Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use jack stands to safely lift and support the vehicle.

2. Inspect Suspension Components

Sub-steps:
- Remove the front wheel using a socket set and impact wrench.
- Visually inspect the struts and shocks for leaks or damage.
- Check control arm bushings for wear or cracking.
- Ensure sway bar links are secure and intact.

3. Replace Worn Components

Sub-steps:
- If any components are found to be worn (e.g., shocks/struts), remove them using a socket set.
- Install new shocks/struts, ensuring to use the correct torque specifications (usually around 50-70 ft-lbs for strut bolts, but check the service manual for specifics).
- Replace any damaged bushings or sway bar links as necessary.

4. Reassemble and Lower Vehicle

Sub-steps:
- Reinstall the front wheel and torque the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).
- Lower the vehicle back to the ground and remove jack stands.

5. Final Inspection

Ensure all components are securely fastened and there are no remaining loose parts.
Perform a test drive to confirm the noise has been resolved.
