Noise is a Major Symptom of Bad Wheel Hub Bearing

There are two important roles played by car wheel bearings.

• Wheel bearings allow the wheels to rotate with little friction.  
• Bearing support a car’s weight

These are overlooked parts and as your car gets older, it is better to keep an eye on these parts. Every vehicle is different so when it comes to repairs, safety should be your number one priority. If you cannot do it alone, always seek the assistance of a parts pro, professional mechanic or installer.

Due to abnormal tread ware, tire noise usually shows up as a whine or a thumping sound caused by ply separation. Wheel bearing noise is also similar but it is caused by dry, worn wheel bearings. Steady humming type sound is caused by wheel bearing. The cause is due to rollers or balls being damaged from lack of lubrication and are no longer smooth. To check the bearing, wiggle the tire back and forth to check and see whether there is play. The wheel bearing may have to be disassembling the wheel bearing to verify the problem.

Noise is the first sign of a bad wheel bearing.  You have to identify whether the noise is coming from the front wheel bearing or the rear wheels. While accelerating or decelerating at a steady speed the noise comes. When the car is turning if there is a noise, the hub bearing in the front wheel is bad. You must not confuse the noise with a damaged CV joint. The damages CV joint also gives a noise. A bad hub bearing gives a noise due to the lack of lubrication or because of damage .Front wheel hub bearing should be serviced every 30,000 miles.

The noise coming from the front wheel and the rear wheel is almost same. Drive the vehicle at a steady speed and if there is a noise coming often, then the hub bearing in the rear wheel is bad. This is just a brief summary of a bad hub bearing.
