Why are wheel bearings important?

Wheel bearings are essential in the operation of your vehicle. More precisely, a wheel bearing is crucial for the proper function of the hub, tire and wheel assemblies to work together. The wheel bearing allows friction-free movement and rotation of the hub assembly, and thereby provides smooth tire and wheel rotation.

What do wheel bearings attach to?

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.

Do wheel bearings affect speed?

Other tire problems that cause excess vibration often show up at high speeds. On the other hand, a failed wheel bearing can cause vibration issues at much slower speeds, only to grow worse as your vehicle picks up speed. Failing wheel bearings also often cause the affected wheel to wobble back and forth while moving.

What are the 2 types of wheel bearings?

In modern passenger cars, two types of wheel bearing are used in accordance with requirements: taper roller bearings and ball bearings. The versions of these bearings that are used vary according to application and load.

What will happen if wheel bearing fails?

Bad wheel bearings can cause the steering wheel to vibrate. The intensity increases as the vehicle speed increases and the vehicle turns to the left or right. However, the vibration could be linked to an out-of-round tire (there could be a flat spot on the tire) or is no longer balanced.

How long do wheel bearings last?

about 85,000 to 100,000 miles

Most wheel bearings last about 85,000 to 100,000 miles before they need to be replaced. Some vehicles have wheel bearings that last a lot longer, and some vehicles need them replaced fairly quickly. It all depends on the quality of your wheel bearings and your usual driving conditions.

What causes wheel bearing failure?

Frequently driving through mud, water, or road salt can cause wheel bearing malfunction. Contaminants can get past the seals and enter the bearings, which pollutes the grease and damages the bearings.

What is a wheel bearing made of?

steel

Wheel bearings are made of high-grade steel, and the inner and outer races (called the cone and cup) as well as the rollers or balls are all heat-treated to harden their outer surfaces.

What holds the wheel bearing?

The wheel bearing lies inside of the hub assembly. The hub is what holds the lug nuts that are used to secure the tires to the wheels. Hubs are made to support the weight of the vehicle, travel over all kinds of road conditions, turn corners while facilitating the wheels as they spin at many revolutions per minute.

How do wheel bearings break?

Driving conditions – driving through deep water or mud can cause your wheel bearings to fail. Water, mud or other contaminants such as dust or road salt could get past the seals and enter the bearing, polluting the grease and wearing away the bearings.

Can wheel bearing fall off?

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.

Can wheel bearing affect alignment?

Bad bearings will affect the alignment of your vehicle and the way your car handles. If your tires are wearing through quickly or unevenly, or your car seems to drift around on the road, a wheel bearing or alignment issue is to blame.

How do you check wheel bearings?

Quote from video: And give it a little shake. If there's any play or any kind of clunkiness. That's kind of one step further towards that is a bad wheel bearing.

Can wheel bearings overheat?

If a wheel bearing overheats, the hot lubricant breaks down and can cause scoring and even etching of the bearing surface. Also, water and other corrosive elements can create this condition, which lead to spalling down the road. Burned or oxidized lubricant may leave a dark coating on bearing surfaces.

What to do if wheel bearing goes out while driving?

How important is replacing a wheel bearing?

The absence of wheel bearings in good condition can ultimately lead to uneven wear on your tires and brakes, as well as other serious damage to the vehicle. It can also increase your risk of getting involved in a car accident.

Do wheel bearings affect brakes?

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).

Are wheel bearings important to replace?

A: Eventually, all wheel bearings wear out and will need to be replaced. Assuming normal service under typical driving conditions, the newer, “hub-assembly” style bearings found on most modern vehicles should last around 100,000 miles when maintained properly.

What causes wheel bearing failure?

Frequently driving through mud, water, or road salt can cause wheel bearing malfunction. Contaminants can get past the seals and enter the bearings, which pollutes the grease and damages the bearings.

Can wheel bearing be repaired?

Depending on the vehicle and its front, rear or all-wheel-drive, repairs can be quite involved. Brakes and rotor assemblies are removed first to expose the axle nut and hub assembly. The old bearings are removed and replaced with new units and then reassembled.

How do you diagnose wheel bearings?

Quote from video: So what we're going to do is we're going to grab the tire at the three and nine o'clock positions. We're going to shake it back and forth. And you can see right there you see that little play.
