There are various different kinds of braces out there and most cars will be slightly different, but they all perform the same task. A wheel bearing works to help the wheel spin with very little friction. A wheel bearing replacement costs between $112 & $696 for most cars. On your car, the bearing supports the wheel and rides on the axle shaft. It fits into the hollow section at the center of the wheel, and is held in place by the lug bolts which attach the wheel to the car. The wheel bearing is pressed into the back of the wheel, before being bolted into place.
