Solution

1. Preparation

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

2. Raise the Vehicle

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

3. Inspect and Replace Suspension Components

Inspect Struts and Springs
- Remove the wheel to access the suspension.
- Check for wear or damage on struts and springs.
Replace Struts (if necessary)
- Remove the strut assembly by unscrewing the bolts connecting it to the hub and the upper strut mount.
- Install new struts, tightening bolts to the manufacturer's specifications (typically around 50-70 ft-lbs).

4. Replace Worn Bushings

Remove Control Arm or Relevant Suspension Component
- Detach the control arm or other affected components by removing the bolts.
- Replace worn bushings with new ones; use a bushing press if necessary.
- Reinstall the component and torque bolts as specified (typically around 30-50 ft-lbs).

5. Reassemble and Lower the Vehicle

Reinstall the wheel and lower the vehicle.
Tighten wheel lug nuts to the specified torque (usually around 80-100 ft-lbs).
