Drop the oil in the diff probably full of water.

Definetly put new oil in it but it sounds like the damage has been done.
It might last but it will be forever noisy.
Put some decent diff breathers on while your doing it.

grease up your uni joints on the drive shafts

if that doesn't fix it . get a stethascope (spelling) and put it on the hubs, diff center ... i'll more accurately pin point the problem

see if you can wobble the drive shaft up and down or side to side, if the pinion bearings have given way, then the crown and pinion will no longer be meshing correctly, and that will make them noisy

Not being a smart arse but is the rear drum brake ?

Is clean the brakes.

It can some times make the same sound.

Have also had strange noises after immersion with Hilux drums - mud and grit everywhere.....
( usual disclaimers )

It seemed like a much better idea when I started it than it does now.
