Wheel Bearing Replacement FAQ

FAQ

• What are wheel bearings?

  Wheel bearings are a vital part of a vehicle’s braking, steering and suspension systems.  They’re a set of steel balls or tapered bearings that sit inside the one-piece hub assembly, located between the drive axle and the brake disc or drums. Bearings allow the wheels to turn smoothly, with as little friction as possible.

  The bearings themselves are packed tightly, encase in grease and sealed into a waterproof ring. This housing, called a race, is located inside the hub and each wheel has one.

• What does it cost to replace wheel bearings?

  The cost to replace one front-wheel hub assembly varies widely. Some variables include the make and model, the garage’s labor rate and the cost for parts.

  The national average is about $350 to fix the wheel bearings at one wheel. As you might imagine, however, luxury brands cost more.

  Please note: If the wheel bearings need replacing at one wheel, you don’t necessary need to replace the bearings at the other wheel on the same axle. It’s not like matching a pair of tires.

• How long do wheel bearings last?

  In theory, wheel bearings could last as long as your car. Unlike oil changes or tire rotations, there’s no standard maintenance schedule for replacing them. However, they can be damaged, especially if you hit a pothole, clip a curb or drive over a speed bump too fast. (And who hasn’t done that?)

  If water, mud, road salt or sand get to the bearings, it will contaminate the grease in the hub assembly. In turn, the bearings will wear down, and eventually fail. In addition, ignoring worn-out wheel bearings can damage the vehicle’s inner or outer CV joints (constant velocity joints), which attaches to the driveshaft and transmission.

  The best course of action? Find a reputable service technician for advice.

• What happens when the wheel bearings fail?

  Having bad wheel bearings can range from inconvenience and unpleasant to downright dangerous.

  If you have bad wheel bearings, you might experience the vehicle pulling to one side, sloppy or loose steering, grinding and rattling noises, and uneven tire wear.

  In the worst case scenario, the wheel could come off while you’re drive. And even if you don’t know a lot about cars, you probably know that would be BAD.
