What should be the status of joints in the steering arm inspection?

The status of the joints in the steering arm inspection should be that they are not loose or worn. This is crucial because if the joints are loose or have excessive wear, it can lead to steering instability, reduced control over the vehicle, and potentially dangerous driving conditions. Having properly maintained and secure joints ensures that the steering mechanism works as intended, providing safe maneuverability and responsiveness while driving.

In this context, the other options do not accurately reflect the desired condition of the steering arm joints. Loose or cracked joints would indicate a serious problem that could compromise vehicle safety. Strong and flexible joints would not be a definitive indicator of proper condition, as flexibility alone does not ensure stability. Regarding joints needing to be covered in grease, while lubrication is important for maintaining joint function and preventing wear, it does not address the fundamental requirement for the joints to be secure and free of defects.
