My car is making a humming noise that gets louder at higher speeds. What should I do?

Answer:

Our first thought is this: Have the car’s tires or wheels bearings been checked recently? Most of the time a humming noise while driving is caused by tires chopping or cupping. If the noise becomes louder at higher speeds, the wheel bearings could be the cause.

The best way confirm the cause of the noise is to have a certified technician put the car on a lift and spin the wheels. This will pin down the source and then highlight the appropriate repair. Warning – do not drive the car any longer if the noise is really bad. The problem could cause over-heated bearings, bearing hubs and possibly tire damage. All of this can result in other costly problems.
