Product Description
The CARDONE 21-5366 Remanufactured Power Steering Pump is engineered to restore factory steering assist while delivering upgraded durability and reliability. Each unit undergoes a thorough OE-performance review to identify potential improvements, resulting in a pump that often outperforms the original design.
Every pump receives precision-machined shafts, 100% new premium HNBR seals, and triple-tested internal components such as cam packs and spool valves to ensure consistent hydraulic output. Pressure relief valves are individually tested and calibrated, ensuring proper steering feel across all driving conditions.
Before packaging, the complete assembly is computer-tested for pressure, bypass, flow, steering effort, and noise. CARDONE’s remanufacturing process also helps the environment by reducing waste and lowering raw material consumption by up to 80% compared to new production, while still providing an OE-fit solution.
