When I let out the clutch I hear a noise like a deep squeak but only when in gear. No noise in neutral. Thinking it might be the throw out bearing? Looking for ideas and or things to try.
Thanks!

 

Is it only while engaging the clutch? or is it noisy the entire time the clutch is out? I'd say your diagnoses is fairly spot on.

 

The throw out bearing is always spinning as long as the car is on. Clutch disengaged, engaged, whatever. It has more load on it when you push the pedal down, though.

If its a squeaking noise, it could be a master cylinder pushrod squeak or a slave cylinder pushrod squeak.

 

I just took the car to Discount Tires and had the air pressure set to 36 lbs. hot. I know this may seem odd but no more noise from the clutch pedal. Go figure...
