How should you inspect the bus's axles?

Inspecting the bus's axles involves checking for signs of wear or unevenness, particularly on the tires. This is crucial because uneven tire wear can indicate alignment issues or that the axles are not functioning properly. Properly functioning axles help maintain even distribution of weight and vehicle stability, so observing wear on the tires can provide vital clues about the overall condition of the axles. Recognizing these signs allows for early detection of potential problems, ensuring safety and efficiency in the vehicle's operation.

While other aspects of axle inspection, like verifying lubrication, checking for rust, or assessing alignment, are also important, they do not directly address the first observable effect of axle issues—tire wear. Therefore, noticing signs of wear on the tires serves as an essential first step in axle inspection, highlighting the importance of this choice.
