Suit Nissan Navara Thai and Spanish D40.
This is the rear diff Pinion Nut that is located in the center of the rear diff flange. These can be very hard to undo and often lead to the nuts edges getting rounded.
If this happens to you, you should replace it as once you do it up again you may never get it back off.
This Nut is for the Rear Diff only.
