What happens if a rear wheel bearing goes out?
A bad wheel bearing can cause the brake rotor to wobble, which shoves the caliper piston back into its bore so that when you apply the brakes, you have unexpected pedal travel as a result – making it harder to stop or causing the vehicle to pull unexpectedly to one side – never a good thing in traffic.
What happens if you don't replace rear wheel bearings?
If you ignore bad wheel bearings, your wheel could stop working while driving, or you could have issues steering your car. In addition to the danger, it can put a lot of strain on other parts of your vehicle, such as the hub, CV joint, and transmission.

Can a bad wheel bearing cause brake problems?
We found significant play in the bearing, which can lead to a soft brake pedal. Brake rotors are held in alignment by wheel bearings. If you have a faulty or loose wheel bearing, the rotor will wobble on its axis. This wobble causes the rotor to push the caliper piston into its bore (See Image 2).
Is replacing a wheel bearing a big job?
A front or rear wheel bearing replacement isn't a huge job, however it is fairly complex and can be time-consuming even for the most experienced mechanics.

How does a wheel bearing work?
Along with grease, the bearing rotates in-tandem with the wheel’s rotation, the rolling motion of the balls allowing the wheel hub to rotate as freely as possible. The wheel bearing is housed within the hub assembly, providing the static connection with the hub carrier through an outer ring or ‘racer’.
Why are wheel bearings important?
Wheel bearings play an important role within the drivetrain of any vehicle, as they provide the first connection between the moving and static areas of the car. A bearing – in its simplest form – is a friction reduction device placed within something like a wheel to aid efficiency of rotation. This is achieved as rolling produces much less friction ...

What does a wheel bearing do?
The wheel bearings of your car take a lot of abuse. They support the entire weight of the car when it’s running. That aside, the wheel bearings have to shoulder extra pressure while negotiating bad roads and the occasional curb, when the lateral force on the corners makes your wheels spin thousands of revolutions each minute.
What does it mean when your tires are worn out?

Why does my steering wheel make a rumbling noise?
For defective wheel symptoms the vibration is emitted while driving straight at a constant speed. The noise increases while turning the steering wheel to the right or left. The rumbling noise comes from opposite of the side which is defective.
What does it mean when your wheel is popping?
A snapping, popping, or clicking sound indicates that you are driving with a bad wheel bearing. It means that the outer CV-joint of the wheel is damaged or worn out. But such sounds may also indicate inadequate clamping or excessive bearing endplay. The noise is usually heard while taking a sharp turn. 2.
Why are my tires wearing out?
There could be several causes for an abnormal wearing of tire. Misalignment, damaged suspension components, and improper inflation lead to tire wear. While extreme wheel bearing looseness or wear could lead to abnormal worn out tires, it’s usually related to various other failures.
Why is ABS bad?
ABS Failure. In some extreme cases, external or internal sensors of a wheel could be damaged because of the excessive movement from too much endplay. ABS failure results from a major mechanical damage. In brake systems where the sensor is externally mounted, corrosion could lead to damage.
What happens if your wheel bearing fails?
If your wheel bearing fails, it can cause the wheel to stop while you are driving or possibly even to fall off. At the very least, before a wheel falls off, a failed wheel bearing can/will cause significant damage to your vehicle, so it’s very important to keep an eye on these and keep them maintained.
How long do wheel bearings last?

Why do wheel bearings need grease?
Wheel bearings require grease to lubricate them, with a seal keeping the grease in the bearing. The seal also acts as a barrier against dirt and debris that can cause corrosion. The seal is essential to the durability of the wheel bearing. Wheel bearings allow the wheel to spin rapidly without too much friction.
Why do you need to have your wheel bearings checked?

Wheel bearings play a vital role in keeping the wheel attached to your vehicle . Without wheel bearings, your wheel is essentially unattached. This can be very dangerous, especially while traveling on highways at high speeds.
What does it mean when your car is playing in the wheel?
Play in the Wheels – Most often this symptom will be identified by a technician . When your vehicle is up on the lift, a technician will grab the wheel on either side and attempt to rock it back and forth. If the wheel assembly wobbles back and forth, worn out wear bearings are likely the cause.
What is the purpose of a wheel bearing?
As the wheels spin, they create friction and heat. Wheel bearings help to reduce the friction, heat and protect the wheels and tires. The wheel bearing lies inside of the hub assembly.
What happens when a tire is worn?
Vibrations and Shaky Ride – Failed wheel bearings produce an unfavorable ride. You’ll experience vibrations and tremors as you travel as a result of an increase in friction in the wheels causing them to change position.
Why does my steering wheel shake?
Typically, when wheel bearings are the cause of such vibrations, you feel the shaking at lower speeds . The shaking will only get worse and may even occur while accelerating if not addressed.
What happens when a wheel bearing fails?
Progressive damage: Once a wheel bearing begins to fail, it will affect other components. The bearings won’t allow the wheel to turn freely, which exacerbates the problem. It also puts stress and strain on the hub, the CV joint, the axle, and the transmission.
What happens if you don't replace a wheel bearing?
Ultimate damage: If you don’t replace a damaged wheel bearing before it fails completely, the wheel will completely seize up. If this happens while you’re driving, the results can be catastrophic. This is not a component to take chances with.
How to tell if wheel bearings are bad?
Some things to watch out for include: 1 Roaring: The most common symptom of a failing wheel bearing is a roaring sound from the affected wheel while you’re driving. It may become more pronounced during turns as the car’s weight shifts and a different load is placed on the wheel. In some instances, you’ll only hear a noise under specific driving conditions (it depends on where the wear in the race is occurring). If you notice a roaring sound from one of the wheels, it’s vital to have it inspected as soon as possible. 2 Wheel play: If you grab the tire by the top and bottom edges and wiggle it up and down, movement should be very minimal or nonexistent. However, if you notice a lot of movement, it means that your bearing is nearing the end of its life. 3 Progressive damage: Once a wheel bearing begins to fail, it will affect other components. The bearings won’t allow the wheel to turn freely, which exacerbates the problem. It also puts stress and strain on the hub, the CV joint, the axle, and the transmission. 4 Ultimate damage: If you don’t replace a damaged wheel bearing before it fails completely, the wheel will completely seize up. If this happens while you’re driving, the results can be catastrophic. This is not a component to take chances with.
