transmission/clutch whine

[bluemonkey]

I had my '93(KA24DE) 240sx's clutch replaced back in august , and afer about a week of driving I started to hear what sounds like a bearing noise when the clutch pedal is depressed. Now assuming it was the throw out bearing i went ahead and had the clutch and throw out bearing changed again in december. Well the sound is back and I am at a loss

-noise only happens when clutch pedal is depressed-only happens like one out of ten times i put the pedal in -fluid level in transmission is fine.

any ideas/advice?

possible pilot bushing but the fact that it goes away when you replace the throwout bearing is kind of a giveaway. what kind of throwout bearing have you been using?

I initially used what came in the clutch kit from autozone. I'm not sure what they used when they replaced it the second time, but i will go to the shop i had it done at and get them to look at it. thank you for your help
