Ruville wheel bearing is a set of steel balls held together by a metal ring called a race. They help wheels spin fast with as little friction as possible. They are used on all kinds of vehicles, from bicycles to aircraft and cars. On a car, a wheel bearing rides on a metal axle shaft and fits tightly inside the hub.When wheel bearings wear out, they can create excessive noise and heat, which leads to poor fuel economy, unstable steering, and potentially even further damage to steering components. Read your car’s owner’s manual to determine replacement intervals for your wheel bearings, or get a professional to perform a check.

The wheel bearing’s two primary functions include ensuring the wheel rolls along the road and supporting the weight of the vehicle. If you’re lucky, wheel bearings can last up to 150,000 miles.Wheel bearings are a vital part of a vehicle's suspension. Usually located in the wheel's hub, rotor, or brake drum, bearings help the wheel rotate smoothly when the vehicle moves.
