I picked up a set of Unimog axles on the weekend, with some 40 inch tall military tires. For those that dot know what I'm talking about, a Unimog 404 axle is a 1.5 ton live axle with portal boxes to increase ground clearance by 6.5 inches and 7.56 gear ratios to boot. I was going to resell them for profit but my dad(theist person on earth to bastardized a vehicle) said I should put them under a van. Good idea dad.

I would need either a suby or preferably a diesel, inthe back, connected to a rear wheel drive transmission, connected to a transfercase, and then driveshaft to the front and rear axle. Since the centre part of the diffs are interchangeable I think, I might be able to swap 3rd members front to back and have proper direction forward if need be to open up my engine choices.

The only drawback will be that it would be a rear engines front wheel drive van, unless I find an Awd transfercase to make it work

I was thinking of a built Suzuki samurai transfercase, that handle v6power and 40 inch tires but would spin backwards with a vw setup and probably have oiling issues

Does the driveshaft of a synchro van spin the same direction as a standard truck?

It gets to be a real PITA to fit a tire much bigger than 30" on a vanagon. That should be your first consideration.

Seems like the portal axles from a T1 would make for some interesting variants, since you could use all manner of transaxle options

I know, my old syncro had really small tires. But with live axles I can go higher, all I'm loosing is my low centre of gravity

How do the diesel syncro conversions work, does the transmission change engine rotation direction?

The problem is that you will hit the fenders(even by cutting them off), the battery box, suspension and the door. You will have to give the van a massive lift really affecting the COG and making a a poor wheeler.
Do a search for syncroghia's build thread to get a better idea of what i am describing.

Anything is possible with money, time and skills.

That is exactly what you should do. or put them under a 4wd with a frame and all. I don't know what your skills are or the tools you have but that would be a very large undertaking and even the most talented guy would struggle to end up with good results.

Of course people said this about the Splitzgauer and I am doing it anyway. So go for it and prove us all wrong...

What about the steering? That will be a PITA too.

I like the Splitzgauer concept. I'd do the whole Mog chassis and graft a Vanagon Westy body onto it.
