Rack-and-pinion is the most common steering system in late-model cars. It can be part of a hydraulic or electric power steering system. The steering rack, which is controlled by the steering wheel, directs the rod-operated linkage, which causes the wheels to turn. In a hydraulic power steering system, a pump provides the required pressure. The pipes and couplings should be inspected regularly to ensure they aren’t leaking hydraulic fluid. Your certified NAPA AUTOPRO technician can inspect these parts during routine maintenance and, if necessary, change the fluid to eliminate contaminants, according to the manufacturer’s recommendations. Hybrid and electric vehicles use electric power steering systems. This type of power steering is gaining ground because of reduced fuel consumption. The vehicle’s central computer controls the power steering according to specific parameters, such as vehicle speed and steering wheel angle. No matter the type of steering system in your vehicle, the steering rack, tie rods, ball joints, and core housings should be inspected on a regular basis. Your certified NAPA AUTOPRO technician is the perfect person to check all the components in your steering system.
