Do bearings give warning before they fail?
Bearings are a critical component in your vehicle, ensuring smooth operation of various systems, from the wheels to the engine. However, like any mechanical part, they are subject to wear and tear over time. One common question we hear at Kevin's Autos is whether bearings give any warning signs before they fail. The answer is yes—most of the time, bearings will provide noticeable symptoms before a complete failure occurs. Recognizing these signs early can save you from costly repairs and potential safety hazards.
Common Warning Signs of Failing Bearings
Bearings rarely fail without some form of warning. Here are the most common signs to watch out for:
- Unusual Noises: One of the earliest and most noticeable signs of a failing bearing is noise. You might hear a grinding, humming, or growling sound coming from the wheels or engine area. The noise often gets louder as you accelerate or turn.
- Vibration: A worn-out bearing can cause vibrations that you may feel through the steering wheel, floor, or even the seat. This is especially noticeable at higher speeds.
- Uneven Tire Wear: Bearings that are not functioning properly can lead to uneven tire wear. If you notice unusual patterns on your tires, it could be a sign of bearing issues.
- Wheel Play: If you suspect a bearing issue, you can check for wheel play. When the vehicle is lifted, try moving the wheel back and forth. Excessive movement could indicate a worn bearing.
- ABS Warning Light: In some cases, a failing bearing can trigger the ABS (Anti-lock Braking System) warning light on your dashboard. This happens because the bearing affects the wheel speed sensor, which is part of the ABS system.
Why You Shouldn't Ignore These Signs
Ignoring the warning signs of a failing bearing can lead to serious consequences. Bearings play a vital role in maintaining the stability and safety of your vehicle. If a bearing fails completely, it can cause the wheel to lock up or even detach from the vehicle, leading to dangerous situations on the road. Additionally, driving with a failing bearing can cause damage to other components, such as the hub, axle, or suspension system, resulting in more expensive repairs.
What to Do If You Suspect a Bearing Issue
If you notice any of the warning signs mentioned above, it’s important to address the issue promptly. Here’s what you should do:
- Inspect the Vehicle: If you have the tools and knowledge, you can perform a basic inspection to confirm the issue. However, this is not always feasible for everyone.
- Visit a Professional Mechanic: At Kevin's Autos, we have the expertise and equipment to diagnose and repair bearing issues efficiently. Our team can ensure your vehicle is safe and running smoothly again.
- Don’t Delay Repairs: Even if the symptoms seem minor, delaying repairs can lead to more significant problems and higher costs down the line.

Frequently Asked Questions
How much does it cost to fix a wheel bearing?
Front-Wheel Bearings – Traditional Cone or Roller
All in, labor and rotor, most vehicles will run around $150.00 to replace and go up depending on rotor cost. In many cases, it's cheaper to replace the rotor than it is to remove and press in a new bearing race.
Can I still drive with a bad wheel bearing?
Driving with bad wheel bearings is not recommended as it can lead to serious safety risks. Signs that wheel bearings need replacement include a humming or grinding noise, vibrations, or wobbling wheels.
How long can you go with a bad bearing?
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.

What is the average life of a wheel bearing?
approximately 85,000-100,000 miles
As mentioned previously, the average life of wheel bearings is approximately 85,000-100,000 miles. However, that lifespan can be shortened if you hit a curb, speed bump, or pothole at high speeds. Contamination from water, mud, road salt, or sand can also shorten the life of your wheel bearings.
What is an indicator of a bad bearing?
If the wheel bearing is in bad shape, we will hear a grinding sound regardless of the speed we are driving at. The noise will speed up at the same rhythm that the car does and it gets louder or quieter when cornering, depending on whether the cornering inner or outer wheel bearing is defective.
What are the first signs of bearing failure?
We focus on the warning signs that are indicative of poor bearing condition, such as squeaking and grinding noises. Indicators like excessive vibration, will increase bearing noise, the rate of fatigue, and shorten the bearing's service life.
Do bearings usually give warning before they fail?
The fundamental frequency and harmonics begin to decrease as the random ultrasonic noise is boosted. Temperatures will start to skyrocket as the bearing self-destructs. So, the short answer is yes. There are definitely warning signs of a bearing about to fail.
How do you detect early bearing failure?
1- Monitoring Bearing Condition: Machine bearings are generally monitored through vibration analysis, oil analysis and/or ultrasound techniques. In most cases vibration analysis and oil analysis are still the best ways to determine bearing health.
What are the signs of a wheel bearing going bad?
A humming, rumbling or growling noise that increases with acceleration or as the vehicle turns. A loud constant whining or grinding noise when the vehicle is in motion. Clunking noises when driving over uneven road surfaces.
