If the car jerks and shudders AS the clutch is being engaged, a 'blued flywheel' could be the cause. If the grinding is apparent while the engine is running and the clutch pedal is depressed, it is probably the throwout bearing. This symptom is common to any car with a bad throwout bearing and not just Saabs. This part should have been replaced when the clutch was done (as well as a rear main seal and a pilot bearing). If it is indeed a throwout bearing, the clutch needs to come back out to replace it. I would replace the other, afore mentioned parts, at the same time if they were not replaced. It may have been a new bad throwout bearing...
