I see nothing wrong with the pilot bushing. End of the main shaft looks and feels fine. We greased the pilot bushing and the input shaft lightly when we installed it. I have the previous throwout bearing (it didn't make noise) from before, it only had a few 1000 miles on it. I pressed the two throwout bearings together in the vice. No problems with either. both spun with no noise. Could it be that we didn't put enough grease in the pilot bushing before we installed it? or it dried up? I will call Passon and Brewers to see if they have any answers also. Also yes it did it in neutral.
