Looks like all SD's now coming in front with what most of (on 17+ SD section of FTE) think is the D50 used in the rear of Braptor,
at least the diff casing size and R & P. Might grab a set, or at least a front, before the world figures it out and prices start
going up.

Didnt all dxx (d25-70) start being referd to as mm2- - as in the millimeter diam of the ring gear?

Old SD axle was a Dana Super 60 or M256 (256mm about 10" ring gear), or so I'm told.
My only SD experience (axle or otherwise) is the NEW 23 F250 CCLB HO 6.7 I just picked up.
But diff casing (top to bottom) is only about 11" vs 12"-12.25 ish for D60.

2023 F-250 Front Axle - Dana M256? - Ford Truck Enthusiasts Forums

2017+ Super Duty - 2023 F-250 Front Axle - Dana M256? - Just picked up a 2023 F-250 4x4 Lariat Ultimate 7.3L FX4 3.73-elocker. According to the Ford spec guide the standard front axle for the 23 F250 4x4 is a Dana M256. Most of the pics of the M256 I have seen show a 10 bolt diff cover. My front...

Never priced one, just assumed they have been around so long, they were not too bad.
Maybe I'll just grab more mog spares then.
 
Agreed.

From post 26 in that thread:

Looks like the new axle is the Dana M235 (50) Advantek in reverse spiral (high pinion) flavor.

It's the same ring gear diameter as found in the new Bronco rear end.

It is a downgrade from the 2017-22 M256, I had a chance to see a new 2024 SD and the pinion nut and yoke is much smaller than the previous gen.

The tube and knuckle size is the same as the Dana M256 though.

One plus is the ground clearance is better. But I'll take beefier over clearance all day long.

Oh, and you can put the aluminum cover from the Bronco Raptor on it.

Most claim the 23's ride a bit better than the 22 SD's, so a lighter front axle may have some to do with that.
Shame they don't offer a "snow fighter" package like they did on 79ish F250's, so they got the D60 front, and
keep the M256 as an option.
 
As long as the outer package stayed the same, I don't really care.

But good to know.
 
Looks like a lot of speculation in that thread based off oil fill plug location and number of bolts on diff cover

This was also posted. I don’t know the source but seems to verify it’s a 60 not a 50. Maybe there’s just some variations from prior years like we’ve seen before

Should be pretty easy to ID, since it has a different diff cover

Other info in that thread seems to point at the 10" D60 ring gear not fitting inside it, with it more likely having a smaller gear set like the D50. That would seem likely since the pinion nut got smaller.

Who cares how a wonton rides unloaded?

Whatever, will probably be 20 years before I have to buy one of that vintage. Current newest F-3shitty is a 97.
 
Is it on all of the new trucks or just the single rear wheel or lighter duty stuff?

Interesting, the "Super 60" was always overkill for your normal F250/350 but all of us liked the overkill.

In 2000, sure.

With the power and weight they have these days the Super 60 seems appropriate.

Everyone in the off road world always forgets how much punishment a modern truck in low range on pavement can dish out even if it only has the leverage of a 31-33" tire.

I measured diff casing height. it's significantly smaller than the 79 D60 rear casing in my 79 Bronc.

23 F250 CCLB HO 6.7


D50??? 11.25" ish

79 D60 12" + (rear diff, and it might be light, as tape measure was not exactly at top of diff case)

Doesn't bother me much, as long as axle tubes, hub bearings and such are up to the task.
Feel bad for the Tremor guys who might wheel one of these. I only use 4WD in muddy lots
towing my junk in or out. I don't even use it in winter, so it doesn't get the salt.

For fuck's sake, stop referring to the new Advantek axles by legacy names that have nothing to do with the Advantek axles other than rough size equivalency. This all started with Jeep's retarded marketing department when the JLs came out :shaking:

That's disappointing to hear the Dana 60 is getting replaced by the M235. I wonder if it is just the 250s or the 350s too? Sorry, I didn't read the FTE link. I guess Ford looked over at the Dodge's AAM 9.25" and decided they could drop down to a 9.25" ring gear as well. Should still be significantly stronger than the '99-04 Dana 50 in every way though, and probably pretty comparable to the newer 1555 AAM 9.25 axles.

Don't hold your breath. These are the same fucking idiots who refer to three visibly different axles that have less parts and specification commonality than the D60/70/80 family as a 14-bolt because they have the same number of bolts on the covers.

With what trucks are rated for today vs 05 I really doubt ford put an inferior front axle in them. Who knows , maybe in 10 years this will be the one to build for your mega bouncer on 59" sxs

I forget the exact details but somewhere in the S110/130/135/150 family of axles there's one axle that's equal smaller in every way than the one above it but also equal or stronger in every way because they used fancy steel for the housing and threw every trick in the book at the center section because they were trying to reduce weight, not build a weaker axle.

Someone had a write up about it. Might have been here or the old site or one of the diesel sites.

I'll call it whatever it actually is, once someone figures it out.
So far it's under every configuration, 250/350, dually, 7.3's, 6.7's etc...
Not sure if anyone checked Tremor's yet.

Well it sure as shit isn't a Dana 50. What does the sticker on your axle tube say? If a Bronco Raptor diff cover fits, I would say that is a pretty good indicator that it is an M235.

Even Spicer still refers to them by the legacy names. Mainly because the legacy names are the weight rating for the axles.

D30 = 3,000lb
D44 = 4400lb
D60 = 6K lb.
Etc.

you forget about the variable thickness tube in the rear axles in 2020-2021? That would collapse and had a recall?
