Solution

1. Preparation

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

2. Raise the Vehicle

Use a 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 Replace Components

Inspect Struts/Shocks:
- Check for oil leakage or physical damage.
- If damaged, remove the strut assembly by loosening the bolts at the top and bottom.
- Replace with new struts/shocks, ensuring to torque bolts to manufacturer specifications.
Check Control Arms and Bushings:
- Inspect the control arms for cracks or bent shapes.
- Replace any worn bushings or control arms. Remove the bolts holding the control arm and install new parts.
- Torque the bolts to the manufacturer’s specifications.
Examine Stabilizer Links:
- Check the stabilizer links for wear and play.
- Replace if necessary by removing the old links and installing new ones, ensuring the nuts are properly torqued.

4. Reassemble and Lower Vehicle

After all necessary components are inspected and replaced, reassemble any parts removed.
Lower the vehicle back to the ground and remove jack stands.
