Jack the car up on each side and hold wheel at 12 and 6 o'clock position and check for slackness, repeat on 3 and 9 o'clock position, this will give U a good indicator if its the wheel bearing or not, also check to ensure UR CV boots are intact, maybe dry or worn Cv joint, easiest way of checking this is to turn the steering full lock Clockwise and turn the car 360, repeat for CCW, if you hear clicking grinding maybe Cv is shafted?
