Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for added safety.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on where the noise is suspected to originate.
Secure the vehicle with jack stands.

3. Inspect Suspension Components

Struts and Shocks:
- Remove the wheel to access the strut assembly.
- Check for visible leaks or damage on the shock absorbers and struts.
Bushings:
- Inspect control arm bushings for signs of cracking or deterioration.
- If bushings are worn, proceed to replace them.

4. Replace Damaged Components

If any strut, shock, or bushing is found to be defective:
- Strut Replacement:
  - Remove the top mounting bolts and lower bolts securing the strut.
  - Replace the strut with a new one, ensuring proper alignment with the mounting points.
  - Torque the bolts to manufacturer specifications (refer to service manual for exact torque values).
- Bushing Replacement:
  - Remove the control arm if necessary for bushing access.
  - Use a bushing removal tool to extract the old bushing.
  - Install the new bushing, ensuring it is seated correctly.

5. Reassemble and Lower the Vehicle

Reinstall the wheel and ensure all lug nuts are torqued to specifications.
Lower the vehicle back to the ground and remove wheel chocks.

6. Test Drive

Take the vehicle for a test drive over bumps to confirm the popping noise has been resolved.
