The power steering mechanism used in the modern cars has pinion gears. The inner valve moves the rack which rotates the pinion gear according to the direction that you turn your steering wheel. The power steering rack differs slightly from the manual rack and pinion. The difference is in the design of the rack. In power steering, the rack has a cylinder with an inner valve in the middle. There are two fluid ports on the either side of the inner valve that carry steering fluid from the steering pump. The inner valve moves with the force from the high pressure fluid which creates the power assist that helps move the steering rack.

If your steering system is acting strangely, you need to have it checked as soon as possible. If you find that the BMW power steering rack is malfunctioning, you need to replace it immediately.
