Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Raise the Vehicle

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

3. Inspect and Tighten Suspension Components

Tools Required: Socket set, torque wrench
Inspect the control arms, sway bar links, and shock absorbers for wear.
Tighten any loose bolts to the manufacturer's specified torque settings.

4. Replace Worn Components

If any parts are found to be worn or damaged, replace them as follows:
- Shock Absorbers: Remove the old shock absorbers by unbolting them from the top and bottom mounts. Install new shocks by reversing the removal steps, ensuring proper torque on bolts.
- Sway Bar Links: Remove the old sway bar links by unbolting them from the sway bar and control arm. Install new links, ensuring they are securely tightened.

5. Reassemble and Lower Vehicle

Remove jack stands and lower the vehicle.
Double-check all components and fasteners for security before taking the vehicle off the jack.
