Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Replace Suspension Components

Lift the Vehicle
- Use a hydraulic lift or jack stands to safely elevate the vehicle.
- Ensure you secure the vehicle with jack stands for safety.
Remove Wheel
- Use a socket set to remove the wheel lug nuts and take off the wheel for better access to the suspension components.
Inspect Suspension Parts
- Check the struts and shocks for leaks or damage.
- Inspect control arms for any visible cracks or damage.
- Examine bushings for signs of wear or cracking.
Replace Damaged Components
- If any components are found to be damaged (e.g., struts, shocks, control arms), remove them using the appropriate socket sizes and replace them with new parts.
- Torque the new components to the manufacturer's specifications.

3. Reassemble

Reinstall Wheel
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle back to the ground and then torque the lug nuts to the recommended specification.
Test Drive
- Drive the vehicle over bumps to verify that the popping sound has been resolved.
