Alright so I drive a 2001 Land Rover and lately it has been making a loud sound sometimes, well I took it to the mechanic shop and the man told me it was my wheel bearing that was messed up and to fix it, it would be $700! which I really don't have right now. I am wanting to know if I continue to drive my car only to the places I need to go to, could my tire potentially fall off or something?
