Product Description
The CARDONE 21-5446 Remanufactured Power Steering Pump is engineered to restore factory steering performance with enhanced durability and reliability. CARDONE’s remanufacturing process improves on OE shortcomings by using upgraded materials, precision machining, and rigorous testing.
Every pump is equipped with 100% new O-rings and high-grade HNBR seals, which resist heat and fluid breakdown better than standard materials. Critical internal components—including campacs and spool valves—are triple-tested to ensure smooth, consistent steering assist.
Each unit undergoes a complete hydraulic efficiency test, analyzing flow, pressure output, noise level, and bypass operation. Precision-ground shafts reduce friction and prevent premature seal wear, extending pump life. As a remanufactured OE unit, the pump is guaranteed to fit and perform as intended.
CARDONE’s eco-conscious process reuses up to 80% of the original pump body, significantly reducing waste and energy consumption.
