Tipu

Hi, I got 2012 Edge with US specifications. Recently got water-pump and condensor repalced...also the AWD propellor was removed as it had some damage. However, there is continuous squeaking noise from rear wheels when in motion, and once brakes are applied the noise stops (if the brakes are applied lightly, the noise kind of becomes worse). What could be the issue? One local mechanic suggested to me that wheel bearings need to be changed.
