Solution

1. Preparation

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

2. Lift the Vehicle

Using the jack, lift the vehicle and secure it on jack stands.
Remove the wheels for better access to suspension components.

3. Inspect Suspension Components

Check struts and shocks for leaks or physical damage. Replace if necessary.
Inspect control arm bushings and sway bar links for wear or play. Replace any damaged components.
Use a pry bar to check for play in joints and bushings.

4. Tighten Loose Components

Tighten any loose bolts or nuts found during the inspection to the manufacturer's specified torque values.
Reinstall any fasteners that may have been removed during the inspection.

5. Reassemble and Lower the Vehicle

Reattach the wheels and lower the vehicle back to the ground.
Ensure all tools are removed from the work area before starting the vehicle.
