Solution

1. Preparation

Tools Required: Jack stands, socket set, torque wrench, mechanic's stethoscope, multimeter (if applicable).
Ensure the vehicle is on a flat surface and secure with the parking brake engaged.

2. Replace Worn Components

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the wheel to access the suspension components.
3. Inspect and identify the component(s) that need replacement (e.g., struts, bushings).
4. For strut replacement:
  - Disconnect the strut from the steering knuckle and the top mount.
  - Remove the old strut and replace it with a new one.
  - Reinstall the strut, ensuring all bolts are torqued to the manufacturer's specifications.
5. For bushing replacement:
  - Remove the control arm or component with the worn bushing.
  - Press out the old bushing and press in the new bushing using a bushing tool.
  - Reinstall the control arm and torque the bolts accordingly.

3. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Tighten lug nuts to the specified torque.
Perform a test drive to ensure the noise has been eliminated.
