Brian,
The wheel hub is SPLINED to the outer CV shaft, the outer CV hub is SPLINED to the outer end of the main axle shaft, the tripod bearing is SPLINED to the inner end of the main axle shaft and the tripod bearing drives the companion flange (aka. the inner driver) which is SPLINED to the side bevel gear in the differential. Every place that there are SPLINES there is the possibility that those SPLINES have been stripped. If that happens you lose torque transmission from the transaxle to the wheel and, here's the funny part, if you "disconnect" one front wheel in that fashion you'll have no drive at all. That's because the differential will do what it was designed to do and split the torque in favor of the axle with the least resistance. An axle with zero resistance (aka. traction) will get 100% of the torque while the good axle gets none.
The first thing to do is inspect both axle assemblies from inner driver to hub looking for obvious problems like a broken axle shaft or inner driver or somethin. If the car ever had it's axle shafts swapped out there is the possibility that a short shaft was put where a long one was required and your antics stressed it to the adios point. You'll be able to detect that by feeling the inner driver boot to determine if the tripod is popped out. Otherwise you may have broken one or more differential gears including the ring and pinion or this could be a clutch problem. I suppose that you may have broken the clutch shaft.
I guess that I'd put the car in gear, jack up one front wheel and roll that wheel. I'd expect that you won't be turning the engine as would normally happen (because you have no drive) so while spinning that wheel see if its inner driver is turning. If so then the broken part is either in the transaxle or in the axle on the other side of the car. If the inner driver isn't turning then you've isolated the problem to the axle assembly (Inner driver, tripod, axle shaft, CV hub, CV shaft, wheel hub) on the jacked up side. So if that inner driver turns when it's wheel is rolled, put it back on the ground, move the jack to the other front wheel and do the same thing. If both inner drivers roll with their respective wheel then the problem is; stripped splines on one inner driver shaft, Internal transaxle problem, broken clutch shaft or other clutch problem. At that point you have to start opening things up for inspection dude. Donuts huh.
