In theory, wheel bearings could last as long as your Freightliner. Unlike oil changes or tire rotations, there’s no standard maintenance schedule for replacing them. However, wheel bearings can be damaged if you hit a pothole, smack into a curb or bounce over a speed bump too fast.

If water, grit, salt or sand get to the bearings, the grease in the hub assembly gets contaminated. This will wear down the bearings, and they will eventually give out.

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

If you hear noises at the wheels, one explanation might be a need for a wheel bearing replacement at one or more wheels. The noises might be described as rattling, clicking, humming, growling, or squealing. It can be a real symphony of sound if you’re not careful.

More than just noisy or bothersome, bad wheel bearings could also lead to real performance issues like inconsistent braking, spongy steering and handling, uneven tire wear and, in extreme cases, the wheels could fall off. No matter how much (or how little) you know about cars, you don’t want the wheels falling off, right?

Don’t ignore the issue. Best to get it checked out by a trained service center.

The short answer is: Not for too long. Having bad wheel bearings can range from inconvenient 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 drive.
