Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, safety glasses, gloves
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery negative terminal for safety.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on where the noise originates).
Secure the vehicle with jack stands under the appropriate lifting points.

3. Inspect and Replace Components

a. Suspension Inspection

Sub-steps:
- Check struts or shock absorbers for leaks or damage.
- If defective, remove the strut assembly:
  - Tools Required: Spring compressor, socket set
  - Remove the bolts securing the strut to the steering knuckle and the top of the strut tower.
  - Compress the spring using a spring compressor and remove the strut from the vehicle.
- Replace with a new strut/shock if necessary, following manufacturer specifications.

b. Sway Bar Links and Bushings

Sub-steps:
- Inspect the sway bar links for wear.
- Remove any worn links:
  - Use a socket set to remove the bolts connecting the sway bar link to the sway bar and control arm.
  - Replace with new sway bar links.
- Check and replace bushings if degraded.

4. Reassemble and Lower Vehicle

Reinstall all components in the reverse order of removal, ensuring all bolts are torqued to specifications.
Lower the vehicle and reconnect the battery.
