Installation Notes and Tips

Install in the rear right upper forward suspension position only. This control arm does not include a ball joint, and mounting hardware is not included. Because the ball joint uses a press-in mounting type, proper suspension tools and alignment service are recommended after installation. Verify vehicle application by year, model, and position before ordering.
