Snapping sound from rear
I came into the next century and got a C6 corvette. 2005 6spd. To me it's new. Only 16K miles. Has obviously sat a lot. Been really quiet till the last couple of days. At first I heard a momentary snapping, or plastic type cracking sound under acceleration. Yesterday I heard the sound during some abrupt braking, and then again on acceleration. I know my 200K mi c4 like the back of my hand but haven't raised a wrench to this car yet. Anyone have any knowledge of the C6 and where to start? it's a dual mode suspension tour vs sport selection. Thanks!

My solution, which has been working well for 100K+ miles, was to lubricate the splines and the flat at the base of the splines (important) with Honda Moly-60. Other people chase the noise with ever-increasing amount of torque on the axle nuts, and even apply Locktite, but I'm not crazy about those solutions.

From your description it could be the half-shafts. When the interface between the half shaft and the hub is dry and rusty, it can make an audible creak on torque reversal. So it will creak once when you accelerate hard, but not again until you engine brake.

I should add that it's possible that this doesn't address your particular problem. It's difficult to diagnose noises over the internet.

I'm referring to the splined shaft that engages the hub, not the CV joint itself. In other words, the shaft that the axle nut threads on to. Here is a description with pictures:
