Default leak coming from under car, HELP!

I was looking under the car and seen a small puddle of oil from the middle of the car. I'm not exactly sure but am thinking it is the transfer case.

I attached a couple pics for you guys to see, please let me know if it is. I was looking through the threads and found that it can be fixed with just replacing a seal. I just hope this will be an easy job!

I couldn't find any threads with any steps & pics on how to work with this procedure. It's a 2004 model.

To me it looks that it is more to the Transfer Actuator leak, And the oil has spread over the T/Case. Your T-case is just fine. Anyway you could the proper inspection to find the leak source. It is the O-Ring to be replaced. Here is the TSB, and work around to solve this problem. Hope this helps.

Thanks guys.

I attempted to shift from high to low to neutral, etc and it made a grinding noise each time I did it, guess the oil must be almost out, definitely need to refill it in the meanwhile. I just hope I didn't screw anything up while shifting all those times!
