear suspension repair. The steel casting/forged construction, threaded ball joint stud, and press-in mounting style follow the OE layout for the Hyundai Azera and Hyundai Sonata rear right upper position. This part cross-references MOOG Chassis Products RK620646 for the same application.

Common Repair Symptoms

• Rear suspension clunking or looseness
• Uneven tire wear caused by worn rear control arm components
• Imprecise rear-end tracking or directional instability
• Excess play from deteriorated bushings or ball joint wear
• Noise over bumps from a fatigued upper control arm assembly

Installation Notes

Verify fitment by year, make, model, and rear right upper position before installation. Because the ball joint is already installed and the assembly is pre-greased, the part is ready for service once the mounting points are cleaned and inspected. Always confirm alignment after replacement, especially on Hyundai Azera and Hyundai Sonata rear suspension repairs. Dorman 521-056 is also listed under common interchange references for this application, including 172286 and 182286.

Quality Assurance

Dorman uses an industry-focused evaluation process for this suspension assembly to help support consistent ride behavior and suspension control. The part is built as a direct replacement for specific OE applications and is intended to match the original mounting and function requirements of the vehicle platform.
