What is the most common cause of bearing failure?
Bearings are critical components in your vehicle, ensuring smooth operation of various moving parts. However, when bearings fail, they can lead to significant mechanical issues and costly repairs. At Kevin's Autos, with years of experience in car maintenance and repair, we’ve seen firsthand the most common causes of bearing failure. In this article, we’ll explore the primary culprit behind bearing failure and how you can prevent it.
Understanding the Role of Bearings in Your Vehicle
Bearings are designed to reduce friction between moving parts, allowing for smooth rotation and movement. They are commonly found in wheels, engines, transmissions, and other critical systems. When functioning properly, bearings ensure efficiency and longevity of these components. However, when they fail, the consequences can range from annoying noises to complete mechanical breakdowns.
The Most Common Cause of Bearing Failure: Contamination
Contamination is the leading cause of bearing failure. This occurs when foreign particles such as dirt, dust, water, or debris infiltrate the bearing assembly. These contaminants can damage the smooth surfaces of the bearing, leading to increased friction, overheating, and eventual failure.
How Contamination Happens
Contamination can occur in several ways, including:
- Improper Sealing: If the seals around the bearing are damaged or improperly installed, they can allow contaminants to enter.
- Environmental Exposure: Driving through water, mud, or dusty conditions can introduce contaminants into the bearing assembly.
- Improper Maintenance: Using unclean tools or failing to clean the surrounding area during repairs can introduce debris into the bearings.
Preventing Bearing Failure
While contamination is a common issue, it is also preventable. Here are some tips to protect your bearings and extend their lifespan:
- Regular Inspections: Check your vehicle’s bearings and seals during routine maintenance to ensure they are in good condition.
- Proper Sealing: Ensure that seals are correctly installed and replace them if they show signs of wear or damage.
- Clean Work Environment: Always clean the area around the bearings and use clean tools during repairs or replacements.
- Avoid Harsh Conditions: Minimize driving through water, mud, or dusty environments whenever possible.
- Use Quality Parts: Invest in high-quality bearings and seals to reduce the risk of premature failure.
Conclusion
Contamination is the most common cause of bearing failure, but with proper maintenance and care, it can be avoided. At Kevin's Autos, we’re here to help you keep your vehicle running smoothly.

Frequently Asked Questions
Do bearings give warning before they fail?
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.
What is the life expectancy of a bearing?
Table I
| Operating Condition | Minimum L10 Life (Hours) |
|---|---|
| Intermittent operation during day, reliability important | 12,000 |
| Continuous 1 shift operation | 20,000 |
| Continuous 2 shift operation | 40,000 |
| Continuous 24 hour operation | 60,000 |
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.
How do you diagnose a bad bearing?
Bad Wheel Bearing: Signs and Symptoms It's Time to Replace
- Humming Noise. The most easily identifiable and common symptom of bad wheel bearings is audible.
- Squealing, Growling.
- Clicking Sound.
- Wheel Wobble.
- ABS Failure.
- Uneven Tire Wear.
- Vehicle Pulls to One Side.
- Steering Wheel Vibration.
What are bearing problems often caused by?
Lubrication is a leading cause of bearing problems. Most people understand that the balls inside a bearing should never ride directly against the bearing raceway. The tricky part is knowing how much or how little lubrication a bearing needs.
Is it OK to drive with a bad bearing?
How many miles can you drive on a bad wheel bearing? The lesser, the better. As we said before, this issue can lead to a very dangerous situation. If it's unavoidable, the most appropriate way to do so is to drive as slow as possible to minimize the friction.
Should you spray WD40 on bearings?
Spraying WD40 will remove the old grease, but it won't clean your bearings, and it won't regrase them afterwards. Filling your bearings with WD40 and skating them without regreasing will result in destroyed bearings.
What kills bearings?
Contamination & Corrosion
There are many contaminants that can cause problems with a bearing. Dirt, sand, and water are the most common ones that you run into, but chemicals and corrosives can also damage bearings.
How can bearing failure be prevented?
Proper handling and installation of bearings is essential to preventing premature failure. Ensure that bearings are stored and transported in a clean, dry, and vibration-free environment. During installation, ensure that bearings are properly aligned, and torque is applied correctly.
What are the main causes of bearing failure?
12 Reasons Why Bearings Fail
- Lubrication Failure. According to a recent study, up to 80 percent of bearing failures are caused by improper lubrication.
- Contamination.
- Improper Mounting.
- Misalignment.
- False Brinelling.
- Corrosion.
- Electrical Damage (Fluting)
- Fatigue (Spalling)
