There is a slight difference in the design of the steering rack in a power steering system. Unlike a manual steering rack, the power steering rack has a cylinder with an inner valve at its core. The inner valve is connected to the rack and moves when steering fluid is passed from the steering pump. There are two fluid lines on each side of the inner valve. One line supplies high pressure fluid to the inner valve which makes the steering rack move according to the direction you turn your steering wheel. The fluid supply dictates the movement of the wheels. When all of these components are working together properly it makes turning the steering wheel easier for the driver.
