What It Helps Address

• Front-end clunking or knocking from worn suspension joints
• Excessive play in the upper rearward control arm area
• Uneven tire wear caused by suspension looseness
• Imprecise steering feel on Audi and Porsche front suspension systems
• Corrosion-related replacement needs on exposed suspension components

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and front left upper rearward position before installation. Because this assembly includes the ball joint and bushings, it is suited for replacing worn suspension pivot points in one service step. After installation, a professional wheel alignment is recommended to confirm suspension angles and steering tracking.
