[s-cars] Loud Scraping noise: Transmission? Driveshafts?

[Paul.Park at colorado.edu]

Hey guys,

The Audi gods have punished me.

Under relatively hard acceleration in 3rd gear(not past 5KRPM), the car began
making some awful scraping noises. I thought that my entire exhaust was hanging
on the ground. As I go faster, it gets louder. If I come to a stop, it takes a
while for the scraping noises to stop, as if whatever's scraping, is rotating
to a stop.

When I mean loud, I mean dominates the cabin, even with windows closed. It
sounds really loud outside of the car as well.

I just did the clutch, so could I have messed up aligning the driveshafts? The
car engages gears fine, it shifts fine...so I don't know what else it could be.
