Hey all! My 2010 Yukon Denali has a horribly loud, annoying, noise that sounds like brake squeal but I've changed the brakes and see nothing wrong. I've cleaned, inspected and can't find anything. It does it around 60mph cool and lower speed after driving awhile. It comes in and out and stops when braking. If I don't figure this out soon I'm going to start wearing ear muffs while driving. Any advice would be greatly appreciated.
