This one's been driving me nuts, guys. Under load, when accelerating, my M1009 makes a light chirp/knock (really more of a tap -- it's higher-pitched than a knock) . As soon as I let off the pedal, it's gone, and if I accelerate very modestly, it doesn't make noise. I can't replicate it in park or neutral. I have ruled out both alt belts, flex plate bolts, dampener, and don't think it's u-joints (they feel good and I greased them up with no change in the noise).
How far should I go to check this out? I see that someone's pried on the PS pump in the past to try to tighten that belt up; maybe it rubs a bit internally under load?
Am I being paranoid wondering whether it might be bottom end noise? Do they ever "chirp" The bottom end issues I've dealt with were all pretty low knocks.
Here's the thread I started a bit ago when I was trying to track down the noise:

Thanks in advance!
