I drive a '99 Chevy Blazer. This morning I lost control of my blazer and laid it on its side in the snowbank on the other side of the road. It was banged up but drivable, with some body damage to the passenger side from the tree I hit and the snowbank. On the way home, I started hearing this awful noise coming from the front end, and through searching the web I've identified it as wheel bearings. Could the damage have been caused by my accident, or is this a wear-and-tear thing?
