Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on where the noise originates.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Worn Components

Inspect Shocks/Struts:
- Remove the wheel to access the shocks/struts.
- Check for signs of oil leakage or physical damage.
- If damaged, remove the shock/strut using a socket set to unbolt it from the top and bottom mounts. Replace with a new, OEM-quality component.
Replace Bushings:
- Inspect all bushings in the suspension system for wear.
- Use a bushing removal tool to extract old bushings.
- Install new bushings using a press or appropriate tool, ensuring they are seated properly.
Check Sway Bar Links:
- Inspect sway bar links for play and wear.
- Remove and replace any worn links with new OEM parts.

4. Reassembly

Reattach any components previously removed, ensuring all bolts are torqued to manufacturer specifications.
Reinstall the wheel and lower the vehicle back to the ground.

5. Final Checks

Conduct a visual inspection to ensure all tools and parts are accounted for.
Clear any debris from around the suspension components.
