You may also start to feel it through your steering wheel or in your backside seismograph. Again, a wheel bearing’s job is to ensure your wheel spins smoothly. When it doesn’t, you’ll probably start sensing unpleasant vibration and noise throughout the passenger cabin.

Since a wheel bearing is located at or near the wheel, the noise will probably be coming from one corner of your vehicle—provided you’ve only got one bad bearing, of course.

The key word above is “listen.” Though you may be able to jack-up your vehicle and check the wheel for movement and play, noise will typically be your first (and best) indicator that you’ve got a wheel bearing on its way out.

Wheel hub bearings help reduce the amount of friction between cars and their wheels, reducing noise and improving drivability and fuel economy. Be sure to take care when doing maintenance on this part, as proper installation is key to a car running as smoothly and safely as it can.

For a car to drive, its wheels need to turn quickly. Want an idea of how quickly? A typical wheel on a car driving about 100 km/h is spinning a little faster than 840 times per minute. Wheel hub bearings help reduce the amount of friction that this many revolutions will cause, helping to reduce the amount of heat and wear the car will experience.

I’m confused at the question – but if you’re asking about handling then yes, a bad wheel bearing can affect the way the car handles and moves—it’s not something you want to drive on, so if you suspect it’s going bad, have it inspected as soon as you can.

Very, very good point–we’ve even seen folks pinpoint a trailer bearing that was physically hot to the touch. Heat’s a key byproduct of friction, so it’s often a telltale sign of a bad bearing.

It’s important to note that not all wheel hub bearings are equal, and exceptionally cheap ones are likely not worth purchasing. They can degrade more quickly, tend to be less resistant to the elements, and can even produce the kinds of annoying sounds that a functioning wheel hub bearing shouldn’t. If, in your career, you want to ensure your clients get the best service, it’s a good idea to recommend that they don’t go too cheap on wheel hub bearings.

Hey Randy, it’s no so much a turn as it is a gentle, momentary veer–enough to unload weight on the opposite side for a fraction of a second. Once the steering wheel returns to neutral, the weight re-centers and the noise returns. Make sense?

When wheel hub bearings wear down, it’s typical for a car to start making a variety of noises, including grinding, snapping, clunking, and other unsavoury sounds. Most cars can get by for a good while if the wheel bearing is degraded. If the wheel hub breaks completely, though, it can hamper a wheel’s ability to spin so much that the car could conceivably stop moving altogether. As a result, graduates of auto technician courses make sure to explain to their customers that even if their car is drivable, it’s unwise to let worn wheel hub bearings go unfixed for too long.

It’s always a challenge to describe a noise in text, but a bad wheel bearing will often start out as a “growl,” sort of like a dull, soft grinding noise. It can also be a whine, a hum, or a soft roar. In some cases, bad wheel bearing noise could even manifest as a clunk or squeak.

Hello Marius, it’s not a turn, per se. It’s a slight, gentle shift (left or right) while you’re moving in a straight line—just enough to take some weight from the other side of the vehicle for a slight moment. When it’s unloaded, the noise may stop and, when it shifts back, it may start back up. … Again, it’s not a 100% scientific diagnostic, but it’s worked for us several times in the past.

That’s because veering like this shifts the weight off the side of the particular offending wheel for a few moments. Now unloaded with less stress, the bearing might shut up for a second and be perfectly content. When the vehicle weight shift returns to normal, the bearing is back to being loaded and it’ll start to whine again (sometimes literally).

The noise/vibration might only be noticeable at certain speeds, and it may even go away momentarily depending on chassis movement (more on that in a sec). In any event, it’ll likely get worse as the bearing continues its progression towards complete failure, so it’s good that you catch it as early as possible.

Among those parts are “wheel hub bearings.” Nestled between the brakes and the axles of a car, they are instrumental in getting cars to drive smoothly. When they fail, performance can be harmed, or the car might even stop moving altogether.

So while at highway speeds, if you can safely(!) rock the steering wheel slightly left and right to shift the vehicle’s weight to each side, it may further help you diagnose where the noise is coming from.

It often boils down to both the vehicle and the driving conditions. All-wheel-drive cars put different demands on wheel bearings than, say, front wheel drive cars. Late-model performance cars place stresses on wheel bearings that regular commuter cars don’t. Mud-slinging off-roaders subject their wheel bearings to muck and grit that a street-driven car rarely sees. Make sense?

Hey Patty, I checked and it looks like, for the GMC Terrain, they’re sold as a wheel bearing & hub assembly, just like the ones in the topmost picture of this article—which typically makes them a bit easier to replace. Currently, Summit Racing carries over a dozen different types, with quite a few in stock, ready to ship. Click here to see the wheel bearing hub assemblies for 2013 GMC Terrain. (Or, there’s a good chance you’ll be able to find a replacement at your friendly local auto parts store too.) … Just remember to order the correct one for the correct wheel–Front or back, driver or Passenger side—as the application can differ a lot, particularly on AWD vs 2WD models. Good luck!

The takeaway here is that early detection is important. And narrowing it down to the precise wheel can help save you some time and money in diagnostic costs.

When working in your auto mechanic apprenticeship and in your career beyond, take care to ensure that you install new wheel hub bearings correctly. Misalignment, or accidentally installing the bearing backwards, can lead to the ABS light staying on constantly in your client’s car.

Few things in automobiles are as simple as they appear. Take, for example, the wheels. At first glance, it might look like they just spin when a driver steps on the gas, and halt when brakes are applied, but there are many smaller steps involved to get from driver input to wheel action, and many hidden parts making the whole process easier.

A wheel bearing is typically composed of a series of small roller bearings arranged in a circle and encased in a durable shell. The assembly is packed in grease and sealed to prevent excessive moisture and grit ingress. Then, the whole thing slips around the vehicle’s axle or spindle, where it can spin right round, baby.

That’s a tough question to answer with a definitive mile threshold. We hear tell of wheel bearings lasting the life of the vehicle, like 200,000 miles and up. Conversely, some cars (cough*old Subarus*cough) seem to go through wheel bearings every few years or so.

Also you can check a bad bearing buy taking off the grease caps then taking on a short run. Stop the car and with a thermometer point it at the centre of the bearing both sides of the car.The hottest bearing is the most worn and will give the loudest noises.

As with so many other automobile components, a functioning wheel hub bearing improves the fuel efficiency of a car. This is directly related to a wheel hub bearing’s ability to reduce friction. In this case, more friction means more “wasted” energy, and worse fuel economy.

How to tellwhich wheelbearing is badin the front

It’s usually pretty easy to determine if the noise is coming from the front or back, given the driver’s seating position and their proximity to the front wheels. The hard part is often determining whether the noise is coming from the left or right (driver or passenger) side of the vehicle.

But given the amount of times it has to keep the wheels spinning really, really fast (and the rain-, dust-, and salt-rich environment it often has to work in), a wheel bearing will eventually wear out. While a failed wheel bearing can be a big problem, the good news is, it’ll probably give you plenty of warning that it’s going bad—you just have to know what to listen for.

How to tellwhich wheelbearing is badwhile driving

A wheel bearing has a real simple job: It makes sure that your wheel spins freely, without any binding or vibration. A wheel bearing’s goal is to mitigate the effects of friction, which ultimately improves your car’s ability to roll smoothly—all while reducing wear to ensure it’s able to do so for a long time.

But before you point the finger at a wheel bearing, you want to make sure the noise isn’t coming from somewhere else. So here are a few things to consider:

Wheel hub bearings often house ABS sensors, giving them added utility and purpose in a vehicle. It’s important to note, though, that this can also make a wheel hub bearing replacement a bit trickier.

But good news there, as there’s an easy test that may help. While it’s not 100% foolproof, if you notice the noise stops while you’re slightly veering left or right, then an opposite side wheel bearing is the likely culprit.

When driving in snowy, icy, or otherwise slick conditions, most cars will engage an “anti-lock braking system” (ABS) if the vehicle detects that it is skidding when the driver is attempting to stop. This can help drivers maintain more control of their vehicles, potentially allowing them to avoid accidents.

Thanks to a penchant for vintage Honda motorcycles, he spends the rest of his time fiddling with carburetors and cleaning chain lube off his left pant leg.

If you turn left, you unload left wheel, sake with right. If you turn left and sound dissapears it means that your left bearing is bad.
