When searching for leak fixes for my Quota I found this....

"Leaky Rear Drive?

  The best fix for the Sport I and Centauro rear drives that leak is to let the pressure out when it's hot, then tighten it back up. The only problem is that if the seal is actually blown, you may have to replace it, then do this procedure. The earlier '97 Sports were claimed to have the wrong size nut that spins inside the pinion seal. This is not true. I've replaced those with an "updated" version and had the same problem. It wasn't until a couple years ago that I discovered the simple "suction" fix works great. Please do not install a breather kit with a hose. It will just boil out the hose onto your tire anyway."

I like the simple, easy and no cost option. Going to give it a go on the Quota.

Might work if the parts are machined correctly.

Update at 10,600 miles.

After riding on the new hub for ~5000 miles, the rear drive started leaking again.  I happened to be at the dealer when it leaked so I left it for them to inspect.  The following week, the dealer called and stated that they couldn't see anything wrong with it so they had pushed it to Piaggio for guidance since this bike is on it's third rear drive leak.  The bike is out of warranty, so I didn't have much hope Piaggio would do anything.  To my surprise the agreed to replace the rear drive if I would pay the labor of $230. I now have a new rear drive and hope that my leaky rear drive problems are behind me.
