Common Repair Symptoms

• Rear suspension clunking or knocking over bumps
• Uneven tire wear caused by worn control arm or ball joint components
• Loose or unstable rear-end handling
• Excessive play in the rear left upper suspension linkage
• Noise from deteriorated bushings or a worn dust boot

Installation Notes

Verify the rear left upper position before installation and compare the original arm, ball joint style, and mounting points to the removed component. Because the ball joint is press-in and the stud is threaded, proper suspension service tools and torque procedures are important for correct installation. Confirm fitment on the vehicle by year, model, and position before assembly.
