Differentials
Can you guys help me confirm which differentials are on my truck?
It is a 2020 F350 CCSB, 4x4, 7.3 gas, NON-Tremor. Currently has 3.73 gears from factory.
I am 99.9% sure it has a Dana 60 front and a Sterling 10.5 rear.
The front has Dana stamping and numbers on the cover, but no obvious identifier. The rear has Ford cast into the housing, but no other identifiers.
The diff shop is having trouble trying to figure out what is on it without looking at it. Makes me think about using a different shop.
I would take it down to them so they could have a look, but they are 1.5 hours away.
Thanks

The Dana has a fill plug on the cover that the Sterling doesn’t have. That’s an easier giveaway then counting bolts.

There are probably 20 threads going back to 2017 that show pictures comparing the two. Once you know what to look for spotting the difference is easy.

Should be a Sterling, mine is. '22 F350 7.3 3.73
I wouldn't be upset with the shop, they probably do not just do axles on Fords... Look how much trouble it is to get a straight answer here...

I have 3.73. I am pretty sure only the 4.30s get the Dana. There is no drain plug on the rear, just the fill on the side of the housing.
The front has a drain plug on the cover.
The diff shop thought the front might be a M275, never heard that before.
Thanks for the help, I think philips nailed it

M275 is the Dana rear axle. The front may be called a 265 now but it has been the same axle for at least a decade so they kind of, should have known the front axle for sure. I understand the rear being in question.

Too EZ to just take a peek n see for one’s self and determine which one has.
Shop doesn’t know difference……..find a different shop.
