The real economic advantage will be from being able to grease the U-joints and not shelling out a U-joint on a road trip and/or having to go back to the drive shaft shop to spend another $100+ on a U-joint replacement in 50,000 to 100,000 miles.

I'm no expert, but I would think that it would take less power to turn the aluminum at the same speed as a steel one, which should have a tiny mpg benefit. I'm not saying just that one change would equal 1 mpg. But maybe if it was combined with some other mods it might show a measurable benefit.
