My Girlfriends 2008 Ford Edge AWD squeeks in reverse only. ive replaced the pads and rotors to stop the squeeks, i didnt go cheap on them either, but i cant seem to figure out what is causing it. it has 30K miles on it and the dealership just tells me its normal. Then i found this article today, check it out. i guess its a pretty common issue with other vehicles also. I think this will be my next move to see if it fixes it. Hope this helps everyone also!
