What It Helps Fix

• Steering wander or reduced directional stability
• Front-end vibration related to worn bushings or ball joint wear
• Suspension noise during braking, turning, or road impacts

Installation Notes and Tips

Install this assembly at the front right lower position only on the listed applications. Because the ball joint is press-in and the stud is threaded, proper suspension service tools and a professional alignment are recommended after installation. Verify all mounting points, fasteners, and surrounding suspension components for wear before returning the vehicle to service. Dorman 526-634 is a direct replacement part for the confirmed fitment shown here.
