Wheel Bearing Replacement near Oak Park, Illinois

Some vehicles with sealed front wheel bearings can be serviced at home. If the wheel hub and bearing are simply bolted to the knuckle and can be replaced as a unit, an intermediate DIYer with experience removing brake or suspension parts can do it. But many cars require that a technician remove hubs and bearings that are pressed into the knuckle. These components are difficult to disassemble, and reassembly requires a hydraulic press. In such cases, wheel bearing replacement is best left to a professional technician.

To diagnose whether a wheel bearing is going bad, a technician will typically take the vehicle for a test drive to verify where the sound is coming from and determine which wheel bearing is the culprit. In the shop, the technician might lift the vehicle, rotate the wheel, and listen for sounds from the wheel hub. The technician will also test the wheel for excessive play by holding the tire on each side and rocking it back and forth. If there is play in the wheel and the steering and other suspension components are in good condition, the bearing has likely worn out.

The front wheel bearing is an essential component of the vehicle suspension. As a wheel bearing wears out, more friction is created — and more damage occurs. On most vehicles, the wheel bearing requires special equipment to be serviced. If a bearing is installed improperly, it may fail early.
