Squealing Or Grinding Noise To confirm it, change the speed of the vehicle. If the noise becomes worse the faster you drive, then it's almost certainly a bad wheel bearing. If the noise remains the same, then the issue may be the tires instead.
What causes a loud humming noise while driving?
A bad wheel bearing is one of the more serious issues that cause tire noise. When the wheel bearing in your tires is damaged or deteriorating, it produces a soft humming sound or grinding noise when you change lanes.
How do you check wheel bearings while driving?
You can test this by gently swaying your car while driving slowly. If the noise lessens when you sway right, then the damaged bearing is likely on a left wheel bearing. If it lessens when you sway left, a right wheel bearing is likely broken.
How expensive is it to replace a wheel bearing?
The national average is about $350 to fix the wheel bearings at one wheel. As you might imagine, however, luxury brands cost more. Please note: If the wheel bearings need replacing at one wheel, you don't necessary need to replace the bearings at the other wheel on the same axle.
Does wheel bearing noise stops when braking?
The frequency of the noise will also change in proportion to vehicle speed, but will often go away or change when the brakes are lightly applied. Noise that only occurs when braking is likely a brake problem such as worn pads, not a bad wheel bearing.
Is it safe to drive with wheel bearing noise?
Grinding noises or humming noises from your car's wheel could be connected to a number of different causes, including wheel bearing problems—especially if you notice the sound changes in relation to speed. If there is a problem with your wheel bearing, it will be unsafe to drive it.
How to tell if a wheel bearing is bad?
Wheel bearing failure can, in some cases, be catastrophic where the entire bearing disintegrates. Fortunately for everyone, there are usually plenty of warning signs before that happens. One of the most common symptoms of a failing wheel bearing is noise.
How does load affect wheel bearings?
In other words, when you turn left, the weight of the car is shifted to the right side of the vehicle. Even though you have the entire suspension system to balance out this weight distribution, a considerable amount of load is exerted on the wheel bearing itself.
What are the components of a bearing?
Most bearings have three main components – the outer and inner race and a set of precision machined metallic balls. The outer race is bolted to the wheel hub and suspension, while the inside race is connected to the CV joint and your driveshaft. The bearings in between allow the inner race to spin freely while the outer race remains static.
Can you jack up a car to check for noise?
Once you’ve tested for noise and narrowed down its source, it’s time to jack up the car and confirm your findings. Before we get any further, a quick word of advice – make sure that your vehicle is securely lifted and suspended off the ground.
How to tell if wheel bearings are bad?
Without working wheel bearings, your car won’t be going anywhere fast. One of the most common signs of a bad wheel bearing is a grinding or squealing noise. If you can no longer bear the sound of your wheel bearings, you’re in the right place.

Why do tires wear unevenly?
Uneven Tire Wear. Bad wheel bearings can cause the tires to wear unevenly, across either the inside or the outside of the tire. It’s easier to spot this when the wheel is off, as you can take a proper look at the inside of the tire.
Why do wheel bearings need to be installed correctly?
Wheel bearings must be installed correctly to ensure they’re seated tightly in the wheel hub. Incorrect installation can allow moisture and dirt to enter the bearing, which causes premature wear and eventually failure.
What is the purpose of petroleum based lubricant in wheel bearings?
A petroleum-based lubricant is used to reduce pressure and friction, but unfortunately, this lubricant doesn’t stop water from getting into the bearings.
What causes a car's wheel to fail?
There are many parts to your car’s wheel system: wheel bearings, lower arms, wheel hubs, knuckle arms, shock absorbers, and tires. Unbalanced tires or wheels can cause premature wear to these important components, putting even more stress on the wheel bearings and causes them to fail prematurely.
How much does it cost to replace a rear wheel bearing?
You can expect to pay around $230 to $480 for both parts and labor for both rear wheel bearings. Or, for just a single rear wheel bearing replacement, it’ll cost around $115 to $240.

So, if the stress that’s placed upon them is increased for a prolonged period of time, then this can result in the bearing wearing out prematurely.
Why are wheel bearings not designed to absorb side impacts?
This is simply because they’re not designed to absorb side impacts that occur if your vehicle slides into a curb. If you’ve had a side impact similar to that of sliding into a curb, have your suspension and wheel bearings assessed to ensure you’ve not damaged them.
How long do wheel bearings last?

Does salt water damage bearings?
A buildup of salty sea water in your bearings can be detrimental to the longevity of the bearing itself. As salt water works its way into the bearing housing, not only does it wash out the grease contained inside, but it will also begin to work it’s magic of corroding the internals of the bearing.
How to tell if wheel bearing is bad?
A: Noise is the most common symptom of a bad wheel bearing. However, there are other potential signs as well, such as vibrations while driving. At low speeds, you will be able to feel the vibrations, while at higher speeds, they’ll manifest as humming sounds.
Why is it important to have wheel bearings inspected?

They are also prone to abuse, which is why it’s essential to know the warning signs. But before we go deeper into bad bearings, symptoms, impact, and costs, it’s equally important to understand what it is.
What is a wheel bearing?
A wheel bearing is a set of steel balls held together in a metal ring, called a race . At the center of your wheels, there is a hollow piece of metal, called a hub. The wheel bearings fit tightly inside this hub, and ride on a metal axle shaft, helping reduce friction when the wheel spins.
Can you drive a car if your bearings are worn out?
A: No. It can, in fact, be very dangerous to drive if one of your bearings is worn out, especially since it may cause the wheel to stop while driving. Additionally, a damaged wheel bearing puts a lot of stress on the hub, the CV joint, and the transmission itself.
