Common Problems It Can Help Address

• Excessive play in the rear upper control arm pivot
• Clunking or knocking from worn suspension bushings
• Imprecise rear suspension response
• Uneven bushing wear from age, heat, and road exposure
• Loss of OE-style control arm support on high-mileage vehicles

Installation Notes and Tips

Verify rear upper fitment by year, make, and model before installation. Inspect the control arm, mounting surfaces, and surrounding suspension components for wear or damage before pressing in the new bushings. Because mounting hardware is not included, reuse or source the required hardware separately if your application calls for it. Proper alignment is recommended after suspension work is completed.
