I'm trying to diagnose a noise that sounds like its coming from the clutch pedal. Since the car is new to me, I pulled the pedal assembly, cleaned it, and reinstalled new bronze bushings. It seemed fine at first with no noise but after a little while, the creaking sound came back and now, most times when I drive the car, there is no noise initially but after several gear changes, the noise comes back. Its not as bad as before and the operation of the pedal is smooth. Any ideas of things to check?
