What action is recommended to inspect for steering binding?

Turning the wheel to full lock in each direction is a recommended action to inspect for steering binding because it allows the inspector to evaluate the entire range of motion of the steering system. When the steering wheel is turned to its limits, it can reveal whether any binding or resistance occurs, indicating potential issues such as worn components, misalignment, or inadequate lubrication within the steering assembly. This method gives a clear indication of how the steering feels and whether any obstruction or friction is present, which is essential for ensuring safe vehicle operation.

Other actions, while significant in different contexts, do not directly assess the issue of steering binding in the same comprehensive manner. For instance, lubricating joints may help if binding is due to lack of lubrication, but it does not test for binding itself. Inspecting the power steering pump could identify a lack of hydraulic pressure, but it does not directly assess the mechanical components that could be causing binding. Similarly, replacing the steering rack without a thorough inspection could be unnecessary and would miss the opportunity to determine the cause of any binding issues effectively.
