The steering gear box is the heart of the vehicle's steering system. It guides the wheels' movement in conjunction with the direction that the steering wheel is rotated, helping achieve ideal steering response for more efficient driving. CARDONE Remanufactured Steering Gear Boxes are re-engineered, built and tested to match O.E. performance. Each unit features 100% new O-rings and lip seals to ensure leak-free, long-lasting performance. Shafts are surfaced to precise specifications to eliminate premature seal wear and extend gear life. All units are 100% hydraulically tested to ensure perfect fit and function.
