Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and a flashlight.
Ensure the vehicle is on a flat surface, and engage the parking brake.
Gather all necessary tools and parts before starting the repair.

2. Lift the Vehicle

Use the jack to lift the vehicle and secure it with jack stands.
Ensure all wheels are off the ground for access to the suspension components.

3. Inspect and Replace Components

Inspect Shocks/Struts:
- Check for oil leakage or damage to the struts/shocks.
- If damaged, remove the strut assembly using the socket set, noting the torque specifications for reinstallation.
- Replace with new shocks/struts as needed.
Check and Replace Bushings:
- Using a pry bar, check the bushings on control arms and sway bar links for cracks or excessive play.
- If necessary, remove the control arm or sway bar link, and replace the worn bushings with new ones.

4. Tighten Loose Hardware

Check all bolts and nuts on the suspension components for tightness.
Use a torque wrench to ensure all hardware is tightened to the manufacturer’s specifications.

5. Reassemble and Lower Vehicle

Reinstall any removed components, ensuring all are secured properly.
Lower the vehicle from the jack stands and perform a final check of the suspension area.
