2014 E350 SMB 4x4 build differentials

[Petravic]

I've got a (new to us) 2013 Ford E350 with a 2014 SMB 4x4 build (see attached). Based on the build sheet, it's got the "standard" 4WD build with none of the options. I'd like to understand what differentials are in the front and rear axles.

I'm assuming the rear axle is the stock Dana 60 - if so, is it an Open or LSD?

The front axle is a Dynatrac Pro Rock 60 - what's the differential that went into the standard build?

Thanks!

Do you have the binder/build sheet from SMB? You can also contact Field Van (formerly SMB West) with the original owners name and they can usually supply you with lots of build info via email.

Rear axle - check the axle code on the Drivers B pillar build sticker for the axle code. You can then look that up with an online search. That will tell you ratio and LSD/Open. This will at least tell you what it left the factory with.

You will have to pull the rear center cap to see if you have a Full Float or Semi Float, only way.

Front axle - post a picture or two here and someone will tell you what you have. See if you can find a tab with numbers.

thx! had already sent a query to field van and still hoping for a reply. the van is out at wasatch getting a refit this month but i'll follow up on your other suggestions when we get it back. really helpful.

I mean there's an easy way - just jack up the axle and spin the wheel. See if both turn in the same direction, or of one turns the opposite direction.

Ask Aidan to snap a pic of the sticker on the driver door w the axle code.
If the refit includes rear axle tire off, he can very easily tell you if the rear is full or semi.

Petravic - Where are you located?
