Solution

1. Preparation

Tools Required: Jack, jack stands, tire iron, flashlight.
Park the vehicle on a level surface and engage the parking brake.

2. Lift Vehicle

Use the jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands for safety.

3. Inspect Suspension Components

Control Arms: Check for cracks or rust. Inspect the bushings for wear or deterioration.
Struts and Shocks: Look for oil leakage or physical damage. Press down on the corners of the vehicle and observe if it rebounds excessively.
Ball Joints: Check for cracks in the rubber boots and feel for play by moving the wheel side to side while holding the control arm.
Sway Bar Links: Inspect for wear or looseness.

4. Check for Loose Components

Use a pry bar to gently move components, identifying any excessive movement that indicates worn parts.

5. Reassemble and Lower Vehicle

Once inspections are complete, remove jack stands and lower the vehicle safely.
Re-torque any bolts that were loosened during inspection to manufacturer's specifications.
