Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and engage the parking brake.
  • Wear safety glasses and gloves for protection.
2. Lift the Vehicle
  • Use a hydraulic jack to lift the vehicle at the designated lift points.
  • Secure the vehicle with jack stands to ensure stability.
3. Inspect and Replace Components

A. Suspension Components

  • Inspect Struts/Shocks:

    • Remove the tires for better access.
    • Check for signs of fluid leakage around struts/shocks.
    • If damaged, proceed to replace.
  • Replace Struts/Shocks:

    • Remove the top and bottom mounting bolts using a socket set.
    • Install new struts/shocks, tightening bolts to manufacturer's specifications (typically 32-45 ft-lbs).

B. Sway Bar and Bushings

  • Inspect Sway Bar:

    • Check for bushings deterioration.
    • Remove sway bar links if needed.
  • Replace Bushings:

    • Remove old bushings using a bushing tool or press.
    • Install new bushings and reassemble sway bar links, ensuring proper torque (typically 20-25 ft-lbs).
4. Reassemble and Lower the Vehicle
  • Reinstall tires and torque lug nuts to the manufacturer's specification (typically 80-100 ft-lbs).
  • Carefully lower the vehicle from the jack stands and jack.
5. Final Checks
  • Perform a test drive to ensure the popping sound is resolved.
  • Inspect all replaced components for proper installation.
