The Path to Wheel Bearing Failure
Warning Signs Leading Up to Failure
It’s rare for a wheel bearing to fail suddenly. More commonly, they deteriorate over time, giving several warning signs along the way. Some of these signs include:
- Grinding or roaring noise from the wheel area: This is often the first sign of a bearing starting to wear out. The noise intensifies with the vehicle’s speed or when taking a turn.
- Vibration in the steering wheel: A failing bearing can cause the steering wheel to vibrate, which can be felt especially when accelerating.
- Uneven tire wear: As the bearing loses its efficiency, it can cause uneven wear on the tires.
- Loose steering: The steering might feel loose or wander slightly from side to side, a direct consequence of a deteriorating bearing.
Knowing these signs and recognizing what happens if a wheel bearing fails can prevent more significant issues down the road.
Stages of Deterioration
The deterioration of a wheel bearing isn’t instantaneous but occurs in stages:
- Initial Wear: The bearing starts to show signs of wear, resulting in increased heat and a slight decrease in its performance. However, the symptoms might be too subtle for an average driver to notice.
- Progressive Wear: This is when the earlier mentioned symptoms, like noise and vibration, become more noticeable. There’s still time for intervention at this stage, preventing further damage.
- Advanced Wear: At this stage, the symptoms become severe. Ignoring them further can lead to the bearing getting completely damaged or even breaking apart.
- Complete Failure: This is the stage where the bearing no longer performs its function, leading to total wheel lock-up. Knowing what happens if a wheel bearing fails and reaching this stage can result in catastrophic consequences, including potential accidents.
