You installing @MB - need my tap for the diff fitting? Watch out for the location, sure you won't get caught twice?. Sing out if you need it. Is this for front or rear?

That would be awesome again thanks Philstar Mate!
Utes loaded up now and off to the factory to do it down there today
Finally tracked down where I posted last installation booboos on the family wagon here:

What did you do to your Patrol today!

Will kindly have access to a proper press today from the mechanic next to work and I’ll be sure to drill the 1/4” NPT bung further away from the crown this time around

That was a good display and noted that his lockers were the Terrain Tamer that use the new 4 pin design Harrop Eaton ELocker. Been checking these out and they no longer use the cam ramp disc plate with the ball bearings to provide disc plate separation to move the pins to lockup assy. Harrop now use 4 pins in lieu of the ball bearing and at disc plate rotation/engement,the pins force a lug profiled lock plate to engage with the housing. Harrop claim a more positive lock engagement and axle rotational lag of max 1/8 turn in lieu of 1/2 turn experienced with earlier design.

For Info: Posted Harrop Eaton ELocker video of current build/operation

Crikey some of these 35 year old OEM bolts were tight

A quick ‘Boiling Water’ bath expansion for the crown to fit over the new ARB center:




And....this is where I stuffed up last time, make sure to utilise a correct sized press for the bearings!



It’s the tiny air hole area on the journal that needs to be scratch free!!

Loving the photo journey, never seen how these are installed before.

Remembering from last time, found the ARB instructions a little misleading in regards to drilling and tapping the airline into the housing. Fingers crossed this slightly altered location should create a straight line away from the crown leading edge:





Chose to centralise the airline between two upper housing bolts for hopefully easier reinstall also:



Thank you kindly @PeeBee Mate for driving your 1/4 NPT tap all the way out again, appreciated heaps

After 30 yrs of hard yakka, how do teeth look (crown/pinion wear mark / shine) and out of interest did U check backlash with indicator_ nom 0.010"??? is the go not sure there..

[MB]

All looks pretty decent inside John Mate, tis only the front diff though so far less wear expected
Set backlash by feel under mechanics guidance next factory over
