Abstract: An apparatus (10) for use in turning steerable vehicle wheels (14, 16) includes a steering member (12) which is linearly movable relative to the vehicle to effect turning movement of the steerab!e vehicle wheels. A pinion (28) is disposed in meshing engagement with a rack portion (30) of the steering member (12). A steering column (22) is connected with the pinion (28) and with a vehicle steering wheel (20) such that rotation of the steering wheel results in linear movement of the steering member. An electrically powered steering unit (40) is connected to the steering member (12) for providing steering fee! to the operator. A hydraulic power steering motor (60) mechanically connected to the steering member provides steering assist to the steerable wheels (14, 16).
