Wheel bearings are a set of steering balls enclosed by a metal ring named 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, which is a hollow chunk of metal at the center of the wheel. The hub holds the lug bolts that you use to bolt the tire onto the wheel. The wheel Bearing is pressed into the hub from the back.

When bearings are damaged and making noise, it's hard to diagnose because you have to drive the vehicle in order to reproduce the sound. The good news is that you can easily improve your ride by replacing wheel bearings. Select from the products or categories below to narrow the selection in Wheel Bearings. Or give us the OEM, model, and year of your vehicle for a more customized list.
