Which component assists the driver in turning the steering wheel?

The power steering pump is designed to assist the driver in turning the steering wheel by providing hydraulic pressure to the steering mechanism. When the driver turns the steering wheel, the power steering pump creates pressure in the power steering fluid, which is routed to the steering gear. This pressure helps reduce the effort required by the driver to turn the wheel, making steering easier, especially at low speeds or during parking maneuvers.

In contrast, the brake system is primarily responsible for slowing or stopping the vehicle, and while the suspension system supports the vehicle’s weight and provides stability during turns, it does not actively assist in turning the steering wheel. The transmission is involved in transferring power from the engine to the wheels and does not play a role in steering control. Therefore, the power steering pump is the critical component that enhances steering ease and responsiveness for the driver.
