Quick test to eliminate at-least one possibility; with the car running and in gear, hold the brake and accelerate, to "simulate" high load without letting the car move at all. ie, everything is under torque but the diff isn't moving.
I had a grinding noise not long after I bought the WH (2nd-hand.), had a Jeep stealer look at it as I was a bit scared to work on it myself at-first.
After a test-drive, they told me the front diff needed to be inspected and probably rebuilt $$$.
Turned out to be the cat rubbing on a bent bash plate

Sounds very unlikely in your case (especially if the oil change worked for 8Kkm); but still never underestimate the stupidity of some of these clowns.
