Major trans/diff/coupler issue, need help!
Driving home from dinner, rolled into it in first and paddle shifted into second around 5k rpm and it popped and rev'd. Then sounds like rotational flopping. I thought I broke a half shaft or something.
Looked under the car and no sign of anything. Putting it into drive or reverse gives like winding type sound, not really grinding.
Haven't even put a full tank through the car since I got it, and now this!
Could it be the torque tube, or couplers? Just hoping its not a full trans build, or diff.

Jack up the rear and try spinning each wheel while the car's still in park. If both wheels spin freely then you broke the output shaft in the transmission, if only one spins you likely broke a halfshaft.

Definitely not common unless you had wheelhop or something (which is common). Good luck and let us know what you find.

Well went to the parking lot where the car is, and it seems to be a half shaft down at the driverside wheel. Can spin the wheel in park, but the half shaft doesn't spin. Seems like its right down at the spindle.

It is common for the 05-08 C6 CV axles to twist off right after the outer spline. Replace the axles with C5 units and forget about it.

Well, got it all put back together last night. Pretty straight forward, but it was 108 here yesterday which made it less than enjoyable 
Seems like a fairly typical break, replaced it with a C5z which will hopefully stand up to my massive amount of stock with a catback horsepower!!!!
