Front left wheel is making a high pitched squeeking noise. It comes intermittently, but usually when the car is warmed up. The squeeking is a pulsing sound also. You can hear it get louder if you brake, go over a bump, or turn the wheel. It's not ALWAYS there though, probably about %50 of the time, once the car has been driven for awhile. I couldn't figure out which wheel it was coming from, but I knew it was on the left side. When I got home last night, I pulled into the driveway, put the car in Park, and the car rocked a little (put in park on hill) and the squeeking would squeek with the rocking of the car. I then determined it was from the front LEFT wheel.

Then this morning I took the car to my mechanic to check it out. We drove behind a business complex (along a wall to hear the noise better), and it wouldn't make the noise! Finally, after a litte listening, it was there. But it's a really high pitched pulsating beep, and he couldn't hear it! Maybe I'm trying to be conacted by a different world... Anyway, I could hear it well, but he couldn't hear it, like his ears could not pick up that high of a noise.

Well I know this will not be easy to diagnose without seeing it. But any places I should look? I have braked hard a few times to try and remove glaze build-up, but it didn't really help. Should I put some glaze stuff on there anyway, just to eliminate some possibilities?
Thanks everyone!
