Warning Lights: The dashboard displays warning lights related to the steering system.
Fluid Leaks: Presence of power steering fluid on the ground under the vehicle.

Step 1: Visual Inspection

Tools Required: None required for the initial inspection.
Procedure:

Step 3: Listen for Noises

Tools Required: None.
Procedure:
1. Start the engine and turn the steering wheel from lock to lock.
2. Listen for any abnormal noises such as whining, which could indicate a failing power steering pump or low fluid.

Step 4: Check for Steering Response
