So today I changed out my clutch along with a new throw out bearing. My car was making a whining noise when the clutch pedal is out. When you push the pedal in it goes away. I was hoping that is was the throw out bearing but now it still makes the noise. Like a dummy I didn't change the pilot bearing. Could that possibly be the pilot bearing? I noticed that it particularily makes the noise when driving in 1-3rd gear. You dont notice the noise in 4-5th gear. Any help would be great.
