    I have an 06 2.7L 4cyl Tacoma Base 6 Lug 4x4 that has a slight chirping sound both at idle and while running (frequency of chirping matches engine speed). I don't have an automotive stethescope so I can't isolate where it's coming from, but when I apply pressure to the clutch (just enough travel to start feeling pressure) it goes away. I'm thinking either a bearing somewhere in the clutch...but also considering that it may be a pulley bearing. I replaced the serpentine belt about 5k miles ago and I'm considering getting a new belt tensioner, but I don't know applying slight pressure to the clutch would cause the noise to cease. Any ideas on where to start looking?

    THROWOUT BEARING. It is a sealed bearing and sounds like it is getting dry, once that happens the friction increases and failure is certain.
