Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

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

3. Inspect Suspension Components

Visually inspect the struts or shocks for any signs of leakage or damage.
Check control arms and tie rod ends for play or wear.
Examine the bushings for cracks or deterioration. Replace any worn components.

4. Tighten Loose Bolts

Use a socket set to tighten any loose bolts on the suspension components, including strut mounts and control arm bolts, to manufacturer specifications (typically around 70-80 ft-lbs for most components, but check specifications for the specific model).

5. Replace Damaged Components

If any parts are found to be damaged or excessively worn, replace them with new parts. Follow manufacturer instructions for proper installation.
Ensure all new components are torqued to the specified values.

6. Reassemble and Lower the Vehicle

Remove jack stands and carefully lower the vehicle using the jack.
Ensure all tools are removed from under the vehicle before lowering.
