Although there is less friction when using ball bearings, they’re not made to support the same weight as roller bearings.

INSOCOAT single row deep groove ball bearings feature an electrically insulating coating on the outside surfaces of either the inner or outer bearing ring.

Wheel bearings let the wheels rotate while supporting the entire vehicle. These bearings come with rolling parts inside them that help reduce friction.

Wheel bearings connect a car’s wheels to the axles. They allow wheels to turn with minimal friction. Though wheel bearings are low-maintenance parts, they are important safety components of a vehicle’s braking, steering, and suspension systems. The one-piece hub assembly, between the drive axle and the brake disc or drums, incorporates the hub, wheel bearings, ABS (anti-lock braking system) wheel speed sensor, and mounting flange.

Worn bearings may cause a vehicle to pull to the left or right when brakes are applied. The direction the vehicle pulls signals where the worn bearings are located, on the left or right side of the vehicle. However, this can also signal brake rotor or brake caliper problems.

Lastly, fatigue or spalling can lead to fractured bearing surfaces and cause the bearing material to break off after some time.

Some vehicles also have needle bearings, which is a type of roller bearing that uses smaller needle rollers. This type is not adjustable because the clearance between the diameter of the straight roller is manufactured into the bearing itself.

Driving with bad wheel bearings impacts the safety of a vehicle, and it could cause a serious car accident. We do not advise driving on them when they fail and recommend getting them checked out as soon as possible. Bad wheel bearings can damage things like your hub, the vehicle’s constant velocity joint (CV joint), or the automatic transmission.

In some cases, you might even need to replace the entire hub because you won’t be able to get to the damaged bearing without disassembling the entire unit.

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 a tire that is no longer balanced. Another cause is damaged or worn suspension components.

However, luxury cars are more expensive to repair. Do note that if bearings go bad at one wheel, replacing the bearings at the other wheel on the same axle is unnecessary. Don’t let someone talk you into work that is not needed. Get the price estimate for wheel bearing replacement for your make and model of car.

If you hear a clicking sound that increases in frequency as the vehicle accelerates, there could be a problem with the wheel hub assembly.

Most vehicles today use sealed hub bearing assemblies that contain roller bearings. While we don’t address these, older cars used tapered roller bearings, which required servicing and preload adjusting to ensure the right amount of end play or axial clearance.

Wheel bearings are theoretically engineered to last the life of the vehicle. There is no maintenance schedule for replacing wheel bearings, and there is no constant source of lubrication. However, they can be damaged, leading to failure.

These anti-friction wheel bearings come in the form of ball, roller, and tapered roller bearings. And while each of them has distinctive features, they all perform the similar task of converting sliding friction into a rolling motion.

The tapered roller bearing is the most common type used in vehicles. It is designed to support both radial and axial loads.

The bearings are tightly packed in a grease-filled, waterproof, sealed metal ring. This housing, called a race, is located inside the hub, and each wheel has one. Wheel bearings have a Herculean responsibility: They are engineered to support the vehicle’s entire weight.

The cost would be the same as a replacement, as there’s no other way to fix a damaged wheel bearing than to replace it with a new one.

“The good news is most of the time, a vehicle will let you know way before a failure ever happens,” said Gary Hardesty, Kelley Blue Book’s in-house service and maintenance expert and an A.S.E. certified master technician. “The key is to listen to your car. Most times, a failing wheel bearing will exhibit a growling type of noise that changes with vehicle speed. The faster the car (goes), the faster the frequency of the growl.”

CarParts.com offers a wide variety of wheel bearings from the top manufacturers at different price points. You can purchase wheel bearings individually, in sets of two, or sets of four, depending on your needs.

If one tire wears out faster than the others, it could be a sign that the wheel bearings are worn. However, it also could be a sign the tire is improperly inflated (too much air pressure or not enough), the tires are improperly aligned, or the vehicle has damaged or worn suspension components.

The original equipment bearings on your vehicle are engineered for specific loads. Those bigger and wider tires look cool, as do tires with lower tread walls. But they place higher loads on the wheel bearings, possibly resulting in accelerated wear. That could present a safety issue if your wheel bearings fail.

Imagine driving on the freeway when the left front tire and wheel suddenly break off, sending your out-of-control vehicle skidding across several lanes of 65 mph traffic. This is not an exaggeration. This is reality, and can happen if you fail to notice the signs the wheel bearings are deteriorating and need immediate repairs. Your wheel bearing might be bad if you hear unusual sounds like humming, squeaking, or clicking. Some experts say a bad wheel bearing can sound like a bird chirping. Also, if your car wobbles or pulls to one side, you will want to get it checked.

Rollers on this type of bearing are secured in a cage between the inner and outer races. The tapered roller bearing is expected to move around the cage freely to allow heat expansion.

Technicians can check for wheel wobble by putting the vehicle on a lift and manually checking for wheel movement. Typically, it would be impossible to shake the wheel and tire. However, if it moves, the hub assembly needs immediate attention. The tire and wheel can literally come off the vehicle at any time, at any speed, if you don’t repair your vehicle.

The cost to replace one front-wheel hub assembly varies widely. Among the variables are the vehicle brand and model, the garage’s labor rate, and the cost of parts. The average out-the-door wheel bearing replacement cost without taxes is about $350 per wheel.

Driving with a bad wheel bearing is never a good idea. Aside from compromising your safety, you also risk damaging other parts of your vehicle, which can lead to costly repairs down the road. In extreme cases, driving with a bad wheel bearing can even cause one of your wheels to fall off while driving.

Hardesty cautions that if you think something is wrong, don’t wait to get it diagnosed: “The longer you wait, the more it will cost as other components may be damaged by a wheel bearing.”

Roller bearings have rollers between the inner and outer races to reduce friction. Compared to a ball bearing, this type has a longer contact area to support heavier loads.

Wheel bearings are generally designed to last the lifespan of your vehicle. However, driving conditions, habits, and other factors can cause them to fail like any other car part.

Wheel bearings are a crucial component because they let the wheels rotate while supporting the weight of the entire vehicle. When they become faulty, your vehicle’s wheel hubs are going to create noises and vibrations while you’re driving, which can be unnerving. They can fail catastrophically and cause your wheel to seize, which can result in a crash. Replace your faulty wheel bearings immediately with new ones from CarParts.com.
