Vehicular noise and road noise are a common part of driving. Starting your vehicle brings with it a plethora of noises that you may or may not be familiar with, and so does driving. So let’s say that when you’re driving you start to hear a heavy grinding but only while in motion. That could be the sound of a wheel bearing telling you it’s time to be repaired, or replaced.

When wheel bearings start to go bad it’s imperative to get them checked out and repaired or replaced quickly. Let’s check out a few ways to know if your wheel bearings need some attention.

The other kind of feeling you’ll get from a bad wheel bearing is pulling. The vehicle may be traveling in a straight line, but through the steering wheel you’ll feel it trying to drift to one side or the other.

Well, as a general rule of thumb, yes. When you’ve identified that one wheel bearing has gone bad, then it’s likely the problem has affected the other side of the vehicle. When a part goes bad on one side of the vehicle, the other side of the vehicle tends to compensate, affecting its overall performance, as well.

Unless you’re a mechanic or super-dedicated car enthusiast, you might not know much about the brakes on your car. How long do they typically last?​ How often should you replace your brakes​? We’ve got answers

Let’s check out how a wheel bearing works and why it’s important, and then move on to what it could cost you to get that bad bearing fixed.

Now, you may never have to replace a wheel bearing, as they’re typically pretty hardy. However, if you do, there’s a chance that the wheel bearing opposite the bad one has suffered through the same experiences that the bad one has. Keeping that in mind, it’s safe to say that it’s nearing the end of its life, as well.

The materials used in ball bearings depend on their application. The vast majority of ball bearings are made from steel. Other material types include stainless steel bearings for improved corrosion resistance and hybrid ball bearings for which ceramic balls are the moving parts of the bearing between the inner and outer races to reach high rotational speeds.

Ball bearings use balls to separate two “races,” or bearing rings, to reduce surface contact and friction across moving planes. The rotation of the balls causes a reduced coefficient of friction when compared with flat surfaces rubbing against each other. Because there is little surface contact between the balls and races, ball bearings typically have a lower load capacity for their size than other rolling-element bearings.

RepairPal estimates that in terms of labor you’ll be paying anywhere from $157 to $198 in labor, while the average price for the parts themselves are $169. That being said, being able to do the wheel bearing replacement yourself is a nice little penny saver, if you’ve got the right tools. It’s also important to keep in mind that Repair Pal’s estimate is quoting the costs for doing both the left and the right side of whatever axle the bad wheel bearing is on.

A: A wheel bearing is a crucial component that allows the wheel to rotate smoothly. It can be a ball bearing, roller bearing, or hub bearing, and it’s typically housed within the wheel hub assembly.

Think about it like a skateboard bearing, if you’re familiar, but on a much larger and more complex scale. The wheel bearing is at the center of the wheel hub, and it allows for the wheel to move smoothly. Without it, your wheels wouldn’t spin efficiently, or spin at all, really.

Driving feel can mean a number of things, but in terms of a bad wheel bearing, it will lend itself to a few specifically. The first of these feelings that you’ll find is vibration. When a wheel bearing begins to go bad you’ll feel it in one or two places, either vibrating through the steering column and into your hands, and/or in the entire vehicle itself. This vibration is a pretty good indicator that a wheel bearing may be starting to go bad.

So, if you’ve made it to this point, you’re probably wondering how much it costs to fix that bad wheel bearing of yours. As with all car repairs, the cost can vary greatly by make and model, but according to Repair Pal, the cost of getting your wheel bearing repaired is typically between $326 and $367.

Rolling-element bearings are used to ensure smooth, efficient operation in many machines with rotary motion—from car wheels, engines and turbines to medical equipment. A ball bearing is a type of rolling-element bearing that serves three main functions while it facilitates motion: it carries loads, reduces friction and positions moving machine parts.

GGB's Fiber Reinforced Composite products typically consists of a filament-wound, fiberglass-impregnated, epoxy backing with a variety of low-friction wear-resistant bearing linings. These self-lubricating fiber reinforced composite bearings are particularly effective in applications where the relative motion is not sufficient to promote circulation of the oil or grease used with more conventional bearings. GGB Fiber Reinforced Composite bearings are available as bushes, plates, bearing segments and special forms, depending on the particular material type.

GGB’s TriboU is intended to provide the ​working engineer, who may or may not be a ​user of GGB’s surface engineered solutions, to ​understand and implement basic tribological ​concepts in the design, manufacture and ​use of industrial equipment.

Ball bearing sizes vary according to their use. The width of the bearing also depends on the application. For example, thin section bearings are used in situations where space is at a premium. The difference between the diameter of the outside and inside races and width is minimized, allowing for compact designs.

GGB seeks out collaborative, long-term relationships with each one of our customers. Our diverse expertise gives us a deep understanding of the challenges you face.  When you partner with us early, our GGB engineering team is able to review your assemblies and make sure both the bearing and surrounding components are optimized for performance and cost-effectiveness.

Wheel bearings are the component that allow the other parts of your wheels to work smoothly. The wheel bearings are a series of steel balls encased in the hub assembly of your wheel. They are packed with grease, and as your wheel spins they move inside a race, the metal ring that holds them in place. It’s a closed system, keeping the lubricant inside and the elements out.

Bimetal and metal bearings offer excellent corrosion resistance in industrial outdoor applications and in water, marine and offshore environments. GGB offers a broad range of sizes, forms and materials in monometallic and bimetallic bearings.

When it comes to bad wheel bearings, they’re easiest to identify by listening to your vehicle, as well as paying attention to how it’s handling. With these two simple things, paired with the knowledge provided here, you’ll be ready to diagnose a bad wheel bearing and pay the right price to get it taken care of.

The CoPilot app is the smartest way to buy a car. Built using the same technology that dealerships use, we’ll show you everything you want to know about each listing - like how long it’s been on the lot, or if there are similar vehicles at a better price nearby.

Tribology is the science of wear, friction and lubrication, and encompasses how interacting surfaces and other tribo-elements behave in relative motion in natural and artificial systems. This includes bearing design and lubrication.

Additionally, should the bearing be damaged and the internals exposed, debris from the road can make its way inside. This will also cause that grinding and grating that you’ll be able to hear.

The excellent low friction and high wear resistance performance of GGB metal-polymer bearings make them ideal for hundreds of applications in numerous and diverse industries. Depending upon application requirements, metal-polymer composite bearings can be produced in many shapes and sizes.

There are a variety of different designs and applications for ball bearings, and their design is specific to their industrial application and load type. Some common designs of ball bearings include:

There are a handful of ways to identify a bad wheel bearing, having mainly to do with sound and feeling. Understanding what your vehicle sounds like and feels like under normal conditions is immensely helpful here, as a bad wheel bearing will cause your vehicle to act very differently from what you’re used to.

In most cases, a bad wheel bearing will “tell” you that it’s going bad. They tend to grind, making a loud groaning sound. This is a result of the steel balls making contact with the race due to a lack of lubrication. Unlike engine components that require lubrication, wheel bearings are packed with a grease that is not replenished automatically. In other words, it’s got all the grease it’ll have until someone gives it more.

GGB's Engineered Plastic Polymer bearings provide excellent wear resistance and low friction in both dry and lubricated operating conditions over a wide range of applications. Engineered plastic bearings are made from thermoplastic bearing material processed by injection moulding. This production method enables us to produce unlimited dimensions in accordance to our standard, and also parts with special designs and features.

Another sign that your wheel bearing is going bad is wear on your tires. Often, tires can wear unevenly due to alignment issues, but in the case of a bad wheel bearing you’ll most often find that the wear on one tire is worse than the others. This is the bad wheel in the bunch. This uneven wear is noticeable, and will persist on the wheel with the bad bearing as you rotate your tires.

Now, you may be thinking this is an alignment issue, and it could be. One way to tell the difference between the two is the consistency. When a wheel bearing causes pulling, it may only cause it to happen randomly, then things will sort themselves out again. An alignment pull will be continuous.

A: Common signs include grinding or roaring noises from the wheel area, a feeling of looseness in steering, or uneven tire wear. If the issue lies with the steering knuckle or hub assembly, you might also notice steering problems.

A: Often, yes. The wheel hub assembly includes the hub bearing and other components. Replacing the entire assembly can be costlier than just the bearing, but it might be a more comprehensive solution, especially if other parts are worn out.
