OK, i know that my wheel bearing is on its way out, when it was serviced recently he asked me if i wanted it replacing. The car makes a very loud humming noise when im driving above about 30, and if i turn the steering slightly to the left it gets louder and more of a buzz.
Can you explain exactly what the wheel bearing is, what it does/where it is (i know its on the wheel!!), and what would happen if it failed altogether.
Can i keep driving with it making a noise all the time? If it fails, how will i know?
Thanks
