Awesome thanks for your help, this may be my issue!Yes mine noise was more pronounced on uneven roads and concrete less so on smoother asphalt. Noise was only coming from the front and I could hear it at any speed. My car also developed jerky shifts and hesitant on accelerating when I was waiting for parts. I realized later that I ran winter tires on the front that little bit outside the factory size 235-40 instead of 225-40 rear being the same. Maybe that’s why my transfer case developed the hum. But propeller shaft was also noisy for some reason. Def ask your dealer to check those areas.
How long was the repair? Lol
