What components are part of the steering system in vehicle inspections?

The components that are part of the steering system in vehicle inspections include items like ball joints and the pitman arm. Ball joints are critical because they connect the steering knuckle to the control arms, allowing for smooth movement and stability while steering. The pitman arm is another essential component, as it transfers the motion from the steering gear to the linkage that directs the wheels. Proper inspection of these elements is crucial for ensuring that the steering system functions correctly, maintaining vehicle control and safety.

In contrast, the other options mention components from different systems. Brake shoes and drums are related to the braking system, which is entirely separate from steering. The crossover line and fuel line refer to fuel delivery and management, which are also not related to steering. Finally, air lines and glad hands pertain to the air brake system typically found in heavy-duty vehicles, which again do not have a direct role in the steering mechanism. Thus, the focus on ball joints and the pitman arm is essential for evaluating the effectiveness and safety of the steering system during vehicle inspections.
