There is a coupling gear between the transfer case and the transmission. They are known to shear the splines out of the inside if them. Especially if driven hard or something breaks and causes a severe impact to the drivetrain.
Easily fixed but the gear is high dollar. ~$500+ not installed. Not sure if they are still available but I can check.
Saw where disconnecting the battery and turning the headlights on and key on for 5 minutes sometimes fixes it. Worth shot.

Thanks for the feedback, but we found the issue, and that is there are like 7+ rear CV options for my car. I had a dealer sourcing CVs from all over the state trying to find the correct fit. We finally got the correct CV in place and she drives like a dream again.

 

I was going to mention that but you said the driveshaft wasnt turning.
I had that happen on a RWD version. Had to replace axle for some reason. Put it back together and drove a block to the next stop sign. Went to take off and nothing. Had to tow it back home, pull the axle and get another one.
SXT's with 4 speed trans takes one axle while ones with a 5 speed take a larger one. I had a 4 speed axle in a 5 speed car. They'll fit, justbthe splines wont engage with the hub to drive the car.
