2007 FG clutch rumble?

[unkamonkey]

HMMMMM
I crawled out under mine a few years ago and determined that the push rod was loose enough to possibly fall out on the clutch system. Alright, adjustment time. I couldn't get the lock nut loose... So even after several applications of good spray stuff I still couldn't get it loose. I just put on another spring out keep the throw out arm in contact with the push rod. The clutch works fine that way.

No adjustment at the slave on 2000 model. It is passive adjustment that it does itself. If you notice the slave cylinder is very long and the piston sits where it needs to with little or no pressure on the bearing.
This is what I would do :- Start engine and depress clutch peddle - release - listen for noise , if noise.
Leave engine running , climb under and pull on clutch fork to return piston further into cylinder (this will give you more clearance between bearing and clutch fingers). If noise is still there then not throwout bearing.
Adjusting the master Cylinder will NOT give you more clearance on throwout bearing (unless the master cylinder is very much out of adjustment but that is a different situation). It will only change peddle position.

So if there's no adjustment on your model year, is it possible that the spring which pulls back the clutch fork has come off and there's nothing to pull the throwout bearing off the pressure plate?

Okay thanks for that, makes sense!

Further investigating today I found a loose bolt on the driveshaft where it mounts to the parking brake so I'm hoping that was it.

There is no spring, it has a captive head on the rod where it goes into the clutch fork (so can't fall out ). Like I said it is a passive clearance ( as in self adjusting ) on the bearing to fork fingers. If a spring was fitted then there would become too much clearance because it would push the piston back into the clutch cylinder too far.
Passive Clearance :- Because it is all rotating and the bearing can move away from the fingers it does so. Then no load on bearing. Believe me this is common on a lot of vehicles.
