Product Description
The CARDONE 21-5391 Remanufactured Power Steering Pump is designed to meet or exceed OE performance standards, delivering reliable steering assist and long-lasting durability. Every original pump design undergoes a full analysis to identify opportunities for improvement, and upgraded components are integrated where applicable to enhance longevity.
Each unit features triple-tested internals, including campacs and spool valves, ensuring consistent hydraulic operation. The pump is built using 100% new O-rings and premium-grade HNBR seals, which resist high-temperature degradation far better than conventional materials—preventing leaks and extending service life. Shafts are precision-finished to reduce seal wear, and every pressure relief valve is individually calibrated.
Before shipment, every pump is computer-tested to verify performance across pressure, bypass function, flow rate, valve operation, noise level, and steering effort. As a remanufactured OE component, it guarantees a perfect fit. CARDONE’s process also reduces raw material usage by up to 80%, making this an environmentally responsible choice.
