Some may say that you can drive for up to a thousand miles with a failed wheel bearing—but the thing is, this is an arbitrary claim. There’s really no telling how long you can safely drive your vehicle in this state. It would depend on the severity of the damage to your wheel bearing, present road conditions, and other factors. So, it’s best not to push your luck.

Can your car still run with a faulty bearing? The technical answer might be yes; some wheel bearings might continue to operate normally despite the vehicle being driven with one or more noisy bearings for a very long time. The problem is that since the noise begins gradually and slowly gets worse, you might not even notice the noise if your vehicle is noisy in other ways.

A faulty wheel bearing can cause your vehicle to pull to one side during braking. This symptom can also be related to faulty brake components.

The burning smell would be hot brakes, which you should really only smell if you’re in the vicinity of a race track. On a street car it means the brakes are being overworked, in your case because the brakes are rubbing on the rotor while you’re driving.

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.

Pro Tip: If a noise happens after the tires are rotated on a front wheel drive vehicle, it may be due to the wear pattern on the tires, so be aware of that, too.

This paragraph doesn’t make sense: Older rear wheel drive vehicles had cone type wheel bearings on the front wheels that could be removed, inspected, and packed with grease, and reinstalled with new seals. Some rear wheel drive vehicles have wheel bearings of this type on the rear. In other words, if a vehicle has cone-type bearings that can be removed, inspected, and repacked, it will always be on the NON-driving wheels – the ones that don’t propel the vehicle.

Wheel bearings are in a hostile environment and are working very hard, but wheel bearings are very tough – they’re designed for the work they do. But product variability is a real thing, and again, some bearings fail while others never do.

Since the wheel bearings keep the wheel and hub assembly spinning on an axis, if the wheel bearing is compromised to the point that it can no longer maintain that axis, driving with a faulty bearing can be extremely dangerous—especially at high speeds. Think about a wheel that starts wobbling because the bearing decided to completely come apart while you’re in freeway traffic. This can happen without warning if you’ve become accustomed to the bearing’s noise as it continues to warn you by getting louder.

I replaced the calipers today, it took a full week to get the part from RockAuto–I ordered Raybesto’s “Opti-Cal” line, it’s a brand new part rather than remanufactured (I chose it because I’ve had good results with Raybestos Advanced Tech brake pads.)

In the event that this happens under weather conditions that make the road slippery, immediately maneuver your vehicle to the nearest safe spot off the road.

It seems to me that if a caliper is sticking and not fully releasing that a pull would be more likely when the brakes were not being applied. Braking would even out the braking and tend to eliminate or reduce a pull.

While driving on the highway, the steering wheel started wobbling, it seems more pronounced at higher speeds. So, I pulled over to take a look at the front wheels, maybe it’s a rock stuck in the treads (but usually stuck rocks make a clicking sound)----there are no rock pebbles. There is a burning smell, almost like burning rubber coming from the wheel well but the tires look fine, no signs of rubbing. I looked at the inner part of the tires to see if it’s rubbing against something, some suspension component perhaps: nope, looks all good. I reckon if there’s rubbing I would probably feel and hear it inside the car. The burning smell seems to be coming from the passenger front wheel well.

A faulty wheel hub and bearing assembly can also cause a vibration felt in the steering wheel. Often, the sensation will change with vehicle speed or while the vehicle is cornering.

Since I’ve had a faulty tires that caused steering wheel wobbles before, I considered that it could be the tires, but these tires are nearly brand new… the tires don’t quite explain the other symptoms.

Wheelbearingreplacement cost

Wheel bearing failure is a potentially dangerous situation at any time, so have your vehicle towed to the nearest mechanic and have your faulty wheel bearings replaced right away. Vehicle safety should always come first.

It’s worth noting that tire noise will usually change depending on the road surface. Wheel bearing noise, on the other hand, is consistent regardless of road surface and acceleration.

Modern vehicles have sealed wheel bearings that cannot be disassembled without destroying the wheel bearing assembly in the process, and on vehicles with bearings like those, you only know a bearing is bad when it begins to make noise. That’s the earliest indication of a bad wheel bearing, and front wheel bearings (both on front wheel drive as well as rear wheel drive vehicles) are the most prone to fail on modern vehicles.

Front wheelbearingnoisesymptoms

There are different kinds of wheel bearings depending on the year model and the design of the vehicle. Older rear wheel drive vehicles had cone type wheel bearings on the front wheels that could be removed, inspected, and packed with grease, and reinstalled with new seals. Some front-wheel drive vehicles have wheel bearings of this type on the rear. In other words, if a vehicle has cone-type bearings that can be removed, inspected, and repacked, it will always be on the NON-driving wheels – the ones that don’t propel the vehicle. Trailer wheels often have bearings of this type.

One other reason I suspect the wheel bearings is because: If I drive the car after it has been parked for a day, the symptoms don’t appear until after a some 10 minutes of driving…

Thanks for the tip, I inspected the rotors with my fingers and it felt smooth just like the other side. I think the rotors and pads are fine. If not, well it’s another fun project.

It’s this abnormal sound that’s the most obvious sign something is wrong with your wheel bearings. Of course, because other issues, such as cupped tires, can mimic a bad wheel bearing, you’ll want to diagnose the sound properly.

If your wheel bearing goes out while you’re on the road, it’s not advisable to keep driving. However, if there’s absolutely no alternative, make sure to maintain a slow and steady pace—do not accelerate or turn suddenly.

I’m not recommended this, but if you decide to replace the rotors for some reason, be sure to clean them thoroughly with hot water/soap before installing. They are coated with an anti-rust chemical, and forgetting to clean it off is the source of quite a few problems reported here.

Lift 1 tire off ground with jack. Put on parking brake. Idle motor in drive and listen to right side, than left. If ur lucky only 1 wheel will rumble.

Mechanics will find a safe, empty, smooth paved road, then listen carefully to the noise while swerving gently from side to side – typically when you swerve to the right, you’re increasing the load on the left side bearings, and vice versa. And again, while this is a good practice, it’s easy to be fooled into replacing the wrong bearing, even using this method – that’s why some tire shops replace bearings in pairs. If you use this method and believe the noise is tire related, you can move the front tires to the rear and see if the noise changes.

How long will a wheelbearinglast after it starts making noise

A worn-out wheel bearing may also make a high-pitched squealing sound while you’re driving. If you are able to observe these symptoms, have your vehicle checked right away. Even if your wheel bearings are not the culprit—there’s definitely something wrong with your vehicle.

Sounds to me like you have a dragging brake caliper combined with an uneven rotor. If I’m right, then your impression is correct - something quite literally is “holding it back and letting it go.”

By now, you may have an idea of how important wheel bearings are. Thankfully, there are signs that can indicate that your wheel bearings are going bad.

Just took this off my new to me accord. Seller said ball joint was bad. I moved car 10 ft in his driveway and said wheel bearing is bad too.

Bad hub bearing symptomsreddit

The older style cone shaped bearings have a series of tapered rollers in a cage with a window for each roller to keep them evenly spaced while they ride between inner and outer races. But most modern sealed bearings have steel balls with inside and outside races.

How to tell which wheelbearingisbadin the front

Wheel bearings support the weight of the vehicle and allow the wheel/tire assembly to rotate when you’re traveling down the road. All four of your car’s wheels have wheel bearings and they are designed to last the life of the vehicle. In fact, many vehicles will travel hundreds of thousands of miles/kilometers and never need a wheel bearing replacement, but others may need one or more wheel bearings replaced over their lifetime.

One tricky thing about wheel bearing noise is that a bad tire can make almost exactly the same noise as a bad bearing; you don’t want to replace a wheel bearing for a noise concern when all you need is a new tire.

Any time ever I’ve experienced a sticking caliper it was immediately or shortly following brake work (requiring retracting the caliper pistons). CSA

Badrear wheelbearing symptoms

The wheel bearing on a wheel usually consists of a pair bearing assemblies running side by side on the shaft or spindle – this keeps the spindle running straight, while a single row of balls or rollers might allow the wheel to wobble. Exceptions would be the non-tapered roller bearings on rear wheel drive vehicles, which will have only one bearing assembly at the wheel end of the axle, but the inboard end of the axle on those units is splined to the differential assembly, which is spinning in its own set of tapered roller bearings.

Your steering wheel wobbling? That’s intermittent pulling to one side. By the time the high side of the rotor rolls around again, you’ve reacted to the steering wheel wobble and pulled the car back to straight. If you were only a little bit less competent a driver you’d have your diagnosis by now.

Jul 6, 2023 — The average cost of replacing a single wheel bearing is about $350, which means replacing all four wheel bearings will amount to $1,400.

How to tell which wheelbearingisbadwhile driving

I hadn’t planned on gravity bleeding all 4 sides but I discovered that it had been leaking brake fluid from the last time I tried to diagnosis the problem. This was my first time bleeding brakes and I did it using the gravity method. It worked out better than I expected. It was fairly quick too, about 10 minutes per side of dripping. I think I replaced a lot more brake fluid than I needed to but I wasn’t concerned.

You might have seen a vehicle pulling trailer that has had the bearings neglected to the point that the wheel gets hot enough to set the tire on fire – it can happen on your vehicle in extreme cases, but it’s rare.

You were all right, it was the calipers. In your experience, you knew it was the calipers. My reasoning led me to wheel bearings but I’m an amateur DIY’er.

Over the next couple of days, I observe that the car kind of “lurches” while creeping at very slow speeds. It also feels like there’s a kind of drag and release against the car… like something is holding it back and letting it go. It’s subtle but I can feel it at slow speeds.

Also, by replacing a bad bearing early on, you can also save yourself a lot of money by avoiding possible major repairs.

Wheelbearingnoise quick fix

Once again, there are other issues besides a bad wheel bearing that can cause steering wheel vibrations. A thorough diagnosis is needed to verify the cause of the concern.

If you have an IR thermometer, compare the difference in temperature between the passenger side front wheel and the driver side front wheel after a 5-10 minute drive at highway speeds. If you don’t, very carefully touch the wheel with your finger near the lugnuts to compare - but be warned, it might hurt if what I think is wrong is actually wrong.

However, there is one thing that prevents me from being absolutely certain and that is my reasoning that bad wheel bearings on one side that causes the car to lurch and drag would also cause it to pull to one side… this is not happening, it’s not pulling to one side…

It might be a small pull…but maybe not. Depends on how sticky the caliper is but the symptoms you just posted scream “brake caliper dragging”

I have personally seen a Crown Victoria that was making a noise I would have sworn was coming from the left rear axle bearing, but after removing and inspecting that bearing (which is difficult on a rear wheel drive vehicle), I discovered that the noise was actually originating from the left front tire. And I had nearly 40 years of automotive experience at the time.

Remember, the wheel bearing not only allows the wheel/tire assembly to rotate along with the hub the wheel is bolted to, the bearing also carries the weight of the vehicle and maintains the spinning wheel’s axis by keeping it in a straight line. A failed wheel bearing won’t usually allow the wheel to come off completely unless the bearing has become so hot that the axle or spindle is glowing red. Not only can this cause a fire in the wheel well area, the wheel and hub can separate from the vehicle and… well, finish the thought. Granted, this is a very extreme case of a wheel bearing failure, but wheel bearings that have lost their grease can get extremely hot.

concur w/the above ideas, more likely some kind of brake problem. My own diy’er experience w/bad wheel bearings is that heat or steering wheel wobbling aren’t the symptoms you first notice. What you notice first is a sound, a sort of growling sound, that gets louder the faster you go. It sounds sort of like when you drive over a road with a rough-textured surface. Often the wheel bearing sound gets worse when turning too, when turning in the other direction from the side the growling is coming from.

In cases like that, or when you just decide to keep driving until the failure is complete, the bearing itself will decide for you when it must be changed, and it can do so in very unpleasant ways and never at a good time. In other words, there are instances, when left unattended to, a faulty wheel bearing can create hazardous conditions, such as the following:

A bad wheel bearing can cause the brake rotor to wobble, which shoves the caliper piston back into its bore so that when you apply the brakes, you have unexpected pedal travel as a result – making it harder to stop or causing the vehicle to pull unexpectedly to one side – never a good thing in traffic.

Another tricky element of wheel bearing noise is the need to pinpoint which wheel bearing is making the noise. Sometimes even professional mechanics will struggle with this, and there are special listening devices shops use to pinpoint which bearing is making the noise. Some tire shops will replace both front bearings if there is a bearing noise coming from the front of the vehicle; not a bad practice, actually.

If the seal that is part of the bearing fails, moisture and dirt can enter the bearing’s grease, compromising the grease’s ability to keep the load bearing elements (balls and races) lubricated. But there are times when a bearing destroys itself even though the grease is not compromised. Tiny particles of metal can begin to flake off of the races, and when this happens, those particles mix with the grease so that it becomes a grinding compound of sorts, creating a “snowball” effect whereby more metal flakes off and enters the grease charge and the bearing gets noisier with time.

Is your ABS light on, and you do not know what is causing it? A faulty wheel bearing can be a possibility. On some vehicles, the ABS sensor or encoder ring is integrated into the wheel hub and bearing assembly. As such, a failure of the wheel bearing can trigger the ABS light.

Keep in mind that might be a sticking caliper or a failing brake hose at that corner. Internal failure can act like a check valve and not let the caliper release. It’s a 10 year old car, FWIW, I had the first brake hose failure on my truck at 7 years.

Thank for pointing out that typo. The paragraph was supposed to read: Some front-wheel drive vehicles have wheel bearings of this type on the rear. We have updated the article.

When you’re driving with the music cranked up, you may not notice the different sounds that your vehicle makes. But the moment you turn the radio off and notice a growling, humming, or rumbling noise coming from your wheel bearing, you’ll know there’s a problem.

I removed the calipers to reinstall and lube the guide pins, it was difficult to remove which is consistent with stuck calipers. Then I pumped the brake pedals to push the caliper piston out, and once out it was IMPOSSIBLE to push it back in even with a lot of effort and that caliper piston push-in tool.
