Looks like Oberaigner offers lockers as well as gearing modifications. They say the ESP stays functional and is only briefly disabled when locking.

^^ Good luck getting any of that stateside. There was someone on this board at one point who had tried to get Oberaigner to agree to modify his USDM sprinter and they wouldn't touch it even if he shipped it. I think they are worried about homologation requirements, though I am not sure why. Im sure you could get them to mod a van, but you might have to tell them a couple white lies about where the van will end up.

I also seen some Facebook posts where 4x4 owners are having problems either getting into or out of 4x4.
There are horror stories abound of whitefeather conversions having serious problems. They stick a solid axle under the front and I think the ensuing problems with the electronics give people fits.

My 2008 with oberaigner 4x4 conversion has their central diff lock... as for getting them stateside, the previous owner spent a year pestering them with emails before they agreed to do the work and that was back in 2009... i doubt they would go through that again now that we have 4x4’s in the US

I can't see why a rear locker would interfere with the ESP/ASR if used in low speeds (as you would with a locker). Both rear wheels would be moving exactly the same so no slip would be detected... unless the steering angle is accounted for, in which case it might give fits if it expects one of the wheels to be 'off' in rotation with regard with the opposing wheel.

We could possibly disable the ESP/ASR with the illusive 'dyno mode', but it would be best to be able to just hit the air locker for the rear and climb out of the sand/mud/rocks, then unlock...

We would still need to overcome the fact that Inglhaut (who makes a rear locker diff) won't even reply to emails from the USA (at least mine).

I've got a Whitefeather 4x4 Conversion and you definitely don't want to go with one of Craig Jackson's conversions. It has taken me years to repair the work he has done.
The guy is a real hack.
Here's a photo of the newest problem I've had to take care of.

This is the high pressure side of the power steering hose and how he adapted it to fit the Mercedes power steering pump to his steering box. It rubbed against the power steering pulley and the ABS controller causing 2 leaks. The hose had also rubbed against the AC line which ruined it, a $500 part plus a recharge.

Default Converting to 4x4, has anyone?

Uni-Van is doing Ford Superduty Dana 60 front and Sterling 10.5 rear 4x4 conversions. They are in florida. Using Atlas transfer case. Heard he was working on some coding but it was driving around. Id prefer those axles with unlocking hubs and factory electric lockers offered. Parts are easily sourced.

Hi there

Iíve had contact with Igllhaut, Obereigner and Achleitner. All 3 the responses are basically, ship your van to them, pay the circa 20000 plus Euros and they will convert it. In the case of Obereigner it needs to be a brand new van, not used. They wonít just do a locker. They will not sell parts, fullstop, even wonít sell an entire rear axle with locker in it at any over priced huge margin. I even tried getting parts at a price that includes their fitting labour and profit, but no go.

If you want locked rear, itís probably easier to do a axle swap and chop and weld with something like G Wagon or Dana 60 to put the sprinter ends on. Donít plan on diff ratio swap on the 4x4# either because of that front diff you wonít be able to, let alone the Merc electronics complexity.

Cheers
