no one has tried it, you would be thre first one!
I'm really curious as to if it would work. It might, it might not. Do you have the clicking noise when you turn off the car from underneath?
To do the "fix", all you have to do is unbolt the actuator motor (I think you said you did this already), turn the white gear 180 degrees, and put the motor back in. The worm gear will seat itself properly (I have tried this with my messed up one, so you should have nothing to worry about). Reinstall and then let us know!
If you can drive a few times and try to push the X-drive system so that it has to work, and report back many of us would be very eager to hear how it works. Good luck!
