High pitch noise

[nickm]

I had a noise like that I found today. It was the master cylinder leaking vacuum between the MC and booster.

Front wheel bearings, jack it up and try to wiggle the front wheels top to bottom, there should be no play in it. They will sometimes squeel as they are going out.

I had a similar noise on my truck, haunted me for a couple of years. Ended up being a bearing on a pulley to adjust the belt for the old add on AC compressor. I only heard the noise after driving over 40 miles or so, enough for it to heat up.

Is it an automatic trans? Perhaps it's the pump or torque converter going bad.

I currently have a similar noise. I think it may be the belt. the noise only appears when i'm moving but if i push the clutch in the noise stops. I think that it could be my alternator belt because the volt meter is all over the place.

When you push the clutch in, are you letting the engine go down to an idle? Or keeping it at the same rpm?

BroncoBrandon, Try lifting the clutch pedal with your foot while it is making the noise. Or just slight pressure on the pedal. If your noise goes away or changes it could be the throw out bearing. Had similar problem with a new clutch kit in an Accord.
