A while back ago, I had made a comment about this weird mosquito sound coming from the left side under the hood (keep in mind, mines a RHD so parts are flipped). The sound continued for a bit and eventually went away with no issue. Recently, the sound came back, but now it’s constant. Before, it would appear beyond 40mph at 1500/2000 RPM. Now, It’s whenever the vehicle is moving in drive (except for 10mph and below). Weird noises have been coming out during this cold season, so deep down I’m praying it’s because he’s cold. The radio fuse is pulled (I was having electrical issue before). Ugh… I’ve been chasing this for a while.. any ideas? I have a video of the sound below.

Couldn't tell from the video. Could be the front driveshaft, hub bearing or axleshaft u-joint. A quick check would be to remove the front driveshaft and take it for a drive. My guess is a hub bearing.
If it's the front drive shaft, you need to either quit driving it, or remove the shaft. If the double cardan joint at the transfer case seizes, it will destroy the transfer case. You can drive without the front drive shaft installed as long as you want.
Could take the belt off and see if the noise stops. Or spray a little water on each of the pulleys and see if it changes.
