Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat, stable surface.
Use jack stands for safety when lifting the vehicle.

2. Inspect and Replace Worn Suspension Components

Shock Absorbers/Struts:
- Remove the wheel corresponding to the clunking noise to access the suspension.
- Disconnect the shock absorber or strut from the top and bottom mounts.
- Inspect for leaks or noticeable damage.
- Replace with new shock absorbers/struts if necessary.
Control Arms and Bushings:
- Check the control arms and their bushings for wear.
- Remove the control arm bolts and disconnect the control arm from the chassis.
- Replace worn bushings and reassemble with new or refurbished components.

3. Reassemble and Reinstall Components

Reattach all suspension components securely, ensuring proper torque specifications are met (refer to the vehicle service manual for specific torque values).
Reinstall the wheel and lower the vehicle from the jack stands.
