Clutch issue diagnostic help

[Captain Crunch]

Hey guys, I have an 11 Gt500 and Im getting some grinding noise from my transmission while letting the clutch out. It is faint while in neutral and letting it out. With the clutch in I can move the tranny into any gear without issue. When I am in any gear and start to let the clutch out i get a pronounced grinding sound. The car will move and drive once the clutch is out. Could the throw out bearing cause this issue?

I'm sure it could, but I think the pressure plate could also cause the issue. Same labor either way. I don't know how many miles you have on the car, but if I had to change one or the other, I'd probably do both.

How many miles on the clutch? My TOB exploded at 75K and had to get towed to the dealership.

Car has 52k on it but clutch only has 7k miles on it. It is an Exedy.

Was the slave cylinder changed with the clutch?

My friend owned the car before me but he doesn't remember...damn rich kids. Haha.

I plan to tear it down soon. Should I go with an OEM slave?

I did when I installed the RXT.

Im curios will I know immediately what the problem was or will I need to measure some things?

You can cycle the slave and actuate the bearing to see if you hear anything, but it takes quite a bit of force to move the pressure plate. There I think you'd just do a visual inspection and see if you see any obvious wear areas that seem out of place. Now you could find a shop with an axle press and move the fingers that way. I'd also look for any strange wear patterns on the flywheel, pressure plate and floater that may indicate some problem you can't see.

Ok thanks for the info. Much appreciated. I figure there will be some obvious wear at the contact point that the grinding sound is coming from? Im not sure what would be making that specific sound .
