Steering Wheel Humming on 2005 Ford Escape

Why does my steering wheel make a humming noise? It's much worse in the morning. There is no vibration or shaking only a humming noise and it usually goes away after being on the road for a while.

First thing is to make sure the power steering reservoir is at the full mark and if it is the power steering pump is probably beginning to fail, have a tech check this for you
