Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, and flashlight.
Ensure the vehicle is on a flat surface and engage the parking brake. Disconnect the battery if necessary.

2. Lift the Vehicle

Use the 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

Check struts and shocks for leaks:
- Look for oil around the strut body.
- Push down on the vehicle and release; it should return smoothly without excessive bouncing.
Inspect stabilizer links and bushings:
- Use a pry bar to check for excessive play in the links.
- Replace any worn or broken components.

4. Tighten Loose Components

Inspect all bolts in the suspension system for tightness.
Use the torque wrench to tighten them to manufacturer specifications (refer to service manual for specific torque values).

5. Replace Worn Parts

If any worn parts are found (e.g., struts, shocks, stabilizer links), replace them with OEM or quality aftermarket parts.
Ensure all new parts are installed correctly and torqued to specifications.
