Hi,

I have a 2013 E-350, and I'm trying to figure out what rear axle I have. I know I ordered it with 4.10 gears and a limited slip. Now I want to upgrade that to a locker.

How can I confirm exactly what axle I have? I've had people tell me it's a Dana 60 and others say it's a Dana 70. I see 248 stamped into the axle, 05, and 2014828 with a B under it.

Any help is appreciated

 

Dana 60 full floating most likely, look for "60" cast into the web near the diff.

 

Check the door jamb sticker and see what is listed under AXLE then compare to this list. AXLE CODES
