I've noticed this, but I can't figure out what it is. I can keep my head slightly out the window and tell its coming from the front. Whenever I am driving (mostly noticeable at 30ish because its quiet), and the front wheels hit a small bump the front sounds like clanking almost?? I cant' figure out what it is. I thought it was my tires or something, but I don't think it is them anymore. Is this something caused by that 'undercarraige' thing?
