A friend has a FJ40 and while doing an oil change he noticed metal in the old oil, he did say it was whinning for a while, anyway he is trying to sus a place in Sydney to look at it and see what could be the problem and then fix it, trouble is most of the people he has rang want $800 to $1000 to fix it is this reasonable considering the whole car is only worth $2000 complete.

Any help would be much appreciated.

Really depends on how much "metal" was in the oil. If it was only small stuff stuck onto the magnet on the drain plug - I'd be inclinded to forget about a rebuild.

Just replace the oil with good 85w-140 grade - like Shell Spirax - in both the gearbox and transfer case (even fit a recycle hose from the gearbox to t-case filler plug - guarentee the gearbox output shaft seal is faulty) and keep driving.

For only the cost of the oil - it'll still hang together.

Depending on what 40 series it is, your options are to buy a 5 speed, buy a 4 speed, that has been taken out for a 5 speed, or keep renewing the oil (which will prolong the life of the box many times)

I drive a 40 series, and her gearbox/trannie have been whining for some time now. Ive been investigating a rebuilt 5 speed box and trannie, and am now saving the funds. However the 4 speeds are a strong box, and as with the other posts my advice would be to keep the oil clean and wait until your mate finds a tooth come out on the drain plug. As with most old girls she'll whine for a long time before spitting the dummy!

Is it the gearbox or transfer that is whining, as has been said if it is the gearbox it should last for a while with (more) regular oil changes.
If it is the transfer then best to get it looked at as the idler shafts delaminate and then the metal will trash everyting in the transfer making it more expensive as the whole thing apart from the case will have to be replaced.
In extreme cases the bits get big enough to force the gears apart which smashes a hole in the transfer case.
