Mitsubishi Canter 4x4 information?!

Hi I have an FG639 1996, the crew cab, with manual gear box and push button 2H/4H and 4H/4L. A 4D34 is under the seat!

I am having trouble getting information on any model of 4x4 let alone my 1996 model.

I have a chassis manual for a 1990 with some bits being the same.

I need to replace the front wheel bearings and my 4H/4L low range switch is not working!

To disassemble the free wheeling hubs I require special tools: the lock nut tool and hub puller. I have looked everywhere and can’t find. The Fuso dealer near me said it was doubtful they could get it and if so expensive. Anyone know where to get these from? Or any work around? Also because the axels and drive line is pretty much the same over all but the newest models does anyone know if the super singles wheels fit?

Also if anyone knows what model transfer case this year has and where I could get diagrams or information to diagnose the low range problem. At the moment I don’t even know how it works, I assume vacuumed assisted switches? There are few up for sail used in vic and I wanted a stick/linkage 4wd system for this very reason!

Because the 4x4 canter is a rare beast there is little information on it. It is essentially a big cab over 60 series cruiser, but when it comes to particulars the info ain’t there! So if anyone can point that would be great. I use it for work at the moment but if it’s ever going to be driving on the beach up north.... thanks.
