this past week i've noticed an annoying sound similar to when my last wheel bearing needed to be replaced. i'm guessing this time it's the driver's side rear wheel bearing. i'm not positive, but i'm just going with experience. does anyone know how long i can drive on this before it needs to be replaced? i'm planning on doing it this weekend. will it be ok to drive back and forth to school for the remainder of the week? also, are there any other problems that can result in a similar sound? it sounds kind of like i have huge truck tires. thanks for any help!

a worn tire can also make a similar sound.
