An apparatus for use in turning steerable vehicle wheels includes a rotatable output shaft. A first rotational input assembly is provided for transmitting a steering command from a steering control member to the output shaft. A power transmitting mechanism is configured to transmit the rotational force from the input assembly to the output shaft. The power transmitting mechanism includes a plurality of sector gears. A ball screw has longitudinally separated first and second ball screw ends. A ball nut has a plurality of rack gears. Rotational force from the input assembly turns the ball screw, and the ball nut reciprocates within the housing responsive to rotation of the ball screw to move each of the plurality of rack gears in a longitudinal direction. Longitudinal motion of the rack gear teeth responsively drives the sector gear teeth to transmit the steering command to the output shaft.
