I worked out an easy way of getting the OEM hubs apart and back together. First shot I removed the small spring locking washer when the entire hub components were in the hub. Cleaned it up and had a hell of a time putting it all back together whilst trying to compress the large spring down and hold the top plate down. I needed four hands... I remove the other hub and turned it upside down, with the gears facing towards the bench and gave it a good tap and the entire locking section came out in one piece. So there was no need to pull it apart like I did...
I almost bought some AVM hubs but I don't like the idea of those small screws in the cap as last time two were jammed in so bad, I went through four torx bits before I gave up and just broke the thing off. Maybe if they had some never seize of the tapered section of the screw it would have been a different story...

Note. I had already removed the plate that makes these hubs auto a while ago, so now they are just full manual hubs...
