Been hot here in missouri, sound came out of nowhere, no lights on drives wonderful just making this loud hollow sound from under the hood, starts loud then gets low but wont go away, some says that maybe the plastic cover on the fan may have come lose, all the belts are fine so we re thinking something has gotten in and jus rubbing against something, HELP
Check plastic on front of car wheel wells give same sound missing plastic screws
SOURCE: What is this loud rubbing sound I am hearing when I am driving?
Your pads NORMALLY will ride on the disks, they will NOT normally make any rubbing sound.
I doubt your calipers are stuck unless you drove into the seawater at Daytona or something similiar. To test, chock rear wheels, jack up front of car, spin L and then R wheels by hand, if they spin whthout much effort, your front caliper pistons are probably fine. Flip car around and repeat for other end;~)
You may find one of the rear wheels has a grinding feeling and some play if you grab it top and bottom and try to wiggle perpendicular to the line of travel. If this is the case you need a wheel bearing, could be on the front bearing, but my jetta experience says rear bearing (twice).
DO NOT BUY CALIPERS unless you know they are bad, they shouldn't be bad and they are expensive.
Good luck and post us back

I had the same problem at about the same mileage. Replaced the power steering pump and the start up screaming went away! ( The Jeep's and mine!)

You can check fluid level by removing the rubber plug in the cover. Fluid is full when on level ground, it is just at the edge of the hole (or very close) if you are already getting noises out of there, you can remove the cover and inspect gears for wear or breakage. If you find a large amount of metal debris in the lube it tells you something bad is going on back there. Although rebuildable, it's not a home job...requires exact settings in order to operate properly. You can find good units far cheaper than even a gearset costs in any scrapyard. to match ratio, count the teeth on the ring gear and the pinion gear. the replacement MUST have the exact same number. Before swapping diffs, check all back there to make sure noise is not from somewhere else.
