Wheel bearings are metal balls held by a ring and allow the wheel on your vehicle to spin with as little friction as possible. Over time, bearings can break down due to a lack of lubrication and typical wear and tear. Driving on a bad wheel bearing can be dangerous, and could cause severe damage to your vehicle if you continue to drive on it. Luckily, diagnosing a failing wheel bearing is relatively easy and you can usually determine if there's a problem by listening to your wheels and evaluating any changes in your car's handling.
