i took my car to Sears two weeks ago to have the tires rotated and balanced. drove it home and everything seemed fine for like 3 days. then i began to notice an intermittent squealing noise coming from my left front wheel. it sounds very similar to the brake squeal you get when your pads are shot, but this sound actually goes away when i press the brake pedal (my brakes are just fine anyway). it happens at all speeds, from parking lot crawl to 80 mph on the interstate. and it only happens maybe every other day or so. it's driving me crazy!!

anyone have any ideas what could've happened during the rotation/balance that would give this problem?

i greatly appreciate any help.
