I have a 2001 durango. I can start my car put is in gear gas it, my drive shaft spins but my car doesn't move

Check the rear U-joint. If it's good, you either have a snapped axle or an issue in the differential.

Inspect all the U-Joints-Don't get this one: driveshaft spins but doesn't move

A broken axle will allow the driveshaft to spin but not transfer power to the wheel.

The drive shaft spins but the wheels don't turn

We have a few possibilities:
1: with a driveshaft having a center support and bearing, a snapped U-Joint at the rear.
2: Center supported driveshaft, snapped rear yoke, either on the driveshaft or differential.
3: Pumpkin or pinion gear in the differential missing teeth or broken.
4: Snapped axle.

I narrowed it down to my transfer case. And a friend told me the bearings. Look at the picture and let me kno and also how much to fix It

THIS COULD HAVE EXTENSIVE DAMAGE IN THE TRANSFER CASE

REALLY NEEDS TO BE TORE INTO TO SEE THE EXTENT OF DAMAGE...DAMAGED BEARINGS NO LONGER CENTERING THE INTERNAL SHAFT COULD THROW SHAFTS OUT OF LINE AND MAKE THINGS WORSE INSIDE

JUST LOOKING AT THE PIC, RECKON THE BODY WEDGED UNDER YOUR RIG HAD ANY AFFECT?...............LOL!

Go Navy! WE beat Army!
I second what CJ said. How much to repair will depend on what is needed to fix it and how much the shop charges for labor.
