To check for binding in the steering, what action should be taken?

To check for binding in the steering system, turning the wheel to full lock in each direction is the most effective method. This action allows the inspector to evaluate the full range of motion of the steering system and to identify any restrictions or irregularities that may indicate binding. When the wheel is turned to its maximum position, any signs of resistance, noise, or lack of smoothness can reveal potential issues such as problems with the power steering mechanism, a misalignment, or damage to the steering components.

While other options like rotating the wheel side to side can provide information on general movement, it doesn't provide the same clarity about potential binding as the full lock maneuver does. Checking fluid levels and inspecting the steering column are important for overall system maintenance and safety but do not directly diagnose binding issues. Therefore, turning the wheel to full lock is a targeted approach that directly assesses the functionality of the steering.
