To confirm if it's the wheel bearing, try to find a long downhill road, then once you are rolling down turn off the engine and start making long S shaped turns, if your noise gets louder during a long 'left turn', then it's your right side wheel bearing..
But, ideally you should replace both sides as the driver side has just as many miles on it, it's a simple job, however is Not a fun job (it's a bear of a job to remove the old bearing, if you choose to leave the hub in place)
Note: When you install the new bearings note their correct orientation as one of their sides has the magnetic trigger for the ABS sensor, ask me how I found out..
