That sounds like something i have, but not as clear as mine.
I attached sound file from inside the cabin with doors and roof on, listen if that is what you hear.
What i know for sure (if yours is same as mine) it is not a front dif, not engine rpm related, not drive shaft, and not 4wd or 2wd dependent, changing TC or trans oil makes no difference. It is rpm related only when in transmission gear, and not all gears make that sound (my 5th is quietest)
Around 40 sec and 1 min i was playing with gas pedal, and it is audible how sound fluctuates
