Power Steering Rack and Pump Kit
The Power Steering Rack and Pump Kit includes the power steering rack, pump and its associated components. The power steering rack encloses a piston, and fluid ports mounted on either side of it. Its function is to turn the vehicle's wheels in the appropriate direction. When the steering wheel is turned, a torsion bar that is linked to it gets twisted. This makes the spool-valve assembly regulate the flow of the steering fluid to one of the ports in the steering rack while the fluid on the other side of the piston drains to the reservoir. This action pushes the rack to one side, thereby turning the car's wheels.
The power steering pump is a rotary-vane pump that compresses and sends the steering fluid to the steering gearbox. It is driven by the engine's crankshaft by a belt and pulley. When the engine is running, the steering belt turns, making the pulley and the rotor inside the pump function. As the rotor spins, the fluid is compressed and pumped into the steering gearbox. This compressed fluid causes the steering gear to turn, making the wheels turn in the required direction. To regulate the amount of fluid pumped, a pressure-relief valve is included in the pump mechanism.
The power steering fluid level is vital for the proper working of the power steering rack and pump. A loose rack will make a thudding or a clunking noise. Common symptoms of a damaged rack include a wandering of the car even while driving at low speeds and a shaky or wobbly steering wheel. A leaky pump will not compress the fluid at the required pressure, resulting in a hard steering. A broken vane will cause a rattling or clicking noise. A faulty steering rack and pump should be replaced at the earliest to avoid possible damage to your vehicle's power steering mechanism.
