So Fix it

There are several ways to identify a faulty wheel hub bearing assembly, most notably if the vehicles ABS warning light comes on. Strange noises, while turning the steering wheel, are another sign of a bad hub bearing assembly. These include growling or humming noises, usually at speeds around 35 MPH.

Many of todays vehicles are equipped with anti-lock brakes. Often times these vehicles will have anti-lock brake sensors built directly into the hub bearing assembly. On vehicles where this is the case, if the sensor goes bad, then replacing the entire hub assembly will be necessary to remedy the problem.

You can save money by replacing a hub bearing assembly yourself if you possess the know-how and the right tools. Some of the tools needed include a floor jack, a flat head screwdriver, sandpaper and a rubber mallet.

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.
