Title: Loud ear piercing squeal
Post by: pakman84 on May 29, 2010, 02:47:52 PM

Need help-When I start my car and leave it in neutral I hear a high pitch squeel. When I depress the clutch the squeal gets extremely loud...Bad clutch,bearing???

You sure it's not a belt slipping?  You should be able to isolate it to some region of the engine.

I'd suspect the throw-out bearing.  It spins all the time, but really loads up when you push the clutch pedal in.  That'd make it squeal louder, I'll bet.

I've never had a bad one, so I can't tell you for sure.  I'd hate to guess wrong on that one...that's a lot of tearing apart to diagnose.  Might as well do a flywheel swap or clutch replacement while you're in there...

Not the belts...I tightened them up and then sprayed the belts with PB Blaster....

Mine just did the same thing - the throw out bearing is bad.
It started with a rumbly sound when the clutch was depressed.
after about 100 miles of ignoring this it now has a horrible squeal, gets much
nastier when the clutch pedal is depressed. It is either the release bearing
itself, or the bearing seized and is smoking the pressure plate fingers.
Time for a clutch kit......
