Is this a transfer case leak? gear oil?

Wondering if this is a leak of the transfer case? Could it be the front or rear outputs or maybe the transfer case seal itself?

 

What leak? The ground looks completely clean.

 

Hard to tell where it is originating from.
Almost looks like it is leaking from the front and down towards the back.

 

wipe it off with a rag and monitor it for a while.

 

thats pretty clean for 8 years old.

 

So clean it looks like OP has a new truck and hasn't updated profile.

many many pics though

 

Clean it with some engine de-greaser and monitor. Much of that oil's been there for a while. Probably a seal in the front of the transfer case, but your (many copies of the same) pictures don't give a full view.

Maybe you have a local shop, other than a dealer, that would put it up on a lift and take a look.

 

I just hit mine with a de-greaser and wiped it all down today and am going to drive to work tomorrow and get underneath to try and see if it was a messy transmission oil flush or an actual leak.
I agree with @OldSchlPunk and you do the same before you even take it in.
