Looks like something is leaking above the axle-- if on the left, it can be a power steering hose.

Axle seal!!! very common issue with every 4x4 gm truck from 2000 up! My past three trucks did it. and now the one I have now is doing it. its a very slow leak. I just keep an eye on the fluid level. dont let it get low!

I say axle seal to, and they aren't always easy to change, they are held in by round clips in the diff and they some times flatten out and you can't pull them out, have to split the diff and cut them.
