CARDONE Remanufactured Power Steering Pumps are engineered to meet or exceed O.E. performance. Original designs are scrutinized for potential improvement, and where applicable, design upgrades are implemented to produce a more durable part than the original. All critical components are tested to ensure proper function. Every unit undergoes a hydraulic efficiency test to ensure reliable, long-lasting performance. Final pump assembly is computer-tested to measure pressure, bypass, fluid flow, valve operation, steering effort and noise to ensure reliable performance.
