Steering EH (Electro-Hydraulic) valve is failing, time to replace it. Before you do that pay attention to how it drives when transporting, if you are constantly correcting the steering wheel to maintain a straight line then you need to replace the complete valve, The spec is 2/5th's of a turn of the steering wheel per mile. if not then replace the EH portion of the steering valve.
