Wheel bearings are a set of steel balls contained in a lubricated metal ring located in the hub. They support the weight of your vehicle and allow the wheels to rotate freely while you drive. In normal conditions, the bearing accomplishes this without making any excessive noise. If the grease lubricant escapes the bearing or debris as water or sand enters it, the bearing will wear out and fail quickly.

Friction can never be truly eliminated, only reduced, and over time wheel bearings themselves wear out, though the most common reason for wheel bearings to fail is that their seals let the grease out, and water and grit in, damaging the balls and tapers.

Regular servicing and the annual MOT test should pick up a failing bearing, which will often reveal itself by the wheel not spinning as smoothly as it should when the car is in the air.

That being said, when you are moving, the sound will not cut in or out. If you only hear a noise when you are accelerating, decelerating, or braking, there may be another drivetrain issue.

Frontwheel bearingnoise symptoms

Each wheel on your car has a wheel bearing, and this component connects the wheel to the axle of the car. A wheel bearing comprises a set of ball bearings (small, smooth metal balls) or metal tapers (small, smooth metal cylinders) held together inside two rings of metal, surrounded with grease.

What does abad wheel bearing soundlike at high speed

Being part of the hub assembly, noise caused by a bad wheel bearing will only occur when you are moving. The sound may increase or decrease when you pick up speed or go around a turn. Paying attention to changes in noise or volume when going around corners. These changes can give insight into which side has gone failed. A bad wheel bearing can make any of the following noises depending on the cause or severity of the failure:

The short answer is no. You should not drive your vehicle if you believe you have bad wheel bearing. The long answer is yes, but with the understanding that driving with a failed or failing wheel bearing can lead to serious safety issues as well as severe damage to your car.

When the wheel turns it does not rotate directly on the axle; rather, it rotates around the wheel bearing, which allows it to turn smoothly. Wheel bearings exist to reduce friction.

And while cars are complex machines that can emit strange noises from all manner of places and for a number of reasons, wheel bearings are components that tend to make a noise when they are defective.

Wheel bearingnoise when accelerating

If the noise you are hearing continues when you come to a stop, it is likely not caused by a bad wheel bearing. To produce noise, the wheels of your car need to be rotating.

This is an extreme case, but if you drive on a bad wheel bearing for long enough, the wheel could come off. If this were to happen on the freeway or at high speeds, it could be catastrophic for you, your car, and other drivers.

Wheel bearings are replaced in one of two ways: either a press is used to force the bearing out of the wheel hub, and force a new one in, or the entire hub assembly is replaced. Whichever method is used, you’ll need to know what you’re doing.

How to fixbad wheel bearing

A lot of the time, your car may not feel any different when the bearing is making noise. It’s easy to overlook or put off an issue that is not directly impacting your daily driving.

You may also detect that the car pulls to one side, or the tyres may wear unevenly – though this can also be a sign that the wheels need realignment.

Hearing any abnormal noise while you drive is stressful. With so many moving parts making up your car, it can be nearly impossible to tell where that humming, whining, or whirring noise is coming from. A common issue that many drivers run into is a failing wheel bearing, which can present in a variety of ways. While many potential issues can cause an unusual noise while you drive, a bad wheel bearing is one possibility.

As a driver, the most common way of telling a failing bearing is a grinding noise that tends to get worse the faster you go, or the noise may only present itself when you are turning.

Wheel bearingnoise when driving

The brake discs on your car are part of the rotating assembly connected to the hub and wheel bearing. When your wheel bearing has failed to the point of lateral play, the disc will no longer be aligned correctly. This means when you press the pedal, it may feel soft and take longer for your car to stop.

Frequently driving through mud or water can speed up the failure of a wheel bearing, while if you have one replaced and the new bearing is not installed in perfect alignment, this can cause premature wear.

Remember, a bad bearing will make the same noises no matter what road surface you are on. If you hear a noise that changes when you get on a more smooth or more rough road, you might be hearing tire noise.

When in doubt, bring your car to a technician. When it comes to wheel bearings, it’s better to be safe than sorry. If you aren’t sure whether the sound you are hearing is a bad wheel bearing, the technicians at Matson Point S will take a look and let you know exactly what is wrong with your car.

When the bearing fails and comes apart, it will cause play in the wheel. This can lead to severe instability when driving at high speeds and can come on suddenly if the bearing completely fails while you drive.

Unfortunately you can’t: the only solution to a worn, noisy wheel bearing is to have it replaced by a garage; bearings are not repairable.

This will depend on the car and how much parts are, and what your garage’s hourly labour rate is, but wheel bearings are not hugely time consuming to replace, and £200-£250 should get the job done.
