Default High Pitched noise when cold and moving...

My 99 FRC (27k miles) has been making a high pitched squeak or squeal noise when the car is cold and only when in gear and moving, usually at low rpm and high gear for a while now... the noise goes away once the car is warm, about 5 minutes. I just replaced the serpentine belt and the noise did not change... No noise if you rev the engine with the clutch in or in neutral...??? Only when in gear and moving... Any ideas??? I am driving from Chicago to Phoenix starting this Friday and am a little concerned about this developing into something on the way...

I've read something similar being caused by rust in the rear axle/hub area. Can you narrow down where the sound is coming from?

Could it be the Serpentine belt?

Did you check the air pump?

It could be the tensioner or water pump as well...

Why would the noise occur only when moving (clutch & trans engaged)? If i just rev the engine cold I get no noise... which tells me it isn't the water pump or other belt-related item...???

The serpentine was just replaced as stated in the original post.

When you hear the squeal, tap the brakes and see if the noise goes away. It may just be the pads coming into contact with the rotors.

It is not the brakes, the noise sounds almost like a bearing from inside the alternator or something... and once it gets warm - no noise... This is what is so puzzling... it isn't the wheel bearings because the noise isn't constant with the speed of the car... it starts or gets louder when I hit the gas, but only if I'm moving... typically 3rd gear 25-35 mph...

I would not take that car on a long trip without fixing whatever is wrong with it... can you take it to the dealership for repairs?

I also have a strange high pitched noise when moving and also only between 1300 and 1800 rpm in gears 3-6. But mine comes from the back of the car. :skep: I have no clue what it could be!
I also have 27k miles!!! :rolleyes:
