Look on the bottom of the pumpkin. The Dana 50s have "50" stamped on them. My '94 F250 regular cab, with the 351, and 8600 lb GVW has a Dana 50.

below that: 41582 B

The tag itself: 4 09 VF81A UC
below that: (triagle) 61031(4 or 1) 28 (?)

Anyone know of a source for the IFS codes?
Your Bill of Material # does not match any of the possibilities... look at the drivers side axle housing around the u-bolt area for a 6 digit number starting with a 6 then a dash then 1 or 2 additional numbers. The 4.09 ratio tells me you have a D44 IFS since D50 IFS gearsets are 4.10 ratio!

Thanks for those pics Tom, I'm still using them and putting them to good use!

Not to beat a dead horse or anything, but the more I dig into this truck, the more confused I get. The rear axle, a 10.25" according to all reference material, has the following tag, which is easily read:

2 V111C
4L10 10 2 8L08

I understand this to mean the rear axle has 4.10 gears with a locker, 10.25" ring gear, and made on 12/8/88.

With the rear axle identified, is it reasonable to have 4.10 ratio in the back and what the front tag appears to be 4.09 in the front? Is this close enough not to be of any concern?

I will look for more markings on the front axle tomorrow but as of now it seems I have a straight D44 and not the HD or D50.

4.10 rear and 4.09 front is standard.
the front gears are usually 1 or 2 points off from the rear gears to aid in traction.


if you have a straight axle in it and it is a F250, it was swapped in there, because the F250 came with an IFS front suspension. the F350 came with a dana 60 straight axle.

Blue Rebel has a good reputation on FTE.Blue Rebel has a good reputation on FTE.
^^^ The answer to that all depends on the application. If your F250 had the Dana 44TTB HD, yes, the Dana 50ttb will bolt right to its drop arms. I did it in my F250.

BUT, if your talking about an F150, no, it will not work. The arms are shaped different and in different spots.

Lightbulb 1987 f250 Sterling 10.25" & D44 IFS

I am currently redoing ball joints on my truck. I needed to research which front end I had so I could buy the right spindle nut wrench. After reading the thread, I am one of the lucky owners of a Sterling 10.25 semi-floater and D44 IFS. I was a bit surprised about the D44 with it being a 3/4 ton. I though D44s were mostly on 1/2 tons and broncos. But I learned something new as well. But with it being an 87, it is a lighter duty 3/4 ton. I'm ok with it now because the 97 4-door SRW is coming in a year or two!

You will probably have better luck in the correct forum: Super Duty & Heavy Duty - Ford Truck Enthusiasts Forums

FWIW....My Ford Service Manual does not list Axle Code 11 for your year truck. Are you sure you are reading yours correctly?
