Anybody else out there have this problem. I only notice the squeak when i'm going about 50 mph or faster. It's definitely a vibration squeak coming from somewhere in the cabin, near the front i think. It's a very high pitch squeak/chirp and sounds like metal on metal or metal on glass. Thanks in advance for your input, it's driving me crazy!!!

 

I have the same problem with my '04 ES. Does it happen at lower speeds at all and only when the car is moving? Mine is going in next wednesday to get looked at. I'll let you know what it is....might be the same problem. I think it is coming from the joint or the brakes. It is a very annoying high pitch metalic soud. Sometimes mine has a hum sound with it which makes me think it could be a bad bearing.
