An apparatus (30) which controls the motion of a cab (12) of a vehicle relative to a frame of the vehicle includes a cab motion control motor (38). A pair of motor control valves (70 and 72) are provided to control fluid pressure conducted to the cab motion control motor (38). The motor control valves (70 and 72) are supplied with fluid under pressure by a power steering pump (22). The power steering pump (22) also provides fluid under pressure to a power steering motor (20) which is operable to turn steerable vehicle wheels (18).
