Good to hear people are getting this solved. This just started on my car last week and it's getting louder and more frequent. The sound is the same as the classic bad brake pad squeal. It sounds like it's the right front but it's tough to tell. Happens at low speeds (5 - 15 MPH) on shallow left turns or when going into/coming out of a sharper left turn. It doesn't seem to be there when engine braking, only when accelerating or maintaining speed.

'06 w/ 29,300 and I assume OEM pads FWIW
