The arm measures 262.5 mm in length, matching factory specifications for proper suspension geometry. Note that this control arm does not include a ball joint or mounting hardware, allowing for flexibility in installation depending on your vehicle’s setup.

Common Suspension Issues Addressed by This Control Arm

• Worn or damaged control arm bushings causing clunking noises
• Misalignment leading to uneven tire wear
• Reduced handling stability and steering response
• Corrosion or structural fatigue in original suspension components
• Vibration and harshness transmitted through the suspension

Installation Notes and Tips

When installing the Dorman 524-563 suspension control arm, ensure the vehicle is securely lifted and supported. Remove the old control arm carefully, noting the position of bushings and mounting points. Since the ball joint is not included, inspect the existing ball joint for wear and replace if necessary. Use appropriate tools to press in the bushing end and torque all fasteners to manufacturer specifications. Professional alignment after installation is recommended to maintain proper suspension geometry and tire wear.
