Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and ensure the engine is off.
Safety warning: Wear protective gear and ensure the vehicle is securely supported on jack stands.

2. Inspect Suspension Components

Remove the wheel on the affected side to access the suspension.
Inspect struts, shocks, control arms, and bushings for signs of wear or damage.
Check for any broken or loose components that may cause clunking noises.

3. Tighten or Replace Components

If any bolts or nuts are found loose, tighten them to manufacturer specifications using a torque wrench.
If any components are damaged (e.g., bushings, struts), remove the damaged part:
- Use a socket set to remove bolts securing the component.
- Replace with new parts, ensuring proper alignment before tightening.
Reinstall and torque bolts to specified values.

4. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Perform a test drive to verify that the noise has been eliminated.
