Sounds like the new master/slave isn't pushing the throwout bearing arm far enough.
Were you having these symptoms before the new master & slave?
As far as my problem goes, I'm just going to pull the tranny on it. It's started growling now on start up, RPM & vehicle speed have no effect on it, nor does the position of the clutch or. Does it any time the engine is running regardless if it's in neutral or a gear. It's not motor noise. It's definitely coming from the bell housing. Leading me to think the pilot bearing is about to crap the bed. I'm just gonna rebuild everything. Clutch, flywheel, master/slave, throw out bearing, pilot bearing, everything. I want to be done with it.
There goes my money for new tires.
