• Cleanliness: Keep the suspension area free from excessive dirt and debris, which can accelerate wear.

8. Troubleshooting Common Issues

If you experience any issues after installation, consider the following:

• Noise (Clunking/Rattling):
  • Check all mounting bolts (upper and lower) for proper torque.
  • Ensure sway bar links are properly connected and tightened.
  • Verify that no components are interfering with other parts of the suspension or chassis.
• Poor Handling/Uneven Ride:
  • Confirm that the correct strut assembly was installed for your vehicle model and side (if applicable).
  • Ensure a professional wheel alignment has been performed.
  • Inspect for any damaged or improperly installed components.
