Chevrolet and GMC Heavy-Duty Trucks Move to Electric Rack Steering

Chevrolet and GMC are retiring the ball-nut steering box and its fluid-driven power assist on their heavy-duty pickups, and moving to a steering rack with electric power assistance. The fluid pump and ball-nut gearbox have been part of these big trucks for a long time. The rack with an electric motor is the arrangement most drivers already know from ordinary passenger cars. For owners who tow a horse trailer on a Colorado mountain pass or haul a boat to a Florida launch ramp, this is a real change in how their working trucks are engineered.
