The CV axle is located under the car, with wheel bearings connecting it to the wheels. If the bearings begin to fail, it could lead to a bigger problem, or even a dangerous situation.

When the bearing first starts to have trouble, it may vibrate the car softly. As the car is driven down the road, this vibration can be felt coming up from the floor of the car. Although it starts out as a soft vibration, it will gradually worsen over time.

As the bearing damage increases, the car will begin to shake hard enough to feel it on the steering wheel. But it does depend on which bearing is going out and what the damage is, as to how the vibration presents itself.

Another telltale sign of bad bearings is loud noise. There may be grinding sounds or screeching sounds. Again, as with the vibrations, these sounds will tend to start out small and grow more noticeable as the problem continues.

If the failing bearing is left unrepaired, the entire wheel assembly could come off the car, shattering the casing. In some cases the car could just suddenly lock up. A very serious accident could occur in such a scenario. So, repair for axle bearings should be timely, in order to avoid serious damage to the car and injury or death to the people in and around the car at the time of bearing failure.
