The importance of wheel bearing

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. If you notice a humming or whirring noise while you are driving or your ABS light turns on, it may be time to change your bearings. You can save money by changing your own wheel bearings rather than going to a mechanic, but if you do so, use caution – the bearings may be small, but they’re very important.
