My land rover with the original 4 speed gearbox and transferbox whines when in fourth going anything over 35 mph and when I let off the accelerator it stops, it also gets much quieter when I have a full car of people?! Is this normal
 
How do you hear it? Though the floor, or window or somewhere else? What happens if you do 35 in 3rd? My first thought is take the plate off the top of the transfer case and check the mainshaft nut is tight.
 
Oil level correct?
I reckon you are worrying over nothing, series and noises go hand in hand.
 
With series box's I found some were quiet, some moaners and some whiners. As long as the have good oil they keep going. Internal rattles not good.

There is not much to no whine if I do 35 in 3rd and I will check the nut. Cheers
 
Check it again, and the transfer box, if seal on main output leaks the gearbox level goes down and transfer overfills.

I have just went to see how tight the main shaft nut was and the locking tabs weren't even in place and I could push it with a screwdriver it was that loose, how tight should it be?
