A couple thoughts:
Is the fluid low, is the fluid dirty? Fords can have a whiny sound to them that is not abnormal to develop. The reservior surrounds the pump, so if the pump leaks, it leaks back into the system.
Low fluid will cause cavitation and cause damage.
I have had some luck with additive made by lucas products that has helped. You may want to put an inline filer into the system (and change the fluid if the fluid is dirty) as well, they are cheap.
