What steering issue may indicate a problem with an MWS apparatus?

If the steering wheel can rotate more than 10 degrees without the front tires moving, this indicates a significant problem with the steering mechanism or linkage in a Mobile Water Supply (MWS) apparatus. In a properly functioning steering system, the movement of the steering wheel should directly correspond to the movement of the front tires. If there is excessive free play before the tires respond, it suggests a lack of connection or adjustment issues within the steering components, such as worn tie rods, a loose pitman arm, or malfunctioning steering gear. This can compromise the handling and safety of the apparatus, making it challenging for the operator to maintain control of the vehicle, especially in emergency situations where precise steering is crucial.

Other symptoms like tightness or restriction in the steering, an off-center steering wheel, or grinding noises can also signal issues; however, the specific problem of excessive free play directly relates to fundamental steering mechanics, impacting both safety and vehicle maneuverability more critically than the other options presented.
