2005 Ford Freestar intermitten whining noise above 15 mph

Only thing that I can think of is the backing plate/dust shiel behind the rotor may be too close to the rotor, when it's cool check for this condition, and pull it away from the rotor.

We have taken the entire wheel assembly apart, down to the axle, cleaned thoroughly and still making the noise. Could the issue be related to something else, ie vaccum leak, transmission, radiator fans?

thanks.

With a transverse mounted engine, check the serp belt and tensioner pulley, I will look for tech bullitens.
