Seems like it should all go together fairly painlessly

Buying parts for Sprinters in Aus is 4 times dearer than the rest of the world, why would you want to do that?

Can't buy 4x4 parts in USA or from Europe/internationally to ship to USA. Apparently, Daimler may have agreements with various suppliers not to send 4x4 parts to USA.

T1N and most NCV3 Sprinters in USA were only two wheel drive and no 4x4 Sprinters until 2015 or so.

Even certain factory tools to fix Sprinters were not made available to American dealers.

Even posters here have not been successful in getting the nice Australian roo bars/bullbars shipped to USA (or at least no postings here so far of any success).

Obviously I would be evaluating cost if I go forward. Wrecked or otherwise undriveable 4x4 T1N could yield reasonably priced parts.

If I were to obtain the parts (used) from Europe, I would have to pay someone else to source them, strip them from the vehicle, and palletize+freight. The labor would be substantial. As I am already in Aus, I can do all that myself. Plus I can personally evaluate the quality, and make sure all the necessary bits are there (bolts and hardware for example).

Obviously spare wear parts would need to be obtained. If I decide to move forward, I will search EPC for the relvant part numbers, and see which ones are not available in the USA. From there I can evaluate the cost.


I just realized I have not confirmed if the ML Tcase turns the right direction for the T1N front diff. That would be a deal breaker!

Here are some more details on the M class Tcase from this site. it appears to be down, so I used the internet archive to find a saved copy.

I have attached them to this post.

After doing some measuring, it looks like the fuel tank will need to be moved back about 6" to clear the Tcase. No mods to the tank itself, but new mounting straps will be needed, and a bracket as well. Extending the fuel lines should be simple.

Definitely adds additional and unwanted work.

Cool idea. How expensive are the 4wd front components in Australia? If you're planning to use the ML transmission, I assume you would swap in the 4wd transmission too? It's not a divorce transfer case like the 4x4 T1N sprinter one is so you would have to put the ML's 4x4 transmission in too.

Also, the ML t-case is clocked up much higher than the Sprinter T-case is so front driveshaft angles may become an issue.

The ML front diff used a Rezeppa style joint at the diff and a standard 1310 CV at the t-case. I eliminated the Rezeppa in favor of a 1310 joint but this was not a straight forward conversion due to the pinion flange on the front diff. The pinion flange on the T1N Sprinter front diff is different and looks like it would be easy to source a 1310 companion flange that bolts up.

The gas tank will definitely need to be moved back and the wiring / plumbing to the tank needs to be extended. We moved the tank back about 12" on the Pita Van. Was pretty straight forward in the grand scheme of things.

By Tcase I mean Trans+case as you mention they are a single unit. I would be curious to know what it takes to put the Tcase section onto a sprinter NAG1 trans. The otuput shaft would be different, and possibly the internal stackup on the output bearing and rearward clutch pack would be different.

The front angle is a bit of a concern, I guess I will have to cross the bridge when/if I come to it. Worst case a CV joint would be required? I have little experience with driveline design unfortunately. U joints are usually required to be in the ~6 degree range?

Do you happen to know what direction the the ML front shaft rotates in forward? Assume viewing the shaft from behind looking forward?

Thanks for the info!
