What are Front Wheel Bearings and Hubs and where are they Located?

Your front wheel bearings and hubs are important parts of your vehicle's steering, suspension, and braking systems. Most modern vehicles use a one-piece hub assembly that incorporates the hub, wheel bearing, ABS wheel speed sensor, and mounting flange. While less common, there are still some vehicles that still use a separate wheel hub and press-on bearing. Front wheel hub and bearings typically mount on the end of the front spindle (knuckle), between the spindle and your front brake rotor. The hub itself is what holds the brake rotor and wheel onto the vehicle.

How do I Know if my Front Wheel Bearing and/or Hub Needs to be Replaced?

A wheel hub itself rarely has problems because it is simply a block of steel. The most common reason why a front wheel hub needs to be replaced is because the wheel bearing that is attached to it has failed. Wheel bearings can fail because of age, dirt and water contamination, or improper installation in the case of a two-piece hub and bearing assembly. A worn out front wheel bearing will usually make a grinding sound which is more noticeable when turning in the direction of the side with the worn hub. Another reason why a wheel bearing and hub assembly will need to be replaced is if an ABS sensor has been built into the hub itself and it is not working. When this happens, even if you have a perfectly good working hub, the entire front wheel hub and bearing assembly has to be replaced.

Can I Replace a Front Wheel Bearing / Wheel Hub Myself?

Wheel hubs and wheel bearings are usually a job that requires some automotive experience. If you live in a dry, low-rust area, then they are far easier to replace. In the areas where vehicles rust, front hubs - and hubs in general - can sometimes be a bear to remove. Use plenty of rust penetrating oil, and gather up as much patience as possible before beginning the job. If you have never replaced a wheel bearing and hub assembly before, a service manual is invaluable for a job like this. For vehicles that use a press-on bearing, professional installation is recommended.

Need a Replacement Front Wheel Bearing, Hub or Hub and Bearing Assembly?

Properly functioning front wheel bearings and hubs are essential to the operation of any vehicle. Therefore, regardless of if you have a one or two-piece hub and bearing assembly, if any component has failed a replacement of some kind will be required. If you are in need of a replacement part, then you have come to the right place.
