Fitting of a front automatic locker into a GU Nissan Patrol.
I forgot to mention, the bearing caps in the carrier need to be torqued to 93-103 nM.
Sorry about the whispering, the mrs was asleep while recording 
FAQ’s:
-My patrol doesn’t handle any differently on the street in 2wd after fitting.
-When turning (offroad), the locker will click as the teeth on the locker pass each other. This is normal. You can barely hear it on my car.
- The locker cost about AU$400. It was a ‘Spartan’ brand locker. Bang for buck its the best traction mod you can do aside from a good set of tyres. total cost was about AU$500 after buying oil, paper and liquid gaskets etc.
Essential tools:
Torque wrench
1/2 inch ratchet and sockets up to 7/8 and 19mm & extension bars
Long punch or an old philips head screwdriver (for pushing out the cross shaft securing pin)
C clip pliers
Screw drivers
8mm allen key
Cable ties
Long nose and regular pliers
Hammer
Locktite (permanent strength)
A new diff gasket
A tube of liquid gasket
Jack stands & a capable jack
5.4 Litres of 85w/90 Diff oil (NON-lsd). Oil comes in a 4L bottle so using 1.4L of your old oil is ok if the oil is still good.
