clutch chatter/rattle noise
 

here's the full history. 5 years ago my dad and i rebuilt the sr-4
tranny (stuck in 3rd gear) in my 80, cj7. it crapped out within a
couple months, (stuck in 3rd gear again) and it sat since then. so i
dropped the sr-4 and picked up a t-4. rebuilt the t-4, new bearings
and seals, etc.. stabbed the tranny back in, bellhousing never
removed. pretty sure i replaced the clutch 5 years ago, but i've slept
since then.
now to the noise. if sitting idle in neutral (while tinkering around)
the noise never occurs. a soon as i press in the clutch i hear a
chattering/rattling noise in gear or out. as soon as i disengage the
clutch the noise stops. i checked the linkage and it's not loose. i'm
going over to work on it tommorow and will check if linkage is to
spec. what could be rattling around? my little helper put it back in
gear when i wasn't looking, so i've started it in gear and it lunged.
(good thing something told me to chock the tires :) ) so i'd say the
clutch is grabbing pretty good...
any suggestions would be greatly appreciated

Sounds like a issue with throwout bearing being bad or improperly
installed. The bad part is you have to pull tranny to inspec/repair
it. When you changed trannies to you confirm that there was no
difference in throwout bear design or needs?

My guess is the grease has dried out in the throw out bearing. No
fixing it short of talking the tranny out.

I would try it for a bit to see if it loosens up before ripping it apart.

What I want to know is how in heck can you take a tranny off without
taking off the bell housing?????

Best guess is the throwout bearing. Dried grease, etc. Next guess -
because it sat so long - would be rust on the face of the throwout or the
clutch fingers. I've seen rust there act like a coating that squeals
forever. That squeal should only happen as you engage/release but go away
as you increase the pressure. Either way, you'll likely cure it with a new
throwout - but you still have to pull the tranny.
