General Question (mAC) Pressure Plate Failure

[Larry C Leung]

Phil, 

Thanks (I think). I do get a "whirring" sound some of the time
when the clutch pedal is released (clutch engaged). It gets
quiet when the pedal is depressed. To me that sounds like
the TO bearing is okay, but that means some other bearing
is suspect. Arghhh. 

Keep us posted.
