I'm not following how the steering rack could be generating this problem, without it being obvious as you steer. Driving straight ahead, there shouldn't be anything moving within the rack generating noise. Servo motor is stationary.
If it is the rack, I'd expect it to change sound as you move the steering wheel a few degrees each way, at various driving speeds, and require changeable torque, to assist the movement.
