Car rolls

That actually makes it more likely. Almost always when the CV pulls out is because it was removed and replaced not all that long ago. Apparently the spring clip wasn't fully engaged or for some reason was able to pull loose.

With somebody's help it will take seconds to determine if it's the drive prop or forward.

If it's the TC spline issue, the drive prop won't move. I think you can get a peek of that somewhere without removing any underbelly, maybe through the left front wheel well at back of dif.

In the five or six different cases like this, when it's been the splines the car wouldn't roll, it was always the CV axle loose.

When TC splines the failure was slow over time : months. When it was the CV axle it was instant and sounds like grinding gears

The reason some people can get away with pulling front drive propeller and default to rwd use they have x-drive with a TC that disengages the front axle when the car isn't moving, and somehow figures out when no resistance on the front axle to not try to apply power forward. Pre x-drive the TC is open differential as are both differential so any wheel spin is fully regulated by the abs system.
