1. Intruduction:
A wheel bearing operates in a car as part of the suspension. They have two jobs. Wheel bearings support the vehicle's weight and allow the wheel to spin with minimal function. To perform these tasks properly, a wheel bearing must be in good condition. There cannot be any leaks. Once a wheel bearing starts to leak, your wheel bearing is in trouble. This allows water and dirt to enter in and the grease to leak out. The first sign of a bad wheel bearing is the noise it will make. The noise is usually a rumbling or thumping noise.
2. Recognizing a Bad Wheel Bearing.
Once you recognize the noise as a bad wheel bearing, you may also notice some other symptoms. The alignment will be off in your car. You will notice the car pulls to the side the bad bearing is on. The noise of the rumbling may disappear with certain speeds and may change when turning as well. A bad bearing is often mistaken for a bad CV joint. A bad CV joint noise is a clicking when turning. Your tire, when the car is parked, will move about 2 to 3 inches when you wiggle it. Your tire should not move at all.
