Hi,
I'm on vacation right now with my 300D and when I was driving next to a road divider (on my left) with the window down, I heard a squeak squeak squeak noise coming from what I think is the front. What could this be? Wheel bearings? (they were replaced 50K miles ago, the car has about 160K on it now) I can only hear the noise with the window down and with no stereo on. Once the windows go up, it's hard to hear. Thanks for the advice. This board is wonderful. So wonderful that I have had all my questions answered just by reading and following everyone else's posts. I need to take this car on a thousand mile trip in three weeks. Should I address this problem now? or should I wait until it gets worse? Could the squeaking have to do with brakes? The rotors haven't been replaced in a while. Oh, and I hear the noise while coasting. It is probably there while accelerating but I can't hear it over the engine.
