Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use jack stands to safely lift and support the vehicle.

2. Inspect and Remove Components

Remove the Wheel:
- Use a lug wrench to loosen and remove the lug nuts.
- Take off the wheel to access the suspension components.
Inspect the Suspension:
- Check the struts, shocks, control arms, and bushings for damage.
- If any component appears worn, proceed to replacement.

3. Replace Worn Components

Replacing Shocks/Struts:
- Remove the bolts securing the shocks/struts to the vehicle.
- Detach any associated components (e.g., sway bar link, brake line).
- Install the new shocks/struts by reversing the removal process.
- Torque the bolts to the manufacturer's specifications (usually found in the service manual).
Replacing Bushings:
- Use a bushing removal tool to extract the old bushings.
- Clean the mounting surface and install new bushings using a bushing press.
- Ensure proper alignment and seating.

4. Reassemble and Test

Reattach the wheels and torque the lug nuts to the specified value.
Lower the vehicle and perform a test drive to confirm the noise has been resolved.
