Solution

1. Preparation

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

2. Raise the Vehicle

Use a jack to lift the front and/or rear of the vehicle as needed.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Components

Suspension Components:
- Check struts/shocks:
  - If leaking or damaged, remove the old strut/shock by unscrewing the mounting bolts and lift it out.
  - Install new strut/shock by aligning it in place and tightening to manufacturer torque specifications (usually around 15-25 ft-lbs).
- Check sway bar links:
  - If worn out, detach the old sway bar link and replace it with a new one, ensuring to torque to specifications (typically around 20-30 ft-lbs).

4. Reassemble and Lower the Vehicle

Reattach any removed components securely.
Carefully lower the vehicle and remove jack stands.
Tighten all lug nuts to the specified torque (usually 80-100 ft-lbs).

5. Test Drive

Conduct a test drive over bumps to ensure the noise has been resolved.
