I tried to capture the noise in the car, LMK if you can hear it.

You could be a little more scientific about it by testing each of the joints individually to see if there's any particular section with excessive slop or backlash.Originally Posted by Rawyzf
eg:
Start at the gearbox output flange(A)
Hold flange A stationary and try to rotate the rubber coupling(B)
Clunk Y/N
Next hold the rubber coupling(B)
Try and rotate the front secton of tailshaft(C)
Clunk Y/N
Next hold the front section of tailshaft(C)
Try and rotate the front section of splined shaft before the Universal joint(D)
Clunk Y/N
Next hold the front half of the Universal joint(D)
Try and rotate the rear section of tailshaft(E)
Clunk Y/N
Next hold the rear section of tailshaft(E)
Try and rotate the rear rubber coupling(F)
Clunk Y/N
Next hold the rear rubber coupling(F)
Try and rotate the diff pinion flange(G)
Clunk Y/N

Thanks everyone, I'll continue to research the issue and report back.
What I have going on isn't normal, I know that. It's also not the inherited noise from aftermarket bushing/braces. I've had all these parts on for 6 months. This has been getting bad/worse over the last 3 months.

I have the same issue. I just took my car to the dealer for it. At first they couldn't replicate it so I went back and showed them how. Prior to taking it in I changed out the springs, shocks, rear cradle bushings, differential bushings, front lower control arms, and the strut mount bushings, it still happened. Dealer tried blaming the new suspension on it the last time I talked to them but who knows what they will blame next. Hope to get a call soon.

Great info. Please let me know what they blame or fix next.
Do all of the g8s come with 100k power train warranties?

They should.
Also, I have that noise too but very, very slight and minor compared to that. Comes and goes. Yours is not normal although I'm just stating the obvious.

I'm not going to bother bringing mine to the dealer...too many mods for them to blame it on. I sure would like to know what they come up with though.
I'm ALMOST hoping that it's the diff; I still have the 2.92 and I love the 3.70 but the hit on fuel consumption is starting to get on my nerves ;-(
Made an appointment for tomorrow, will keep everyone posted.
