Default Whirring Sound

ok this only happens when the clutch pedal is pushed in, it will make a "whirring" sound and you can also feel it through the clutch pedal, it's like something's making very small contact w/ the recipricating flywheel?

also, when the car is making a WOT shift, i can hear a "grunting" noise coming from the clutch area? it's almost like the whirring sound when the clutch is pressed in, but it's a little more louder and deeper noise.

ya'll think this is a sign of the throwout bearing going bad?

clutch does not slip at all, it grabs and holds good, just got these wierd noises in which are not normal.

car is a '99 Z28 w/ stock hydraulics and stock clutch.

its a good idea to get both at the same time, but expect to take 3hrs to do the master. i dont know the prices of the slave/master offhand.

Keep in mind, this car has 111K miles... on a supposedly STOCK clutch.

I had the car before him, and i bought it at 42K miles... with a "STOCK" clutch.

So noooooone thinks it could be the clutch?! It's the wierdest sound i've ever heard.

if theres a wierd sound coming from the clutch assembly you might as well replace the whole thing.

the 01/02 slaves are updated for better engaging and disengaging.
