Product Description
The CARDONE 21-5310 Remanufactured Power Steering Pump is engineered to provide OE-level steering performance while enhancing long-term reliability. Each unit begins with a detailed evaluation of the original design, allowing CARDONE engineers to identify and upgrade internal components where necessary.
Every pump incorporates triple-tested internal mechanisms, premium HNBR O-rings and seals, and precision-machined shafts to ensure exceptional durability and leak resistance. Relief valves are individually calibrated for correct hydraulic pressure, ensuring optimal steering response under all conditions.
Each assembly undergoes complete computer-controlled hydraulic testing, validating pressure output, flow rate, noise levels, and overall performance. The eco-minded remanufacturing process reduces energy and raw material consumption by up to 80%, delivering a cost-effective and environmentally responsible alternative to new OE pumps.
