Default GRINDING NOISE

I have a 2003 TB LS. When i am driving i have this really bad "grinding noise" that sounds like its comin from the front end. Sort of sounds like the brakes, but it only happens when i am driving. Sounds a little worse when im in reverse. When i brake, it goes away for a bit. Its not all the time, but very frequest. Let me kno please!

We have an '04 Trailblazer with 43,000 miles on it. Made a whining/vibration sound from the front of the vehicle. Took to dealer 1/16/08 under extended warranty/$100.00 deductible. The dealer replaced left front wheel bearing assembly. Without warrantly, parts & labor $445.87. Still more problems.
