Show the correct answer
Correct answer
C. Louder operation of the power steering pump when maneuvering the steering wheel with the engine on.
Explanation
The question is about a symptom of too little power steering fluid in a bus. It is shown by louder operation of the power steering pump when you turn the steering wheel with the engine running - answer C.
The Road Traffic Act requires a vehicle to ensure easy and reliable use of the steering device. When there is too little fluid, the pump sucks in air, which you can hear as a whine or hum, especially when turning the wheels while stationary, and the steering wheel may turn more heavily and unevenly. A squeaking steering column (answer A) points rather to worn bearings or a lack of grease. The front of the vehicle swerving to the side when braking (answer B) shows uneven brake operation or damaged suspension. You check the fluid level on the power steering reservoir, and if fluid is going down, you look for a leak, because without fluid the power steering will stop working.
