turboz

ok here is my problem. i heard this noise when ever the car would warm up and i was driving. it sounded like the rotor was warped and it was hitting the pads. so i changed them. same noise. the noise has gotten louder.

here is what i ahve noticed:

1. it is only at a certain point in the rotation of the wheel
2. only after you drive the car for a few minutes
3. always at teh same speed of the tire
4. sometimes goes away when turning
5. no noise when cold
6. no vibration
7. no pedal pulsation
8. beaing have no play(at least not taht i can tell)
9. cv joint has some play in and out by the tranny
10. the noise does not change with pedal modulation(sopunds the same no matter how much pressure you put on the pedal)

any ideas guys. i have tried everything i can think of. the only other thing i can think of is the hub or the wheel bearing as teh car does not make the noise when tire is spun off the ground.
thanks in advance
