OK here is the TRUE answer.

Noise when the clutch is ENGAGED (IE pedal off the floor).

It is the Input shaft bearing. Think about it. The throw out bearing is ONLY engaged when the clutch pedal is pushed down ( clutch = disengaged). The throwout bearing sits on the clutch fork, therefore is only active when the clutch is disengaged.

The Input shaft bearing spins, whenever the input shaft is moving, it is the first bearing to be spun if youd like to look at it that way.

There is a lot of confusion, TOB noise would be when the clutch pedal is pushed to the floor, input shaft is when the clutch pedal is off the floor.
