I think the bearing in my YS1 may be bad...
but it doesn't sound like I though it would...I've had a bad throw-out bearing before...it was whinning until I would press the clutch pedal in. I thought the input shaft bearing might sound similar.
I hear kinda of a soft knocking until I press the clutch pedal in......or take the tranny out of gear.

I think the input bearing is spinning at idle...so I think I should hear it at idle too. I only hear this in gear...

what do u guys think?

 

Mine made a whining noise at time, but it also sounded like of like a soft rattling/knocking, but it did go away when the clutch was pressed in.

I replaced the bearing, and while it was better, it wasn't fixed completely. I think some of the other bearings in there were fooked up too. So if you crack the tranny open to replace the input shaft bearing, you might consider replacing the other mainshaft bearing and countershaft bearing(s).

 

and replace all the oil seals while you're doing it. they're cheap.

bad ISB makes a low knocking sound at idle with clutch out in neutral. Clutch in, it won't make the sound UNLESS you're rolling.

hrmmm...well I don't hear it at idle...only in gear and rolling. i press the clutch in and it seems to go away...

I also put the car up on jack stands and had my buddy run it through all gears and rev it up to like 4k while i was underneath listening for the source of the clicking/knocking....it won't make the sound unless it's on the ground though.

IF i do end up dropping the tranny I'm definetly going to repalce all bearings and seals...
