Can You Check Wheel Bearings While Driving?

It is a common question among drivers to wonder whether they can check wheel bearings while driving. In this article, we will explore the possibilities and limitations of diagnosing wheel bearing issues while operating a vehicle. We will also provide insights into the signs to look out for as well as why it might be necessary to seek professional assistance for a thorough evaluation.

Signs of Wheel Bearing Issues While Driving

1. Listen for Unusual Noises

Humming or Growling: A common sign of failing wheel bearings is a humming or growling noise that increases with speed. If you hear this, it may indicate that the bearings are worn.

2. Vibration

Steering Wheel Vibration: If you feel unusual vibrations in the steering wheel while driving, it may suggest that the wheel bearings are not functioning properly.

3. Handling and Steering

Pulling to One Side: If the vehicle pulls to one side while driving straight, it could indicate a problem with the wheel bearings or other suspension components.

Checking Wheel Bearings Thoroughly

While you can perform some checks while driving, it is essential to take your vehicle to a professional for a comprehensive evaluation if you notice any signs of potential bearing issues. Regular maintenance can help prevent wheel bearing failure and ensure safe driving. Here are some steps to perform a more thorough check while the vehicle is stationary:

Check for Play

1. Jacking Up the Vehicle:

Jacking up the vehicle and securing it on jack stands.

2. Inspecting the Wheel Bearings:

Grabbing the wheel at the 12'oclock and 6'oclock positions and pushing and pulling. If there is noticeable movement, the bearings may be worn.

Inspect for Heat

1. Wheel Temperature:

After a drive, carefully touch the wheel hubs to check for excessive heat. A hot wheel may indicate bearing failure.

These steps provide a more detailed evaluation of your wheel bearings, ensuring that any issues are identified and addressed promptly.

Modern Cars and Feedback

Modern cars often come equipped with advanced features that can mask the feedback that drivers would otherwise receive from a failing wheel bearing. Here are a few points to consider:

If You Drive a Modern Car

Without the appropriate sensory feedback, you are unlikely to notice a failing wheel bearing unless the noise is very loud due to lubricant loss. It is essential to have a professional inspection if you suspect any issues.

Driving an Older Car Without Steering Assistance

Yes, if a wheel bearing is just slightly out of adjustment or failing, you can feel it via the steering wheel because of the absence of power steering. However, it is always safer to have a professional mechanic inspect the wheel bearings for you.

Case studies from experienced mechanics highlight the importance of professional inspections. For example, a driver might report that one front wheel needs adjustment, but only minimal adjustment is actually needed. In contrast, another driver might report a potential issue, but the damage is so extensive that a front wheel is a few miles away from falling off.

The Impact of Modern Driver 'Aids'

The reliance on driver aids in modern cars can sometimes make it more challenging for drivers to notice important feedback. Here are a few points to consider:

Visual and Sensory Feedback

Modern cars may remove important visual and sensory feedback, making it harder for drivers to identify potential issues. The absence of feedback can lead to dangerous situations, such as a wheel falling off during driving.

The Role of Driver Education

The increase in driver ignorance can be traced to the over-reliance on driver aids in modern cars. It is crucial for drivers to familiarize themselves with the signs of wheel bearing issues and the importance of regular professional inspections.

In conclusion, while you can perform some checks while driving, it is essential to seek professional assistance for a comprehensive evaluation. Regular maintenance can help prevent wheel bearing failure and ensure safe driving, especially in modern vehicles.
