They usually wear out because of other engine functions, not those of the bearing itself, which makes it impossible to predict how long they'll last or when they'll fail. Under ideal conditions, they'd last indefinitely. However, they're usually made of copper and lead compounds, which are subject to a variety of weaknesses. The most important factor is lubrication. As long as there's a steady flow of clean oil, the bearings will generally keep moving along fine. If the oil's dirty, though, or if the supply is cut off, that's when the problems start.

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 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.

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.”

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.

These are all common conditions in a car's engine and are sometimes signs of other problems. There aren't many external indicators of crankshaft bearing problems, but if you suspect the oil supply might be compromised, there's a good chance there might be premature wear inside. If your crankshaft is losing oil from a faulty seal, you'll see a puddle in your parking spot; when the car's running, you'll smell oil burning as it drips on the hot manifold. Be careful, because it only gets worse from there [source: Allen].

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.

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.

Crankshaft bearings support the crankshaft (one of the components that makes the engine rotate), which sounds simple enough. However, crankshaft bearings also have to reduce friction between the rotating crankshaft and stationary engine block, and that's how they sustain most of the damage over their lifespan [source: Kaufman].

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.

Though the bearings don't have a recommended replacement interval, replacing them is a standard part of an engine rebuild service. Putting dirty, scratched, corroded bearings back in a newly rebuilt engine makes little sense; the old parts will quickly damage the fresh parts. If you do end up with new crankshaft bearings, they might last a little longer this time around. Some original equipment manufacturers (the companies that supply car manufacturers with the parts they need) are switching to aluminum bearings instead of the traditional copper/lead type. Aluminum is less expensive and more durable, and it has better temperature tolerance [source: AA1Car].

The typical sounds of worn-out wheel bearings are squealing and/or growling. The sound intensifies as vehicle speed increases. Try to pinpoint the location of the noise because it will identify the location of the worn-out bearings.

So what happens when your crankshaft bearings finally yield? If your mechanic tells you there's "catastrophic engine failure," he's not embellishing for dramatic effect -- it's the actual term used. When crankshaft bearings fail, the increase in heat, pressure and metal-to-metal contact can cause distortion of the crankshaft and connecting rods, which in turn will cause the engine to seize. It'll be necessary to completely disassemble and reassemble your engine (if you decide to keep the car, that is).

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.

In some cases, car maintenance is straightforward and simple. Just change the oil and belts according to the manufacturer's recommendations, listen for weird noises and keep an eye on the instrument panel for warning lights. A lot of parts give us ample warning before they give up the good fight. Unfortunately, we enjoy no such insight when it comes to crankshaft bearings.

In this story, we’ll tell you quick facts to know, such as what causes a bad wheel bearing, how long you can drive on one, and the estimated replacement cost of a wheel bearing as you maintain your vehicle.

“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.”

The most easily identifiable and common symptom of bad wheel bearings is audible. But it can be confusing. For example, the source of a humming noise can be linked to other issues, such as tires and the CV joint.

Your vehicle will signal that it’s time to replace a failed wheel bearing. For example, if you hear unusual sounds like humming or clicking, then your bearing might be bad. Watch out and listen for these signs and symptoms:

5 types of failed crankshaft bearings

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.

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.

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.

The anti-lock warning light may illuminate if the ring, tire, and wheel wobble, the wheel’s speed sensor is no longer operating properly, and the ABS may operate sporadically or not at all. See a professional for repair.

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.

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

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.

If there is excessive play in the steering, meaning the steering seems less responsive or less precise than normal, worn bearings could be causing the problem. Also, this could be a sign the vehicle needs a wheel alignment. If you have any of the signs listed above, visit a dealer service or auto repair shop.

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.
