Applications and Problem Resolution

• Replaces worn or damaged suspension control arms on Mercedes-Benz CLS and E-Class AMG models
• Addresses issues with suspension noise or looseness caused by failing ball joints or bushings
• Improves vehicle handling and steering response by restoring proper suspension geometry
• Prevents premature tire wear related to suspension misalignment
• Eliminates corrosion-related failures common in older aluminum control arms

Installation Notes and Tips

Installation requires basic suspension tools and mechanical knowledge. The assembly comes with all necessary mounting hardware and bushings, but no grease fitting is included as the ball joint is pre-greased and non-greaseable. Ensure the vehicle is securely lifted and supported before removing the old control arm. Verify torque specifications for mounting bolts according to the vehicle manufacturer’s guidelines. Alignment check and adjustment after installation is recommended to maintain optimal handling and tire wear.
