After having two shops look at my vehicle, it appears that indeed, I got some puking from the vent tube out of the front differential.
I had a shop that specializes in differentials evaluate both diffs and the transfer case and replace fluids. No issues were detected.
I guess I'm good to go, but I do like the idea someone had on these forums to put a plastic bottle under the hood behind the air intake filter housing and routing the breather tube into it to catch any more output should it happen again.
Would be less of a mess! As it is, I have that differential fluid on my exhaust system under the driver side and it smells terrible right now.
I need to get some degreaser on it and wash the underbody down...
Hope this thread helps someone!
