Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, and a creeper.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use a jack to raise the vehicle and secure it with jack stands.
Remove the wheels if necessary for better access to suspension components.

3. Inspect and Replace Components

Suspension Components:
- Check struts and shocks:
  - If they are leaking or damaged, remove the old struts/shocks.
  - Install new OEM or high-quality aftermarket struts/shocks, ensuring proper alignment with the mounting points.
  - Torque the bolts to manufacturer specifications.
Sway Bar Links:
- Inspect sway bar links:
  - If worn or damaged, remove and replace with new sway bar links.
  - Ensure all fasteners are torqued to specifications.

4. Reassemble and Lower Vehicle

Reinstall wheels if removed, and torque lug nuts to specifications.
Carefully lower the vehicle back to the ground.

5. Final Checks

Conduct a bounce test again to ensure proper functioning of the suspension.
Check for any remaining loose parts around the suspension and exhaust systems.
