Product Description
The CARDONE 20-7940 remanufactured power steering pump restores factory-smooth steering response for Chevrolet and GMC R/V-Series Suburbans and full-size SUVs (1989-1991). Each pump is precision-engineered and tested to exceed OE performance standards. CARDONE’s process includes triple-testing of all critical components—cam packs, spool valves, and pressure relief valves—and computer-controlled hydraulic testing for pressure, bypass, and flow integrity.
All units use 100 % new premium-grade HNBR seals and O-rings, formulated to resist heat and fluid breakdown, ensuring leak-free, long-lasting performance. CARDONE’s eco-responsible remanufacturing approach saves up to 80 % in raw materials and energy compared with new part production.
