2008 Dodge Avenger wheel bearing

On more current cars the bearing are sealed and incorporated into a hub assembly. Signs they are going bad include: a hum or roar that can be stopped when turning the steering wheel in one direction but not the other, that is unless both sides have bad bearings. The noise sound similar to a choppy worn tire. Some wheel bearings assemblies have ABS (Anti Lock Brake) sensors built into them, an ABS light may illuminate if one goes bad. Just as a warning, brake rotors that do not have a heat isolating groove in them may transfer heat to the hub and cause wheel bearing failure. Most likely your diagnosis was correct, however what concerns me is that your vehicle is only 2 years old and wheel bearings should last much longer than that. Be certain to keep the proper air pressure in your tires as this can cause premature failure of suspension components.
