R32 Gtr Rear Diff Noise

[Aussie GTR]

I was just wanting some help diagnosing an ear piercing noise that is come from what sounds to be the rear diff. I sounds like high pitch humming that seems to almost disappear when I'm going 100km/h on the highway, but between 40 - 80 km/h it is almost deafening. Can someone please throw some ideas at me? thanks

Have you taken your rear seats out at all. If it sounds like bees flying right around your head, it is probably your fuel pump. I may be totaly wrong though
