No issues with leaking from my diff, 112K miles, though I did pull the driveline twice to do tranny and clutch jobs. The transmission- was another matter :ack
2002 Z06, and it leaks so bad I shouldn't drive it until it is fixed.
This is from taking it to the track and driving it pretty hard. The differential and transmission got really hot, this is actually a common problem with Z06s (GM installs transmission coolers on European Z06s, but not on the US versions). I will be ordering differential and transmission cooler kits from Doug Rippie Motorsports which shoud take care of that problem.
These kits are not cheap, not many manufacturers making transmission cooler kits for manual transmissions. GM sells theirs for about $1000, DRM goes for $650 for each for diff and tranny.
I will admit, driving the Z06 on a road racing track was INTOXICATING!
Can't wait until it's fixed and ready to go again.

Mine has leaked twice - once at 10.6K miles and than again at 18.8K miles. The last repair seems to have solved the problem at least for now - car has 32K miles on it now.
