This sounds like a failing power steering pump assembly.I have seen the pump fail in the past before and start to whine like this with it needing replaced.I would check and make sure there are no leaks as the pump can suck air and fluid if there is a slight leak and cause this as well but if there are no leaks then the pump needs replaced.
