Dana 44 long side axle lengths

Boonie Buster · Apr 29, 2008

I am trying to find the long side axle lengths for a Fullsize jeep, and a few different year/style wagoneers, etc. I am trying to find a stock axle length to shorten my long side to, to get it to about 64" WMS to WMS I am using a ford inner short side, chevy outers(not critical info for shortening axle....unless someone suggests otherwise...:eeek: )

I found a website that show what axle to use to get it to a certain WMS to WMS using a fullwidth chevy Dana 44, but the Ford HP dana 44 i have is slightly shorter...making the numbers off

From what i have measured first hand the the ford HP D44 I have is just over (barely)1" shorter than the fullwidth chevy D44. This is from my physical measurements, and info found on drivetrainoutlet, under their AlloyUSA axle info. (just took the numbers and subracted the difference...)

So does anyone have these axle shafts handy to measure or know of a place that shows that info???:corn:

I've used this chart many times in the past:

http://www.warn.com/truck/axles/inner_axle_app.shtml

Lengths of the more common inner axle shafts helps you play mix and match. Outers do matter. You'll notice that 1/2T Chevy D44's and 3/4T use the same shafts, but the 3/4T axle is 2" wider (69" vs 67"). Scout outers are 1" narrower than Chevy 1/2T. So it maters.

What you trying to build? I have a passenger side drop, 62" wide (depending on the outers you uses), HP D44 I built a while ago sitting in storage. Scout II long, Dodge Short (comes with (2) spare short shafts).

For the right price, it can find a new home.

I am trying for 64"-65".

So how is it that the outers play a part in wheelbase? I am using ford outer spindles with 5x5.5" rotors, so do i have to use ford outers then? I was thinking it possible (for some reason i had the idea in my head) that i could use the chevy outers on it.:eeek:

MAN, so now i am really confused

I have a jumble up mess...

So here is what i have to use:

I have ford spindles and rotors, 5x5.5" B.P.
3/4 ton Ford HP Dana 44 to be narrowed to 64-65" WMS to WMS.
I am keeping the short side axle stock length and shortening the long side to a stock axle length (TBD) somwhere around the 64-65" range...

From what i had measured the ford and chevy rotors were the same distance away from the upper BJ center. Unless someone can tell me otherwise PLEASE do so:corn:

Basically, what method do you go about shortneing an axle... because apparently I am missing a few dimensions in my thoughts

:booo:

Basically I jsut gather up the total length of all the axles (inner and outer) for both the chevy and ford axles and subtracted the difference.

I figured, take the amount out of the inner axle on the long to make it to the WMS to WMS would be enough, then cut the axle tube down that length...:corn: since the outers wern't changing length...

Thats the way I would approach it.

What is your over all width using the housing and outers you have (if they work the same as Chevy, the base housings and shafts should be the same, difference in width is made up in the hubs). So you find the width your at, compare that with the width you want (for argument lets say your at 67") look at the length of the long side you have. Compare that to the chart and find a compatible shaft that is 2-3" shorter.

*assuming* your stock long is 33.91, and your start width is 67" a pre '80 waggy would shave you down 1.79", so 65.21" wide, or your looking at custom or something thats not on the chart (Dodge?)

ya, I have measured and the ford axle with ford outers WAS 68". I though about putting the outers i plan to run on it and see if there is any difference, which i doubt because it is interchangable and the point where the outers u-joint center is, should be the same for chevy or ford...otherwise neither would work and destroy u-joints by just turning, thats why i was saying i didnt think they were critical to figure out my WMS to WMS,:eeek: .

the longside ford axle shaft is 34.75" long, so if i could find something to match that, and even if i had to cut down the short side too that is no problem (ie find another short side axle slightly shorter....) that is fine, because i am breaking both sides "C"s loose to rotate the pinion accordingly...

So maybe that is what i need to do...find one for each side to get a someone closer width, and then cut the tube down that amount (difference between current and desired axle shaft lengths...:eeek: ) Right?
