Just this week I started hearing some noise coming from my front wheel area. It almost sounds like a rubbing/whurring/metallic sound and it becomes louder as I accelerate. Nothing appears to be wearing, as the tire is fine and I see no other wear on the metal. While I had some noise in this front area in the past, (which I'm reading is common) it has become much more noticeable this past week. Anyone have any ideas?? Someone suggested it could be a wheel bearing issue? I probably have about 2,000 miles of decent tread left on the front tire as it stands now before I will have to invest in a new one.
