I'm hearing some squealing when I'm driving, much more evident in a parking garage as oppose to open road. I am assuning it is the wheel bearing? Not sure which wheel but is it usually just the front wheels? I looked at Bay 13 and they had a write up on replacing the wheel hub. It might be a little beyond my skills so not sure if I want to tackle it. But the question is, can it be ignored for a while or does it need to be replaced right away?
