If louder when turning right, bearing prob gone on left, as more weight will be on that side, obv causing more noise. Jack up car, and shake wheels from side to side to check for excessive play. You could check other good one for play as a comparison if unsure. To find out front or back bearing, get someone to sit in car with head out of near side window and hear where noise is comin from. Hope that helps, ed. :)
