Maintenance

Coil springs generally require minimal maintenance once installed. However, regular inspection of your vehicle's entire suspension system is recommended as part of routine vehicle servicing. This includes checking for:

• Signs of corrosion or damage to the springs.
• Wear on associated components such as shocks, struts, bushings, and control arms.
• Proper alignment, especially if you notice uneven tire wear or changes in handling.

Addressing any issues promptly will help maintain the longevity and performance of your MOOG coil springs and the entire suspension system.

Troubleshooting

If you experience issues after installing your MOOG 81649 Coil Spring Set, consider the following common troubleshooting points:

• Uneven Ride Height or Sagging: Ensure the correct springs were installed for your specific vehicle model and year. Verify that all other suspension components (shocks, struts, bushings) are in good condition and not contributing to the issue. A post-installation alignment is critical.
• Unusual Noises (Squeaks, Clunks): Check for proper seating of the springs in their mounts. Inspect for any loose fasteners or contact between suspension components. Ensure spring insulators (if applicable) are correctly in place.
• Poor Handling or Steering: This often indicates an alignment issue. Even if new springs restore ride height, proper wheel alignment is essential for correct handling. Also, inspect other steering and suspension components for wear.

For persistent issues, consult a certified automotive technician.
