The bearing is non serviceable, just replace it. You will need to identify which bearing is bad. To determine which bearing is bad drive the car on a traffic free roadway and steer the car to the left and than to the right. Whichever direction reduces the noise the bearing on the side of the turn is defective. In other words: if you steer to the right and the noise is reduced the right front bearing is defective.
