Question about 2003 Honda Pilot
I just replaced the engine oil, differential fluid and rear VTM fluid on my 2003 Pilot. Now all of a sudden it is making strange sounds -- coming from rear hub I think. Does anyone know why it is doing this. Never made this noise before. Sounds like a high to mid-pitched humming/grinding sound.
Once you add fluid to the rear differential, you should drive a short distance in forward and reverse. Then take out the fill bolt and add VTM-4 fluid to fill it again. It will take more fluid since driving it a short distance helps the fluid move into the rear end. The noise is probably due to not enough fluid. The fill procedure is fill it once, drive it, fill it again.

Not a solution but check to see if the limited slip differential is at issue. Honda extended the warranty on some models back in the day (in my case up to 108K miles), but I still battle this annoying, dreaded grinding noise on my 2004 Civic hybrid (now at 169K miles).
