Rear Wheel Bearings: A Comprehensive Guide About Rear Wheel Bearings

Post date:



Security is the primary priority for your car, whether you’re driving independently or with your loved ones. Sometimes, the essential things can lead to grave and irreparable injury. It is essential to conduct regular checks on your car. One thing that could cause grave damage is defective front or rear wheel bearings.

Wheel bearings are usually indications that indicate it’s the right time to replace them. The most obvious signs can be seen in noises like chirping, squealing, or growling. In this situation, it is clear that ignoring the sound isn’t the answer since wheel bearings play an essential part in the performance of your car.

What causes the rear wheel bearings to make noise?

It isn’t easy to know how long car parts will last, as other elements such as storage, weather, and other factors can affect their longevity. If you’re looking to determine how long the worn-out wheel bearing lasts, it is the initial step to pinpoint the noise it’s making or any other unusual behavior.

Soft or loud noises at the time of turning

Examine if you can hear the sound when the vehicle turns by conducting a test. Make some left and right turn. If your turn is made, the outside wheels will be working the hardest, so the excellent side bearing won’t make noise as you turn in this direction. However, when you rotate to the side of the damaged bearing, the noise is much louder. For instance, if the noise is less as you turn to the right, that is a sign that your left-hand wheel bearing has been damaged, and reverse.

Continuous whining and loud grinding noise

Are you hearing a loud, continuous grinding and whining sound while the vehicle moves? Do you notice that it gets more pronounced as you speed up? If this happens, the wheel bearing may be damaged or could cause your differential.

The sound of a car chugging along on uneven roads

If you hear an unending clunking sound on uneven roads and a constant clunking noise, you’ve got an issue. The constant rumble caused by the road could create a louder sound and could result in the bearing breaking.

The steering wheel shakes

Does the car wheel make a sound when turning or speeding up? If you notice that increasing speed causes your steering wheel to shake, then it could be that a leaky seal could be the cause of the vibrations. The seal on the wheel bearing is designed to prevent foreign elements from getting to the inside of the bearing to function correctly.

A lot of play on the steering wheel

A worn-out wheel bearing could also result in excessive play on the wheel. This could lead to more sloppy and uncontrolled steering, which can be dangerous when driving. To find out if there’s too much play on the steering wheel, move the wheel in a circular motion at the 3 and 9 o’clock locations or the 6-12 clock places. If your wheel is loose in any location, the wheel bearing is damaged and requires replacement.

Abs System failing

Sometimes, the ABS sensor embedded in the wheel bearing may suffer damage due to the force of moving or corrosion, stones, or other dangers. Any problems with your brake system must be investigated immediately. This could help save your life and the lives of those closest to you. After identifying the source of the noise or strange feeling, can you know how long you will be able to keep using your vehicle that has a loud wheel bearing? In the end, the sound you hear emanating from your wheel bearings indicates that it’s time to get a replacement.

If you feel or hear the sound, we suggest taking your wheel bearings to be looked at as soon as you can. To know why we recommend examining it in the shortest time possible, we’ll explain the wheel bearings, how they function, and why using a loud one could cause harm.

Rear Wheel Bearings

The term “rear wheel bearing” is used to describe wheel bearing as a component that connects the wheel to the axle. It’s a set made of steel balls joined by an iron ring. It is constructed from toughened steel that can stand up to years or months of usage based on specific conditions. The wheel bearing sits in the middle of the wheel, which is a hollow piece of metal known as the hub.

The wheel then rests on an axle shaft made of metal which allows the wheel to move without a hitch while reducing friction as the wheel turns. Wheel bearings can also support the car’s weight while it is moving. They are used constantly for braking, accelerating, or turning. That is why they have to be in top operating and good working order.

What is a bearing? What is its purpose in the car?

How long will wheels last after they make noise?

Determining how long wheel bearings last is a challenge, as we have mentioned earlier, and other elements could play a significant role in determining the durability of their bearings. But, a wheel bearing could last anywhere between 136,000-and 160,000 kilometers, which is equivalent to 85,000-100,000 miles. Be aware that the condition of a wheel bearing and the vehicle’s operation is also a factor in determining the life span of a wheel bearing. Therefore, there is no definitive answer since each wheel bearing may last longer than the other ones.

Get it checked immediately if you notice or feel your vehicle is acting strange. A worn-out brake pad could make the same noise as a worn-out wheel bearing. Therefore, you should ensure that it’s not the brake pad that’s worn out. However, sounds coming from your car could result from a faulty lifter and a catalytic converter rattling.

Why do worn-out wheel bearings create noise?

Like all auto components, wheel bearings, even though they’re simple components, can be prone to failure from time to time. The reason why broken wheel bearings create noise?

Here are a few of the reasons why:

Incorrect Installation

If you’re a do-it-yourself mechanic, an incorrect installation could cause the wheel bearing to sound. If you reuse nuts, bolts, pins, seals, or bolts rather than replacing them with brand new ones, they could create a situation where your wheel bearing is acting differently. It is best to buy new products and not reuse them. However, when you use an impact wrench or hammer to strike anything inside or onto the exterior of your wheel, it could also result in the bearing on your wheel breaking in a short time. They will increase the chance that your wheel bearing will fail when required and place your safety at risk.

Roads that have poor infrastructure

The impact damage caused by driving on roads with lots of potholes could shorten the lifespan of any tire bearing. The speed bumps you drive over and hitting the curb can cut down the lifespan of a wheel bearing.

Poor Quality Wheel Bearings

Safety is the top priority while driving, now isn’t the time to cut corners. Wheel bearings are constantly under pressure and are in constant use. In this regard, you must ensure you’ve got an axle bearing made of the finest quality materials that will endure the stress that puts on it.

Conditions for Driving

Modern wheel bearings are with seals to block out moisture and other debris. The seals stay in the high-temperature grease wheel bearings required to function. The deep water or dirt or other substances like road salt could be able to pass through the seals and can cause damage to the bearings of the wheel.

Modifications to the vehicle

There might come the point when you’re looking to upgrade your car and need tires with thinner thread walls, larger or broader rims. You may also want stiffer shock absorbers and suspension springs. Although they may give your vehicle a better look or feel, they put excessive pressure on the wheel bearing. Stay to the manufacturer’s recommendations for your specific vehicle to prevent this from happening. So that your wheel bearing will function just as it should and last for a long time. Other causes are the possibility of overheating because of friction or insufficient lubricant, uneven tires, etc.

How much will it cost to change the bearings on the back wheels?

Rear wheel bearings replacement typically costs between $100 and $347, based on whether you go to a professional or do it yourself. Taxes, fees, and your specific make and model are not considered in this price range, which is based on median incomes for all automobiles.

The most common signs of damaged rear wheel bearings

1. Side pulling that is abnormal while applying the brake.

It is typically an indication of a malfunctioning equalizer or caliper, but worn bearings could cause it.

2. Clicking, snapping, or popping sound.

These sounds will be heard as you turn sharply or turn.

3. Wobbly wheels

The damaged bearing of your wheel could cause your wheel to wobble as the bearing is necessary for connecting the wheel to the vehicle. The wheel may wobble and eventually slide off if it wears out or becomes damaged. Once you’ve figured out a few signs and the signs to look out for, you will be able to determine the bearing that needs to be replaced.

What happens if a rear wheel bearing goes out while driving?

If a rear wheel bearing goes out while driving, it can have serious consequences for the vehicle and its occupants. The wheel bearing is responsible for allowing the wheel to spin smoothly, and it also helps to support the weight of the vehicle. When a rear wheel bearing fails, it can cause the wheel to become loose and wobble, which can lead to a loss of control of the vehicle. This can result in a dangerous situation, especially at high speeds.

Additionally, a failed rear wheel bearing can cause excessive wear and damage to the tires, suspension components, and other parts of the vehicle. It can also generate a loud, grinding noise that can be heard while driving, which is a clear sign that something is wrong with the vehicle. In some cases, a failed rear wheel bearing can cause the wheel to lock up, making it impossible to steer or control the vehicle, which can lead to an accident.


Front and rear wheel bearings are the most crucial part of any vehicle. You should take special care of the wheel bearing and change them or fix them as soon as you can do this. This article helps in understanding the behavior of bearing in detail. Take specialist guidance before doing anything related to wheel bearings.
