07_edge_sel

I have a question. I bought my '07 Edge AWD in Feb. and it has approx. 57,000 miles on it. The car has had a loud roar ever since I've owned it. At first I thought it was the tires but after reading this post along with others about the rear wheel bearings/hub assy's, I think I have a larger issue. I too have the "scalloped" or "cupped" tire wear on the inside of the rear tires. My question is, would bad shocks/struts cause the loud roar? Or, do you guys think I have bad shocks/struts along with a bad wheel bearing? I took off the rear wheels/tires last night to see if there was any play in the wheel bearings, but I couldn't move the rotors in any way. The tires will need to be replaced no matter what, but I don't think replacing them will address the roar and wierd tire wear issue. Thanks for the help.

I've been reading the forums about the wheel bearing roar. I was looking to replace my tires, but after doing some research, found that the wheel bearing/hub failures where an issue. I have 57,000 miles on the Edge, and was told by the dealer that the powertrain warranty does not cover the wheel bearings/hub assy's. Does anyone have the part number for the rear and front hub assy's? Is this a dealer only part? Thanks.
