I kind of get it, so the wheels are driven by a ring instead of an axle shaft? Sorry for being such a neophyte I'm trying to learn.

If you look at this picture....
You can see that the front axle is about 5" above the center of the wheel.
That is because there is a "portal" hub at each end of the axle (shown in the diagram in the post above) that extends down the 5", which the wheel is then mounted to.
Other vehicles that have portals are Mercedes Unimogs. H1's use portals as well, only in a fully independent suspension design.
That is very cool! One issue I wonder about is the distance between the steering knuckle and the wheel hub flange. It would seem the tire would rquire deep wheel wells in order to make a complete swing lock to lock. Am I missing something here?

That's why the wheels are backspaced 8" (the width of the wheel) that way the pivot point is the same as a conventional axle.

So, these axles are from what type/year of unimog? Is the maint. of these axles is in the same level as doing a birf job or more complicated as far as the axle seals and bearings are concerned? Great work 
. Did you make those drive shaft flange yourself? This is the MOST clean and quick swap I have ever seen. OUTSTANDING!!

They aren't from a Unimog, they are Volvo.
OOps! 
That's what I meant to say, VOLVO. Thanks for the correction. BTW, have you used the stock/custom sway bars or there none? What's your take on that?

Looks awesome!
I can't help but comment on the fact that it looks VERY narrow though. Seems you would want a little less backspacing on the wheels to widen the stance a bit. Maybe it's just an illusion, but the stance looks narrower than stock.

It's about the same, 72" outside of tire to outside of tire. The extra weight of the axles helps keep it firmly planted as you can see here with the Volvo 6x6 I had side angles are no problem.

I updated the build page tonight, it shows the timeline a little better.

I kinda thought that as well Ary. I really love the concept but would definately want some wider tires / larger footprint with that height rig. Course I could probably tip it over no matter what.

Some flex shots...

how does the flex compare to regular axles?

I would thing it's about the same since the suspension was unchanged. I never got to wheel it before the swap. This truck had never been off road.

Some of these guys are hard to please but I am very impressed with the straight foward out of the box engineering you used to make the volvo axles work, not to mention all the measuring you had to do . You are a can do kind of guy very impressive. This kind of thinking usually pushes everyone to the next level, but what do I know, the most off roading I do is turning around on a old farm road to go the other way on a two lane paved highway...
