I’m hoping someone can point me in the right direction. I have a 2008 H3 and I lost front wheel drive in all three settings. However I was able to get the rear wheels to move in 4Low for a short distance until I lost that too. Now when I place the vehicle in park it rolls. I have no forward, reverse or ability to place the car in park. Would that be the front differential and transfer case.
when the gas is pushed the front drive shaft does rotate but will not go forward. When placing the car in park I hear a loud clicking noise coming from the transfer case.

 

So, if I understood your post???

Lol.

The front ds turns when placed in drive?
Is there pop'n or chattering while pushing accelerator ? Meaning in drive and 4L engaged...
Does the front differential attempt to rotate the tires?

Have you drained the front differential and removed the cover to inspect it?

You could have a damaged shift fork. A damaged transmission. A damaged front differential.
Time to test the vehicle with all four wheels off the ground.

 

POPCORN

 

Miles on the H3. Recent work done?

When was the last time you changed the Trans Fluid and filter?

 

Looks like a bad T case , drain oil and watch the color of it. Maybe the fork of the T case shift is out
