Warning Signs Your Wheel Bearings Are Failing
Warning Signs Your Wheel Bearings Are Failing
Every year, more than 200,000 accidents occur due to wheel bearing failure, according to the National Highway Traffic Safety Administration (NHTSA). Don't let your vehicle become a statistic. Familiarize yourself with the common symptoms of wheel bearing failure so you can take action before it's too late.
Signs of a Failing Wheel Bearing:
- Grinding or humming noise: A grinding or humming noise that increases with speed is a classic sign of a failing wheel bearing. The noise is caused by the damaged bearing grinding against the metal components of the wheel assembly.
Table 1: Grinding or Humming Noise Levels
| Noise Level | Bearing Damage |
|---|---|
| Slight humming | Minor damage |
| Moderate grinding | Moderate damage |
| Loud screeching | Severe damage |
- Wobbling or vibration: A wobbling or vibrating steering wheel, especially at highway speeds, can indicate a failing wheel bearing. The damaged bearing allows the wheel to move excessively, causing the vehicle to shake.
Table 2: Wobbling or Vibration Severity
| Vibration Intensity | Bearing Damage |
|---|---|
| Slight shaking | Minor damage |
| Moderate vibration | Moderate damage |
| Severe wobbling | Severe damage |
- Increased rolling resistance: A failing wheel bearing can increase the rolling resistance of the affected wheel, making the vehicle feel sluggish and requiring more effort to accelerate.
Stories of Wheel Bearing Failure:
- Benefit: Recognizing the symptoms saved lives
- How to do: A family was driving on a busy highway when they heard a grinding noise coming from their front end. They pulled over and called a tow truck, which took the vehicle to a mechanic. The mechanic diagnosed a failing wheel bearing and replaced it, preventing a potentially catastrophic failure on the highway. - Benefit: Catching it early saved money
- How to do: A mechanic heard a humming noise coming from a customer's car during a routine inspection. The noise indicated a minor wheel bearing problem, which the mechanic replaced before it could cause more significant damage, saving the customer hundreds of dollars.
Effective Strategies to Prevent Wheel Bearing Failure:
- Regular maintenance: Following the manufacturer's recommended maintenance schedule is the best way to prevent wheel bearing failure. Regular inspections can identify and address potential problems before they become serious.
- Avoid potholes and rough roads: Potholes and rough roads can put excessive stress on wheel bearings, causing them to fail prematurely. If you must drive on rough roads, slow down and avoid hitting potholes directly.
- Proper tire care: Underinflated or overinflated tires can put stress on wheel bearings, leading to failure. Maintain proper tire pressure and rotate your tires regularly to ensure even wear.
Pros and Cons of Repairing Wheel Bearings:
Pros:
- Can restore vehicle performance and safety
- Can prevent costly repairs in the future
- Relatively inexpensive (typically $150-$500)
Cons:
- Can be time-consuming to repair
- May require specialized tools and equipment
- Can temporarily reduce vehicle mobility
FAQs About Wheel Bearing Failure Symptoms
- What is the average lifespan of a wheel bearing?
