2001 FORD EXPEDITION MAKES NOISE WHEN WE HIT OVER 50MPH on 2001 Ford Expedition

we have 2001 Ford expedition and when we drive on the streets its fine but once we hit the freeway or a highway with a speed of 50 mph and more it will start to make this metal to metal sound coming from i think the rear. we taught it was the bearings but not to sure.. we already got the tire balance done and tires checked but im really concerned if its something servrly wrong with it .. hope i explained my self right thanks for any input out there

I would stick with your diagnosis. It does sound like the wheel bearings are the likely culprit.
