What is the proper procedure for checking the steering mechanism?

• A. Inspect for free movement and no excessive play in the steering wheel
• B. Ensure all steering fluid levels are adequate
• C. Check the power steering functionality only
• D. Verify that the steering wheel is not too loose

Answer: (A)

To properly check the steering mechanism, it is essential to inspect for free movement and to ensure there is no excessive play in the steering wheel. This step is crucial because the steering system directly impacts the vehicle’s handling and safety. If there is excessive play, it could indicate issues such as worn components or inadequate adjustments, which can compromise the driver's ability to control the bus effectively.

Checking for free movement means ensuring that the steering wheel doesn’t stick or face resistance when being turned, allowing for smooth and precise steering response. This is vital for maneuverability and safety, particularly when navigating traffic or making quick directional changes.

In contrast, while ensuring adequate steering fluid levels is important for the overall functioning of the power steering system, it does not directly address the immediate physical condition of the steering mechanism itself. Checking only the power steering functionality can overlook mechanical wear that might exist independently of the fluid's condition. Evaluating whether the steering wheel is too loose is too vague and does not encompass the complete inspection necessary for safe operation, which requires comprehensive attention to both free movement and play.

Thus, the correct procedure, which emphasizes a thorough inspection for both movement and play, ensures that the steering system is in a reliable condition for safe driving.
