Wheel Cover/hubcaps problems of the 2000 Chevrolet Blazer

Had front passenger side wheel hub (wheel bearing) assembly replaced in October 2004. In March 2005 same wheel bearing failed which needed replaced again. Now on the driver side the wheel bearing is making noise. I looked into this and alot of people have had the same problem with these vehicles and wheel bearings. This is very unsafe as the wheel bearing holds on the front wheel thus could cause wheel to fall off while driving.
