Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the battery before working on electrical components.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Suspension Components

A. Visual Inspection

Check for damaged or worn-out components like struts, shocks, sway bar links, and control arms.

B. Replace Worn Components

If any components are damaged, proceed with replacement:
1. Remove the Wheel:
  - Use a socket set to remove the lug nuts and take off the wheel.
2. Remove Old Component:
  - Unbolt the strut or shock from the upper and lower mounts using the appropriate socket.
  - Remove sway bar links if they are damaged.
3. Install New Component:
  - Position the new strut or shock in place and bolt it securely using torque specifications from the service manual (typically around 40-60 ft-lbs).
  - Reattach sway bar links ensuring they are tight.

3. Reassemble and Test

Reinstall the wheel and tighten lug nuts to the manufacturer’s specifications (usually about 80-100 ft-lbs).
Lower the vehicle and reconnect the battery.
Conduct a test drive to verify the noise has been resolved.
