Steering returnabilty or "return to center" is impeded by electric power steering assist. According to Ford the new electric over hydraulic system installed on some Super Duty trucks assists the driver during cross wind or heavy road crown situations. But when there is no wind or road crown the system continues to "assist" and holds the steering column from immediately returning to center. This vehicle is not equipped with a "lane keeping' or "auto steer" system. Under certain conditions the vehicle requires constant left and right input to maintain lane.when driving between 30 mph and 50 mph the vehicle will continue to navigate turns after the steering wheel is released. This constant input is very fatiguing and when road conditions are slippery, icy or rough maintaining lane is extremely difficult at times.
