Ok I have it as Such:
After looking in The WS Man(Can be Confusing to make sure you are getting the right spec for the Right Model) and Chatting to Nissan and a Couple of Mechanics this seems to be the consensus:

Lubricants for a Y61 4500 GRX

Engine: 10w40
Gearbox: 75w90 GL4
Front Diff: 75w90 GL5
Rear Diff: LS Diff Oil
Transfer Box: ATF

I am thinking of Going With Liqui Moly on all the replacement oils, has anyone used this and what were your experiences?

What do you Guys Rekon? :think:
Your input will be much apreciated.

Rob, do you really have a limited slip diff and not a diff lock?

There were some models with LSD, but I have never seen a LWB 4.5 with LSD instead of diff lock?

Also, WRT the transfer box, check wether what's in there is normal gear oil or ATF (smell) and replace with whatever was in there before.

You have raised the 2 that I was Concerned about.
Mine has a Diff Lock so I don't know why Nissan would recommend the LSD oil? My common sense tells me GL5 would be the Right way to go in the Back Diff as well :think:
As Far as the transfer box goes that's a good idea will take some out tonight and Check whats What..

Rear diff uses the same oil as the front.

Check what you have, but transfer case should have ATF in it. On the Y61s with the automatic hub locks, there can be issues with other oils than ATF in the transfer case (when cold, the viscous drag slowly rotates the front prop shaft, thus causing the autohubs to partially engage with a crunch at speed).
