Slinging Oil

Looking around under my truck doing some paint touch up from my off roading trip I noticed some oil on the frame cross members-. looking closer it was also all over the front drive shaft/casing, diff, and the oil and tranny pans. It is more of a sheen with some small, very slow, if any, drops (like it doesn't even leave a spot on my driveway).

I wiped a it away- and I'm going to keep watching it- but I think a trip to the dealer is in my future. Before I go:

Anyone had issues like this before?? I'm wondering if oil from the front diff got blown out the breather or if a seal cracked somewhere??

 

torn CV boot?

 

Negative...Checked those first- and it's liquid oil not grease/gel.

 

No...I didn't want to put it up on the ramps and I didn't have space to get under the truck with a camera.
I'll have to look tmrw...maybe I'll ramp it and see what I can see...Thanks for the ideas Chris.
