An apparatus (10) for use in turning steerable vehicle wheels (12) includes a steering wheel (18) and a power steering motor (20) which is operated in response to rotation of the steering wheel. A first spring (120) is connected with the steering wheel (18) and urges the steering wheel to rotate in one direction. A second spring (124) is connected with the power steering motor (20) and urges the power steering motor to operate in a direction to urge the steering wheel (18) to turn in a direction opposite to the direction in which the first spring (120) urges the steering wheel to turn. The two springs (120, 124) cooperate to take up lash in a linkage (24) between the power steering motor (20) and the steering wheel (18).
