Clutch throw out bearing wearing out on 99 nissan pathfinder

The noise occurs when changing gears from first to second and sometimes third. It seems to occur when pushing the clutch petal in. It only last for the first 2-3 mins of driving. The noise stops as soon as the clutch pedal is let out. Sometimes it doesn’t occur at all. It seems to occur more often on cold mornings or after the cars been driven for a long highway drive. I had an old 92 pathfinder that did the same thing at just over 100,000miles. I replaced the clutch on that one and solved the noise. That was a while back but I seem to remember something about a worn bearing also (guessing it was the throwout bearing). What does this sound like to you? Pilot bearing? Throwout Bearing?
Thanks for any input you may have.
