The hub bearing assembly is part of the mechanism of a car wheel. It is the assembly of hubs and bearings that facilitate the rotation of the wheel on the road surface.
The hub bearing assembly consists of a wheel hub on which the bearings are mounted. The hub is attached to the axle and the bearings keep the wheel spinning smoothly. Hub bearing assemblies differ between front and back wheel sets.
A new wheel hub assembly should last up to 150,000 miles, after which it will probably need to be serviced and, eventually, replaced. If possible, replacement parts for specific makes and years should be found.
Signs that wheel bearings are faulty include wobbling of wheels, or a low growl or hum indicating too much friction. On detecting these warning signs, it is critical that you take your car to a mechanic to avoid further damage.
