Check the Nose Wheel Steering Actuator rod ends for play. The bearing is press fit into the rod end, if you pull the bolts out, and the bearing falls out of the rod end, the actuator is bad. Both actuators usually go bad at the same time. There are 2 modes for the steering control valve, shimmy dampening and steering. In shimmy dampening mode a small amount of fluid is ported to both actuators for a shock absorbing effect. if the tires, bearings, Control Arm Bushings and cable tension is good... only then change the steering control valve.
