As discussed earlier, external noise impacts urban life. Noise regulation is different in each country. The European Union (EU) tire labeling regulations for passenger car and light truck tires, for example, went into effect November 1, 2012. This information helps consumers make a conscious decision during the tire purchase (see the European Tire label in Figure 3). The label consists of three criteria: wet braking (A), fuel efficiency (C) and pass-by noise. While a lot of people think the noise level on the label is an indication of indoor noise, it actually indicates noise pollution or external noise measured by a pass-by noise vehicle test. A tire rated one wave is half as noisy as a tire rated with two waves. Pass-by noise is measured from the sides of the road with a vehicle traveling 50 mph (80 kph) with the engine switched off.

Keep in mind that these are rough estimates, and your actual cost may be higher or lower depending on the specific make and model of your vehicle, your location, and the other factors we discussed earlier. It's always a good idea to get a detailed quote from your mechanic before agreeing to any repairs.

Improvements on road and tire design have reduced the total noise level of tires in the past decade. In the highway and road markets, transitioning from common stone to porous asphalt reduced the noise level. Breakthroughs on prediction tools and optimizing the tire pattern by computer have driven tire noise to the lowest levels ever.

The frequency of structure-borne and airborne noises shifts as the dominant inside noise as the result of changes in the vehicle’s speed. At lower frequency, normally at lower speeds, the structure-borne noise is the dominant type of noise. At a higher frequency range, normally at higher speeds, the airborne noise is the dominate type of noise. Structure-borne noise is normally around 160 Hz and is influenced by tire construction. Airborne noise is normally around 1,000 Hz and is influenced by a tire’s tread pattern. Table 1 on page 23 shows the type of interior noises, as well as frequency range and the area of the tire that affects the noise. External noise transmits at any speed and increases as the vehicle speed increases. This means that as speed increases, overall noise increases, which includes noise from a vehicle’s tires, powertrain and aerodynamics. Figure 3.

The number of black waves in the speaker reflects the noise severity of the tire. A speaker with one black wave is normally an indication of a quiet tire. A speaker with two black waves demonstrates a tire with a moderate level of noise, while three waves coming out of the speaker is an indication of a noisy tire. Noise levels are established by size, with narrower tires challenged by lower targets than wider tires. While the dB level is quantifiable, the tire’s ability to comply with EU regulations (number of sound waves) can be compared only between tires of the same size.While there is no country-wide tire noise regulation in the U.S., most of the tires sold here carry the European E-mark, which is an indication of lower noise levels. Final Thoughts Tire noise is a very complex matter normally managed by a team of experts within tire companies who are experienced with NVH (noise, vibration and harshness). Because tire noise levels change internally and externally with the speed of the vehicle and the transfer through different sources, detecting and improving tire noise difficult. However, with the advancement of prediction tools and a better understanding of noise sources, today’s tires are much quieter than their predecessors. Developing the next level of noise reduction will be challenging, but the industry is committed to providing the quietest tire—both internally and externally—to the market.

One of the most noticeable signs of a failing wheel bearing is a loud, constant humming, rumbling or growling noise coming from the wheel area. The noise may get louder or change pitch as you accelerate, decelerate or turn. If you suspect a bad bearing, try swerving gently from side to side in an empty parking lot. If the noise gets louder when you turn one way and softer when you turn the other way, it's likely a bearing issue.

While those improvements significantly reduced overall vehicle noise, tires remain the focal point of the majority of noise generation at higher speeds, so constant improvement is required. In order to improve a tire’s noise level, it is important to understand a tire’s noise mechanism, both internally and externally.

When talking about vehicle noise, we typically refer to interior noise, or noise we hear inside of the vehicle cabin. However, there are two types of noises generated by vehicles.

Wheel bearings replacementcost

Wheel bearings are generally considered a wear item and are not typically covered under a vehicle's basic factory warranty. However, some extended warranties or service contracts may include coverage for wheel bearing replacements, so it's worth checking your specific policy to see what's included.

However, rear-wheel drive vehicles may put more strain on the rear bearings, especially if they're frequently used for towing or hauling heavy loads. If you have a bad rear wheel bearing, you may end up paying more for the replacement due to the added complexity of the job.

Expect to pay anywhere from $50 to $140 per hour for labor, with most wheel bearing replacements taking between one and three hours to complete. If your vehicle has a more complex suspension setup or if the bearings are particularly difficult to access, labor costs could be higher.

Structure-borne noise is normally around 160 Hz and is influenced by tire construction. Airborne noise is normally around 1,000 Hz and is influenced by a tire’s tread pattern. Table 1 on page 23 shows the type of interior noises, as well as frequency range and the area of the tire that affects the noise.

Remember, even with the best maintenance, wheel bearings are still a wear item that will eventually need to be replaced. Staying on top of regular inspections and addressing any issues promptly can help you avoid more costly repairs and keep your vehicle running safely and smoothly.

Now that you have a basic understanding of wheel bearings, let's look at the various factors that can impact the cost of replacing them:

If you're experiencing wheel bearing issues and your vehicle is still under warranty, it's best to contact your dealer or warranty provider to discuss your options. They may require an inspection to determine the cause of the failure and whether it's eligible for coverage.

The cost of the replacement wheel bearing assembly itself can range from $100 to $800 or more, depending on the quality and brand. OEM bearings are typically more expensive than aftermarket ones, but they may come with a better warranty and assurance of proper fitment.

So how do you know if you need a wheel bearing replacement in the first place? Here are some common symptoms of a bad wheel bearing to watch out for:

In some cases, your mechanic may recommend additional services or repairs along with the wheel bearing replacement. For example, if the bearing failure caused damage to the brake rotors, CV joints, or other suspension components, you may need to replace those parts as well. This can significantly increase the overall cost of the repair.

The make, model and year of your vehicle play a significant role in determining the cost of a wheel bearing replacement. Luxury and high-performance vehicles often use higher-quality, more expensive wheel bearing assemblies than economy cars. Additionally, some makes and models may require specialized tools or procedures to replace the bearings, which can drive up labor costs.

Interior noise is transmitted inside of the vehicle through its structure and via air. Airborne noise consists of the progressive movement of mass particles (vibrations) and is transmitted in the form of soundwaves at the speed of sound to the vehicle cabin. Structure-borne noise is transmitted through the body of the vehicle through the tire. Exterior noise is transmitted outside through radiation and sound waves. See Figure 2 that illustrates the difference between structure-borne noise, airborne noise and tire noise radiation.

As wheel bearings wear out, they can cause excessive play and looseness in the wheel, which translates to vibration in the steering wheel, floorboard or seats. You may feel the vibrations at all speeds, or only at certain mph ranges. If the vibration changes when you turn left or right, that's another indicator of a potential bearing problem.

When a wheel bearing is damaged, it can cause the wheel to wobble or tilt at an angle, which leads to uneven or rapid tire wear. If you notice that one tire is wearing out much faster than the others, or if the tread is wearing unevenly across the width of the tire, it could be a sign of a bad bearing.

However, like any other mechanical component, wheel bearings can wear out over time due to age, mileage, driving habits, and exposure to the elements. When they fail, it compromises the wheel's ability to turn freely, which creates a host of problems ranging fromannoying to downright dangerous. That's why it's crucial to address wheel bearing issues promptly.

As you can imagine, the quietest tire is a smooth tread where no impact between the tread blocks and the road exists. The closer the tire pattern gets to a completely smooth tire, the quieter the tire gets. Tire manufacturers were able to reduce overall tire noise by 5 to 8 dB in the past 10 years. In some cases, modern tires have only 2-3 dB higher noise than smooth tires.

For most people, it's safer and more cost-effective to leave wheel bearing replacement to the professionals. A qualified mechanic will have the knowledge, tools and experience to do the job correctly and efficiently, and they can also spot any related issues that may need to be addressed.

Incorrectly installed or adjusted wheel bearings can fail prematurely or cause other problems like uneven tire wear, vibration and steering issues. In some cases, a botched bearing job can even lead to a wheel separation or loss of control, which could have catastrophic consequences.

In rare cases, a wheel bearing failure may be caused by a manufacturing defect or faulty material, in which case it may be covered under the vehicle's powertrain warranty. However, this is unlikely unless the failure occurs very early in the vehicle's life and is not related to any external factors like accidents, modifications or abuse.

External noise is generated outside a vehicle and affects noise pollution, impacting pedestrians, cyclists and near-by residents. The majority of external noise stems from the tires rolling on the road surface, but it can also be generated by the exhaust, intake system or engine. As external noise impacts urban life, legislative bodies across the world are sensitive to it. The goal of most government agencies is to minimize external vehicle noise to improve overall urban life. Noise level limits have decreased over the years for almost all vehicle components, including tires.Driving at lower speeds, smoother/finer material in road surfaces, smaller wheels, narrower tires and quieter engines (i.e. electric-powered engines) can improve vehicle external noise. While those are good measures, designing components such as tires to perform at an optimal noise level is the ultimate solution. Internal Noise Internal noise refers to the noise the driver and passengers experience inside the vehicle cabin. The issue of internal noise and how it negatively affects drivers and passengers is something that is a focus for OEMs. Luxury brands, driven by their quiet, comfortable ride objectives, have a very high standard on noise limit. Key sources of interior noise are engine noise, tire/road noise and wind noise, as well as noise from miscellaneous sounds in the interior. The application of sound-absorbing materials throughout the vehicle, thicker noise-reducing glass, quieter engines (and better sound-proofing between the engine and the cabin in the so-called firewall), softer suspensions with smaller wheels and narrower-width tires can all help reduce internal noise. However, like external noise, designing various components to operate at a lower noise level would be the ultimate solution. Tire and Road Interaction Improvements on road and tire design have reduced the total noise level of tires in the past decade.

Another key factor is whether you need to replace a front or rear wheelbearing. In general, front wheel bearings tend to wear out faster than rear bearings because they carry more of the vehicle's weight and are subjected to greater stress from turning and braking. As a result, front wheel bearing replacement costs are often higher.

Some cheaper, low-quality bearings may not last as long or perform as well as premium options, so it's important to choose a reputable brand and supplier. Don't just go for the lowest price; consider the long-term value and reliability of the parts you're putting on your vehicle.

Internal noise refers to the noise the driver and passengers experience inside the vehicle cabin. The issue of internal noise and how it negatively affects drivers and passengers is something that is a focus for OEMs. Luxury brands, driven by their quiet, comfortable ride objectives, have a very high standard on noise limit. Key sources of interior noise are engine noise, tire/road noise and wind noise, as well as noise from miscellaneous sounds in the interior.

It's also a good idea to have your vehicle's alignment checked after replacing a wheel bearing, as misalignment can cause premature wear on the new bearings and other tire components. An alignment typically costs between $50 and $150, depending on the type of vehicle and the complexity of the adjustment.

If you experience any of these symptoms, it's best to have your vehicle inspected by a qualified mechanic as soon as possible. Ignoring a bad wheel bearing can lead to more extensive damage and costlier repairs down the road, not to mention the safety risk of a potential wheel separation or loss of control.

Affected by pandemic supply chain disruptions and the uptick in sales of all-weather tires, the winter tire market in the U.S. has been largely flat in recent years.

In summary, the cost of a wheel bearing replacement can vary widely depending on your vehicle make and model, labor rates in your area, and the specific type of bearing assembly required. On average, you can expect to pay anywhere from $300 to $800 per wheel, with some luxury or heavy-duty vehicles costing even more.

The main job of wheel bearings is to enable the wheel to rotate smoothly with minimal friction. They support the entire weight of the vehicle while in motion. Most modern cars, trucks and SUVs have sealed wheel bearing assemblies that are pre-lubricated at the factory and designed to last for the lifetime of the vehicle under normal driving conditions.

While it is possible to replace wheel bearings yourself if you have the right tools and experience, it's generally not recommended for the average DIY mechanic. Wheel bearing replacement requires specialized equipment like a hydraulic press, torque wrench and bearing puller, as well as a clean, well-lit workspace and a good understanding of vehicle suspension and braking systems.

If you suspect a bad wheel bearing, don't ignore the problem or put off the repair. A failing bearing can cause serious safety issues and lead to more extensive damage if left unchecked. Have your vehicle inspected by a trusted mechanic as soon as possible to diagnose the issue and get a detailed quote for the repair.

External noise transmits at any speed and increases as the vehicle speed increases. This means that as speed increases, overall noise increases, which includes noise from a vehicle’s tires, powertrain and aerodynamics.

There are different sources in a vehicle that create noise, both internally and externally. Overall, the components that contribute most to vehicle noise include the tires, engine, powertrain, exhaust, intake system, in addition to the aerodynamics of the vehicle. Figure 1 shows the significant effect of each element on vehicle noise. As you can see, tires, by far, are the largest contributor to total noise, followed by the exhaust and intake systems. Therefore, improving tire noise can improve the total vehicle noise overall.

In some cases, a faulty wheel bearing can damage the sensors that monitor wheel speed for the anti-lock braking system (ABS). If you see the ABS warning light illuminate on your dashboard, it could be related to a bearing issue. A scan tool can help pinpoint the exact cause of the ABS fault.

In some cases, modern tires have only 2-3 dB higher noise than smooth tires. While those improvements significantly reduced overall vehicle noise, tires remain the focal point of the majority of noise generation at higher speeds, so constant improvement is required. In order to improve a tire’s noise level, it is important to understand a tire’s noise mechanism, both internally and externally. Figure 2: Types of Tire Noises; Source: Yokohama Tire Tire Noise Mechanism Interior noise is transmitted inside of the vehicle through its structure and via air. Airborne noise consists of the progressive movement of mass particles (vibrations) and is transmitted in the form of soundwaves at the speed of sound to the vehicle cabin. Structure-borne noise is transmitted through the body of the vehicle through the tire. Exterior noise is transmitted outside through radiation and sound waves. See Figure 2 that illustrates the difference between structure-borne noise, airborne noise and tire noise radiation. The frequency of structure-borne and airborne noises shifts as the dominant inside noise as the result of changes in the vehicle’s speed. At lower frequency, normally at lower speeds, the structure-borne noise is the dominant type of noise. At a higher frequency range, normally at higher speeds, the airborne noise is the dominate type of noise. Structure-borne noise is normally around 160 Hz and is influenced by tire construction. Airborne noise is normally around 1,000 Hz and is influenced by a tire’s tread pattern. Table 1 on page 23 shows the type of interior noises, as well as frequency range and the area of the tire that affects the noise. External noise transmits at any speed and increases as the vehicle speed increases. This means that as speed increases, overall noise increases, which includes noise from a vehicle’s tires, powertrain and aerodynamics. Figure 3. European Tire Label; Source: European Parliament External Noise and Regulation As discussed earlier, external noise impacts urban life. Noise regulation is different in each country. The European Union (EU) tire labeling regulations for passenger car and light truck tires, for example, went into effect November 1, 2012. This information helps consumers make a conscious decision during the tire purchase (see the European Tire label in Figure 3). The label consists of three criteria: wet braking (A), fuel efficiency (C) and pass-by noise. While a lot of people think the noise level on the label is an indication of indoor noise, it actually indicates noise pollution or external noise measured by a pass-by noise vehicle test. A tire rated one wave is half as noisy as a tire rated with two waves. Pass-by noise is measured from the sides of the road with a vehicle traveling 50 mph (80 kph) with the engine switched off. The number of black waves in the speaker reflects the noise severity of the tire. A speaker with one black wave is normally an indication of a quiet tire. A speaker with two black waves demonstrates a tire with a moderate level of noise, while three waves coming out of the speaker is an indication of a noisy tire. Noise levels are established by size, with narrower tires challenged by lower targets than wider tires. While the dB level is quantifiable, the tire’s ability to comply with EU regulations (number of sound waves) can be compared only between tires of the same size.While there is no country-wide tire noise regulation in the U.S., most of the tires sold here carry the European E-mark, which is an indication of lower noise levels. Final Thoughts Tire noise is a very complex matter normally managed by a team of experts within tire companies who are experienced with NVH (noise, vibration and harshness). Because tire noise levels change internally and externally with the speed of the vehicle and the transfer through different sources, detecting and improving tire noise difficult. However, with the advancement of prediction tools and a better understanding of noise sources, today’s tires are much quieter than their predecessors. Developing the next level of noise reduction will be challenging, but the industry is committed to providing the quietest tire—both internally and externally—to the market.

A severely worn wheel bearing can make your vehicle feel loose, sloppy or unstable when steering, especially at higher speeds. You may notice the car wandering or pulling to one side, or the steering wheel may feel wobbly or hard to control. These symptoms can also be caused by alignment issues or worn suspension components, so it's important to have a mechanic diagnose the problem.

As external noise impacts urban life, legislative bodies across the world are sensitive to it. The goal of most government agencies is to minimize external vehicle noise to improve overall urban life. Noise level limits have decreased over the years for almost all vehicle components, including tires.Driving at lower speeds, smoother/finer material in road surfaces, smaller wheels, narrower tires and quieter engines (i.e. electric-powered engines) can improve vehicle external noise. While those are good measures, designing components such as tires to perform at an optimal noise level is the ultimate solution.

Before we talk dollars and cents, it's important to understand what wheel bearings are and the critical role they play in your vehicle's performance and safety. Wheel bearings are small metal balls or tapered rollers enclosed in a metal ring called a race. They inside a hollow piece of metal called a hub, which attaches to the vehicle's suspension on one side and the brake disc or drum on the other.

In this article, we will briefly review the sources of vehicle noise, types of vehicle noise, tire and road interaction, the tire noise mechanism, and, finally, some of the regulations around tire noise.

If you've started hearing strange noises coming from your car's wheels or noticed unusual vibrations while driving, it may be time to consider a wheel bearing replacement. But before you head to the mechanic, you're probably wondering: how much is this going to cost me? Don't worry, we've got you covered with all the details on front and rear wheel bearing replacement costs, what factors influence the price, and how to tell if your bearings have gone bad. By the end of this article, you'll be equipped with the knowledge to make an informed decision about getting your wheel bearings replaced. Let's dive in!
