Solution

1. Preparation

Gather tools including a socket set, jack stands, and a torque wrench.
Ensure the vehicle is parked on a level surface and turn off the ignition.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle depending on where the noise is originating.
Secure the vehicle with jack stands to ensure safety.

3. Inspect Suspension Components

Examine the strut assemblies for leaks or damage.
Check the lower control arms and bushings for wear; replace if cracked or deteriorated.
Inspect the sway bar links for looseness or damage and replace if necessary.

4. Replace Worn Components

If struts are found to be leaking or damaged, proceed to replace them:
- Remove the wheel using a socket set.
- Unbolt the strut from the lower control arm and top mount.
- Install the new strut, ensuring it is properly torqued to factory specifications.
Replace any worn bushings or sway bar links as needed.

5. Reassemble and Lower Vehicle

Reattach the wheel and tighten the lug nuts to the manufacturer’s specified torque.
Lower the vehicle back to the ground.
