Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks for additional safety.

2. Raise the Vehicle

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

3. Inspect Suspension Components

Shocks/Struts
- Remove the wheel for access.
- Inspect for leaks or damage.
- Check mounting bolts for tightness; torque to manufacturer specifications if loose.
Sway Bar Links/Bushings
- Inspect for wear or damage.
- Replace if cracked or loose. Use a socket set for removal and installation.
Control Arms
- Check for cracked bushings or excessive play.
- Replace if needed; ensure to torque bolts to manufacturer specifications.

4. Replace Damaged Components

Install new components as necessary, ensuring all bolts are torqued to factory specifications.
For sway bar links, typically torque to 36 ft-lbs, and for strut mounts, refer to the specific service manual for values.

5. Reassemble and Lower Vehicle

Reinstall the wheel and lug nuts, tightening to the specified torque.
Lower the vehicle and remove wheel chocks.
