Transmission problem -knocking noise(Video included)

My friend wrecked my g37x causing some minor front end damage.. It wasn't a huge problem since i work at a body shop and he reimbursed me for time/parts.

I pulled the engine/transmission out, fixed the body and then put everything back in.

My issue now is that there is a loud knocking noise coming from the transfer case/drive shaft area. The driveshaft starts moving as soon as the car is put into drive/reverse even though the rear wheels aren't moving.
If I try driving the car the rpms will go up but the car will hardly move (As if a really bad clutch).

I'm waiting for Consult 3 to come in the mail but for now I thought i'd ask for suggestions. Anyone?

Looks to me like the driveshaft is hitting the exhaust? Possible the exhaust got bend?

No the exhaust did not get bent. It isn't hitting the exhaust.. I forgot to mention that when the car is put in Park it still rolls freely as if Park didn't engage. I'm starting to think something happened to the transmission or transfer case at the time of the accident.

Are you sure you put the engine and trans back in correctly and something isn't misaligned or missing. You did say you pulled them both out afterwards.

They're back in correctly.. I'm leaning towards something breaking inside the transfer case during impact since the car rolls when in Park
