Why does my wheel hub make noise when driving?
However, wheel bearing noise stays consistent despite the road surface. Bad wheel hub noise typically increases when you accelerate, change direction, or steer the wheel in a different direction. However, this noise could be due to other vehicle problems, such as cupped tires which produce the same sound as a bad wheel hub.
Can you drive with a bad hub assembly?
Q: Is it safe to drive with a bad wheel bearing? 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.

When the vehicle is on a hydraulic lift or on jack stands, and the tire / wheel combo is tightly attached to the wheel hub assembly, but wiggles from left to right or up and down when pulled, this is an indication of a broken wheel hub assembly and should be replaced immediately. Once again, broken wheel hub assemblies should be replaced in pairs on the same axle.
How to tell if wheel hub is bad?
Another indication of a damaged wheel hub assembly is when the steering wheel vibrates at lower speeds and progressively gets worse as the car accelerates. A damaged wheel hub assembly can also cause the steering wheel to feel loose when you're driving down the road, making turns or negotiating dips in the road. The reason for this is commonly due to a worn out wheel bearing inside the hub assembly. If you notice this symptom, it's recommended to contact a certified mechanic as soon as possible so they can road test your vehicle. This is often the best way to properly diagnose what is actually causing the vibration in the steering wheel, and can save you a lot of time and money on replacing the wheel hub assembly.

Today's modern cars, and those manufactured after 1997 are equipped with a single bearing and hub assembly that is attached to each wheel and tire on a vehicle . The wheel hub assembly includes wheel studs that attach the wheels of the vehicle to the car and is mounted to the steering and suspension system on the front end and the rear axle on the rear end. In theory, this single wheel hub assembly should last the lifespan of the vehicle, however, like any other mechanical device, it is subject to wear and tear and can break or wear out prematurely.
What causes a wheel hub to break?
When that happens, it’s easy to wonder what went wrong. There are three common causes of bearing failure: impacts, contamination, or improper alignment.
What is the job of a wheel hub?
The wheel hub’s job is to connect the axle and wheel and to allow the wheel to spin smoothly. Most of the time a vehicle is traveling in a straight line, which puts only minimal stress on the wheel bearing. If your vehicle is out of alignment and pulling, you have to constantly turn slightly to keep the car going straight. Then the bearing is under the added stress of a slight turn all the time. This causes the bearing to wear faster.
How to tell if a wheel bearing is failing?
Another way to determine if the wheel bearing is failing is to measure the runout of the hub. Runout is a measurement of the amount of play in the wheel bearing. You need a dial gauge to precisely measure runout. The rule of thumb is that if the hub’s runout exceeds .004″, the bearing has failed.
What happens if your wheel bearing breaks?
The bearing either breaks or becomes weaker, leading to eventual failure. Is your car driving differently after hitting a pothole or something else? Your wheel hub assembly may have taken a beating and need inspection.
How to test for bearing failure?
Gently rock the wheel to see if there’s any noticeable play. (Note: In the early stages of bearing failure, this test may fail to detect the failure.)
Do wheel hubs corrode?
Like all the components under the car, wheel hubs are continually exposed to water, dirt, dust, and other contaminants. They will corrode over time. Cars that live in cold climates are subject to salt and magnesium chloride. If you drive in the rain, some water may splash on the components in the undercarriage. But your wheel hubs get bathed in water. Wheel hubs are very exposed to the elements, so corrosion may cause problems sooner than it would for other components under the car.

This symptom can also be related to faulty brake components. Do your homework (or have a mechanic do it for you) to know for sure.
Why does my wheel bearing make a noise?
Wheel bearing noise coincides with the rotation of the tires. The sound typically increases with vehicle speed as well. In some instances, the noise may also change when you turn the steering wheel in one direction or the other.
How long can you drive with a wheel bearing out?
If your wheel bearing goes out while you’re on the road, it’s not advisable to keep driving.

How many hubs are there in a car?
Most vehicles have four individual wheel hubs, each of which acts as a mounting point for one of the wheel/tire assemblies. The hub itself is a flange with protruding mounting fasteners, called lug studs, that the wheel mounts to.
What is a front locking hub?
The design locks the hub (either automatically or manually) to the axle shaft, so that rotational force can be routed from the front differential to the front wheels.
Why is a wheel hub important?
A wheel hub is a part you absolutely should not skimp on because it plays an important part in ensuring that your wheels function properly. A low-quality wheel hub assembly is likely to bring on a whole lot of problems shortly after installation because it’s not designed to hold up well over time.
How much torque does an impact wrench produce?
Modern impact wrenches are very powerful. Many can produce 500 to 1000 ft. lbs. of torque, which is more than most automotive engines. But they do not tighten to a precise amount of torque. A torque wrench is specifically designed to help you torque a fastener to a precise measurement, which is necessary when installing a wheel hub assembly. The amount of torque you use makes a big difference in your wheel hub’s performance. For example, an over-torqued assembly takes on excessive load. An under-torqued assembly can reduce the bearing’s lifespan or even cause the bearing assembly to fail.
Can a loose axle shaft damage CV joints?
