Whistle while driving
Lost here...I have a resonating whistle sound while I'm driving, it speeds up when I give it more gas and gets quieter when I let of the throttle can't wrap my head around what this is. Sometimes I will be off the throttle and it still makes the noise. Any ideas??

Obvious checks have been completed? Driveshaft u joints, diffs and wheel bearing?

If I'm reading correctly (which may not be the case due to the massive hangover I'm suffering from) it seams to be a drive train issue. The vehicle is still moving when he let's off the throttle.

I'm guessing it's drive train but it doesn't seem very consistent. Sometimes are louder than others. I'm going to check the drive shaft again. Or maybe throw a GoPro under the body to see if I can pinpoint anything.

I first thought exhaust manifold when you said whistle, but watching the vid it's more a squeak or chirp I would say.
If drive shaft is greased, I would look at wheel bearings, although I have no experience of them with discos. Jack each corner and see if you have any odd wobble.
I've just replaced my guide pins in the calipers which cured a squeak I had. Kinda similar to your noise. Cheap, easy and another thing to tick off as 'done that'. I can almost imagine a slightly warped disc/rotor making that cheep noise, if the pins were bad. Any vibration with braking?
