Low Speed Squeal

[LAndrews5045]

I have a 07 Yukon with 106,000 miles and it is making a intermittent squealing sound from what sounds like the right rear. It only happens at speeds about 5 MPH then goes away when acceleratiing. I posted a video on youtube: https://www.youtube.com/watch?v=1pcUhU8LhF4

Please Help.
