It does sound like the TO bearing. Two things kill the bearings. 1. improper freeplay adjustment in the pedal. 2. Sitting stopped with the clutch depressed. I did get a bad bearing once. I installed it during a clutch upgrade and had to pull it right back out. The TO bearing should easily outlast the clutch. I've never had one fail, but I never sit with the clutch depressed. I shift into neutral at every light and every stop lasting more than a few seconds. Yeah I'm one of those guys
If the guy behind me doesn't think I'm moving fast enough, then I shift into reverse
That clears up that noise pretty quick. Bottom line is, you can make a TO bearing last if you give it a little effort, or you can kill them with bad driving habits.
