Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, engage the parking brake, and use wheel chocks for safety.
Disconnect the battery if needed for electrical components.

2. Raise the Vehicle

Use a jack to lift the vehicle and securely place jack stands under the frame.
Remove the wheels for better access to suspension components.

3. Inspect and Replace Components

Strut Inspection:
- Remove the strut assembly by loosening the top mount bolts and the lower strut bolts.
- Inspect the strut for leakage or damage; replace if necessary.
Bushing and Mount Inspection:
- Check control arm bushings and strut mounts for wear or cracks. Replace any that show signs of deterioration.
Sway Bar Link Replacement:
- Disconnect the sway bar links from the sway bar and control arms using a socket set.
- Replace with new links if they are worn or damaged.

4. Reassemble Suspension

Reinstall the strut assembly, ensuring that all bolts are torqued to the manufacturer's specifications.
Reattach the sway bar links and ensure they are tight.
Replace the wheels and torque the lug nuts to the specified value.

5. Lower Vehicle and Test

Carefully lower the vehicle back to the ground.
Reconnect the battery if it was disconnected.
Test drive the vehicle to confirm that the noise has been resolved.
