The rod ends have to come off.

The drag link is swung around and cable tied to the spring to hold it out the way

Plenty of room now.

CV joint seals removed.

Note the pitting of the CV joint ball caused by gravel roads(most likely South Aust army service)

Top and bottom two bolts for CV joint bearing pins removed and brake pipe disconnected.
The whole thing is just sitting there.

The cv is now exposed and now can be removed.

Note the seal that will need to come out and be replaced.
This seal separates the CV oil from the diff oil.

The next thing needed is a dial guage indicator.

Set up the magnetic base of the indicator on the diff housing to hold it in place so you can read the backlash between the crown wheel and pinion.

Rock the crown wheel backwards and forwards just a little bit and measure the play between the gears.
In this case the backlash is 4 to 5 thousands of a inch.

The next step is to bearing blue the ring gear and check how the diff gearmesh has been going.
The idea being that when the locker is fitted we try to achieve 4 to 5 thou backlash and the same gearmesh pattern.
I will have to get some bearing blue from work .

The parts taken off the vehicle are laid out is so I know which side of the vehicle they came .
