I am doing a SAS in my 1988 FSB I have a D44 and I am pretty sure its from a 1979 F-150. I am going to rebuild it but my first question is that I am not sure if it is a Reverse Cut D44, how do I tell. Also how can I tell for sure if its a 79' f-150 D44.

Thanks

 

there will be a series of numbers stamped into the drivers side axle tube near the pumpkin if you get those numbers you can cross referance it. someone has a chart maybe mil1ion or numberdummy

 

You need to get the build of material number from the axle housing to ID it.

 

I think i have seen some of those numbers and when I get home I will get them and post them.

 

Well I found only 1 number on the drivers side axle tube 9135c. I found another on the pumpkin that says either 820072R or 620072R. The is another number on the pumpkin 44-8F I hope someone can make sense of these numbers

Thanks

The 620072R isn't listed in any parts catalog I have. Front axles (1973/89) have numbers that begin with either 60xxxx or 61xxxx, but nothing 62xxxx. (I also checked the rear Dana 6 numbers, nothing there either)


Be careful...Jeep and Nissan both use Dana 44's, as do other car and truck manufacturers.

 

a 1979 Dana 44 would have a 61....... bill of material number.

Is this a rear or front axle ?

 

its a front axle and im pretty sure its a ford my friend pulled it out of an old f-150 though he didnt remember what year model and the steering that it has matches a 1979 f-150 front axle.

 

Also the pumpkin has 072 on the bottom of it in big numbers.

 

Well it appears this axle could have originally been a 79 Bronco front end i dont know if that would change the numbers.

Thanks

 

Nope.
I don't have any listing for a BoM number that starts with 62

The highest is 61.

recheck that 2nd digit

also check these sites.

Here is what Bill and I are looking at.

this is the gospel on Ford axles.




Dana 44 REAR AXLES

 

I found a picture of a guys 79 bronco front end and it looks exactly like mine

I will get some pictures of mine on here soon.




thanks

The 1978/79 Bronco's use 610xxx for front axle ID numbers. While the photo of the Dana 44 posted looks Fordish, it looks almost identical to the Dana 44's used in Nissan Titans, which use 44's front and rear.

 

Usually all high pinion D44s or 60s are reverse rotation, the low pinion axles are standard rotation. It looks like you have a high pinion, so it would be reverse cut.
