Could be wheel bearings, but I would expect wheel bearings to consistently make the noise. When mine went out, the noise was there when going straight ahead, or when turning to the left. There was no noise when I turned right. I consistently got the noise on left turns or straight ahead though.
Are your lug nuts torqued correctly? You may want to jack up the front wheels and see if you can identify any looseness in the front end.
