Why is it important to check for missing nuts, bolts, and cotter keys in the steering system?

The focus of checking for missing nuts, bolts, and cotter keys in the steering system is primarily about safety and functionality. Ensuring that all components are present and secure is crucial because any missing part can compromise the integrity of the steering system. If the steering is loose or malfunctions due to absent components, it could lead to a total loss of vehicle control, which poses a significant safety risk to the driver and others on the road. Regular inspections help prevent such catastrophic failures and ensure that the steering mechanisms function as intended. This not only contributes to safe driving but also enhances the overall reliability of the vehicle.
