Hmmmm.... "whirrrr" sounds... yeah I had some of those.

I am not too sure when in the time-line of events this thread was a hot topic for me, but I do know that afterwards at some point in time I was driving down the freeway and pole vaulted the rear end of my truck with the drive shaft. So that being said, I am leery of giving any advice other then have a good professional check it out for you. Especially after causing that much damage to your undersides!

the red smelly fluid is obviously tranny fluid and i believe the black box is just a wieght to balance ur transfercase, if it is aliens, id leave the rig with ur wife, take a picture and post it

 

yeah..so i had a better look at it this afternoon. the bracket holding it has completely folded up and that box is now pretty much upside down. ill have to bend it back to somewhat normal shape..just to get the bolts off. so far, no vibrations. its still there so still counteracting the vibrations im sure...just not in its original location

...yet another thing to put on my fix list..
