Solution

1. Preparation

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

2. Raise the Vehicle

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

3. Inspect and Replace Worn Components

Suspension Bushings:
- Remove the bolts securing the control arms or struts.
- Inspect the bushings for cracks or excessive wear.
- If damaged, replace with new bushings.
Sway Bar Links:
- Remove the bolts connecting the sway bar links to the sway bar and control arms.
- Inspect for wear; replace if necessary.
Struts/Shocks:
- Check for fluid leaks or physical damage.
- If worn, remove the strut assembly and replace with new struts/shocks.

4. Reassemble Components

Reattach all components using manufacturer-specified torque values.
Ensure all bolts and nuts are tightened securely.

5. Lower the Vehicle

Carefully remove jack stands and lower the vehicle back to the ground.
