[Mgs] Clutch problems.

[Jim Juhas]

I don't know if your car uses a roller bearing or carbon bearing, nor 
did you say that this had been operating correctly and that this is now 
a failure.

If this is a recent failure, I would suspect the throwout bearing.  I 
had a carbon-type one fail abruptly, caused grumbling sounds, and then 
the clutch could not be disengaged.  The carbon had disintegrated and 
fell out of the shell.  The steel/iron remainder of the bearing against 
the pressure plate accounted for the noises.

I have had roller-bearing throwout bearings fail on 60's-era Chevelles, 
and they would make a lot of noise before their failure. The carbon-type 
failure was abrupt, a snap, no disengagement, and noise when the pedal 
was depressed.
