Not sure of exactly how many miles on the clutch right now, but it was put in the car back at the beginning of August
2012. So likely I've got a couple thousand miles on it in the 16+ months it's been in there. I babied it for the first 500 or so miles for break-in, and have never really abused it at all the entire time. If anything, I still treat the car like it's made out of egg shells.
I have read accounts of people complaining about the Centerforce clutches sometimes being noisy, so it just may be I got one that isn't as quiet as I would like. Just not even tempted to pull out the drivetrain just to replace the clutch to see, I guess. So if that intermittent screech is a warning of some sort of impending failure, I'll just wait until what ever it is breaks, THEN fix it. If the noise is just an irritant, then I can live with it till I NEED to pull out the drivetrain, and then try to figure it out.
If I thought I could reproduce the noise on demand, I would take it to Shane at the local Chevy dealership just so I could get his opinion about what is going on. But it's just not that predictable.
Heck, I've probably got some video around here somewhere that I took while driving the car where the noise makes itself evident. I thought about getting one of those GoPro camcorders and trying to mount it at strategic spots to try to pinpoint where the noise is coming from, but I'm not sure that even that would work.
The practical side of me wants me to just not worry about it, but the perfectionist side sometimes gnaws on my leg to try to figure it out.
I'm trying to keep that perfectionist side in check lately. It can be a pain in the ass sometimes.
