Solution

1. Preparation

Gather necessary tools and parts.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to gain access to the suspension components.

2. Inspect and Replace Components

Inspect Shock Absorbers/Struts:
- Check for signs of fluid leakage or physical damage.
- If damaged, remove the strut assembly using a socket set and replace with new components.
Check Control Arms and Bushings:
- Inspect control arms for cracks or excessive wear on bushings.
- If bushings are worn, press out old bushings and install new ones using a bushing tool.
Wheel Bearings:
- If wheel bearings are found to be loose or noisy, remove the hub assembly using a hub puller.
- Replace the bearings and reassemble according to manufacturer specifications.

3. Reassemble and Test

Reinstall the wheel and lower the vehicle off the jack stands.
Tighten all suspension bolts to the specified torque settings.
Test drive the vehicle to ensure the noise has been resolved.
