A roaring sound began in the front left hub bearing assembly on my 2006 Chevrolet Silverado Z-71 on 25 October, 2009. On the following day, the noise became a horrible grinding sound, and the front left wheel began wobbling badly. I had to have the vehicle towed to atwood Chevrolet in vicksburg, ms where I live. I was informed that the left front hub bearing assembly was shot, and had to be replaced. Approximately 18 months before, the right front hub-bearing assembly had to be replaced on this same vehicle. The Chevrolet dealership (atwood Chevrolet) replaced the part on 27 October, 2009. I was informed by the service manager that this was occurring at a constant rate on this vehicle. When I talked to the GM representative on 28 October, I was told that 'because of the environment in which I live here in Mississippi", this is expected.
