Solution

1. Preparation

Tools Required: Jack, jack stands, pry bar, torque wrench, socket set, inspection mirror.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Raise the Vehicle

Use a jack to lift the vehicle and securely place it on jack stands.
Ensure all four corners are elevated for a complete inspection.

3. Inspect Shock Absorbers and Struts

Sub-steps:
- Look for signs of leaking fluid on the shock bodies.
- Check for dents or signs of physical damage.
- Press down on the strut to see if it rebounds quickly without excessive bouncing.

4. Examine Control Arms and Bushings

Sub-steps:
- Use a pry bar to apply pressure to the control arms and look for excessive movement in the bushings.
- Check for any cracks or signs of wear in the rubber bushings.
- Inspect the ball joints for wear by moving them up and down, ensuring they are tight.

5. Check Sway Bar Links

Sub-steps:
- Inspect the sway bar links for any signs of damage or looseness.
- Gently shake the links to check for excessive play.

6. Reassemble and Lower the Vehicle

After inspection and any necessary repairs, remove the jack stands and carefully lower the vehicle back to the ground.
