I have a 1977 f100 2wd shortbed with a Dana 44. I am thinking about putting a locker in it. I need to know how many splines the axles have. I was hoping someone knows or knows how to tell without removing the cover. Any advice?

 

didn't that come with a 9"?

 

There were'nt many truck that rolled off the floor with a Dana 44 in the rear, but they do exist (I've been told it was just 77 and 78 when this occurred?). I'd prefer a 9", but my 77 has a Dana 44 as well. I'll look around and see if I can find out what spline axles it has.

 

My luck. If there is an oddball out there, leave it to me to find it. I'm sure it's a 44. I just wasn't sure of the splines. I wish it was a 9".

 

You'll need the Bill of Material (BOM) numbers off the axle to verify but page 74 of this document states that it is 30 splines. Tab down in the left menu for the Ford rear D44 axle.

Enjoy.

EDIT: The hyperlink above contains a code for that dang smiley and I can't get rid of it. Nonetheless, the link will take you where ya need to go.

 

Thanks. That was exactly the kind of info I was looking for.

 

All of the following Dana 44.3 rear axleshafts have 30 splines. All are right/left specific.

The following axleshaft part numbers depend on what the Ford AXLE ID tag code is.

The tag is under one of the bolts that retains the inspection cover to the housing, but...many are missing today.

D7TZ-4234-A Right & D7TZ-4234-B Left .. Axleshafts

D8TZ-4234-B Right & D8TZ-4234-C Left .. Axleshafts.
