Solution

1. Preparation

Tools Required:
- Floor jack
- Jack stands
- Wrench set
- Torque wrench
- Inspection mirror
Safety Warnings:
- Ensure the vehicle is on a level surface before lifting.
- Always use jack stands when working underneath the vehicle.

2. Remove Wheel

Loosen the lug nuts on the front or rear wheel where noise is present.
Lift the vehicle with the floor jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Suspension Components

Inspect struts and shocks for leaks and physical damage.
Check bushings and mounts for wear or cracking.
Look for any loose or damaged hardware, such as bolts and nuts.

4. Replace Worn Components

If any components are found to be worn or damaged, replace them as necessary:
- Struts/Shocks: Remove the old unit by unbolting it from the assembly and install the new unit using the manufacturer's torque specifications.
- Bushings: Press out the worn bushings and install new ones using a bushing tool.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Perform a test drive to verify that the noise is eliminated.
