When the driver provides input by rotating the steering wheel, the hydraulic pump driven by the engine starts pumping the highly compressed hydraulic fluid through lines. The hydraulic pressure produced by the pump enters the hydraulic cylinder which in turn applies pressure over the cylinder’s piston. The piston which is under high pressure starts moving from one end to the another which in turn pushes the further fluid through lines, with this movement of piston the input force applied by the driver is multiplied several times. This high pressure fluid sent by the hydraulic cylinder then applies the pressure to the attached pinion through the coupling mechanism which in turn applies high force to the rack gear and the steering action in the front wheels takes place. Tips: Always wear safety glasses when doing automotive maintenance. As with any job to do it right you’ll need the right tools. Be cautious when working under the hood. If the engine has been running, components will be extremely hot, so be careful what you touch. When working around a running engine, it is important to be alert, and never wear loose clothing or a necktie that can get tangled in belts police or the fan. Be cautious when working with oils and chemicals. Many are damaging to the ground water environment and toxic to people and animals, never drain or pour chemicals into the ground or sewer systems.
