Fitment Details

Compatible With 2009-2014 Hyundai Genesis, front right upper rearward, and 2011-2013 Hyundai Equus, front right upper rearward. Also fits 2014 Hyundai Equus, front right upper rearward, to 2/04/14. This Dorman 521-742 is a direct-fit suspension control arm assembly for these specific applications.

This part cross-references Delphi TC7408 for the same application.

What It Helps Address

• Front-end looseness or wandering caused by worn suspension joints
• Clunking or knocking from a deteriorated control arm assembly
• Uneven steering response from worn bushings or ball joint wear
• Directional instability during braking or lane changes
• Excessive suspension play at the front right upper rearward mounting point

Installation Notes

Verify vehicle fitment by year, model, and position before installation. This assembly uses a press-in ball joint with a threaded stud and includes bushings and mounting hardware. Because the ball joint is already installed and the unit is pre-greased, installation can be streamlined compared with rebuilding the arm separately.

Quality Assurance

Dorman evaluates this replacement assembly through an industry-focused validation process to help maintain ride quality, stability, and consistent suspension behavior. It is engineered as a direct replacement for the original equipment on the listed Hyundai Genesis and Hyundai Equus applications.
