Spinning noise while in motion

2005 Tacoma 4x4 V6 TRD Sport

Our Tacoma started making a spinning noise when in motion. Coming from underneath the truck.
We haven't had a chance to get it checked out yet. Wondering if anyone here recognizes this sound?

It's especially noticable when the sound has something to bounce off of.
(Apologies for the road noise)

 

Look under and see if anything is wrapped around the drive shaft.

 

Took a look down there - nothing is wrapped around the driveshaft.

 

Really hard to isolate the noise from road noise. Maybe check u-joints & carrier bearing. Long shot, but check fluid levels in t-case & diffs.
