          I am going out on a limb here....... but guessing by your name (juiced) and the fact that you are a M6, I am assuming those u-joints have seen a few very hard clutch drops.

          Is that a stock LS1 driveshaft?

            It could be his trans. I've gone thru 3 transmissions & when ever my trans starts to slip I get unusual vibrations. Feels like it's the ujoint but it's just my clutches in my trans triying to grip but slip.
