"Hum" from Front End while in 4WD High

[907.Tony]

Hello all. I have a 2020 Bighorn 5th Gen. Lately, while only in 4WD high and making turns "in town" low speeds, while in 4WD high (snow/ice conditions in Alaska), I'll get a "humming noise" in the front end.

Had the truck raised and tires off, didn't see anything obvious. It only seems to give me that noise in 4WD high, not 4WD Auto or 2WD. Any experience or thoughts on possible culprit(s)? Thanks in advance!

I would chalk that off as normal drive-line noise due to possible binding of the axles, unless it is really noticeable.
