dont buy a new pump, drain power steering fluid yourself with front end jacked up, replace fluid with ford type F tranny fluid, bleed system by turning wheels left to right and noise should stop or almost stop. one thing is, ford uses plastic gears in the pumps, most bulk steering fluids or hydraulic oils will make these pumps have a whine to them. these pumps were designed years ago a ford stuck with the plastic gears, which do fine with the right oil inside them. the run really quiet with old ford type f tranny fluid in them
