Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before working underneath it.

3. Inspect and Replace Components

Inspect Shock Absorbers/Struts:
- Check for leaks or physical damage.
- If damaged, remove the old shocks/struts using a socket wrench.
- Install new shocks/struts and torque to the manufacturer’s specifications.
Check Control Arms and Bushings:
- Inspect for cracks or excessive play.
- If worn, unbolt the control arm from the vehicle.
- Replace the bushings if necessary, then reinstall the control arm and torque bolts to specifications.
Tighten Loose Bolts:
- Check and tighten all suspension-related bolts and nuts.

4. Reassemble and Lower the Vehicle

Remove jack stands and lower the vehicle carefully.
Recheck all components for secure installation.

5. Final Checks

Conduct a wheel alignment if necessary.
Make sure all components are functioning correctly before test driving.
