Aside from pulling an axle out, is there anyway to tell a 28 spline ford
9" from a 31? Was going to get my daughter a detroit for Xmas, since she has
sent back the 2nd lockright, we've given up on them, but I don't know how to
tell 28 from 31, and it's pretty hard to say, Do you mind if I keep your
jeep for a while so I can pull out an axle? And still keep it a suprise.
When I pulled this rear end out of a car with my brother-in-law, he said
it was a 31 spline, but when he redid gears for us, he didn't use the 3rd
member from the thunderbird we took it out of, he used one from a van, so
now I'm not sure if any of it, including 31 spline axles are still there, or
if those got swapped too.

 

I don't think you can tell from the outside. If the 3rd Member is from a
van, I'd expect it to be the stouter 31-spline type. But, that's just a
guess ...

The assumption I use in making that guess is that the van will have a
heavier payload than the Tbird, therefore a stronger axle. If you remember
the year of the van, you may be able to dial in on the spline count from a
parts manual.

Don't know anything about the Econoline it came out of, 69 T bird housing
and 78 econoline 3rd member.

"early half ton trucks got the 28 spline axles and carriers, while
sometime in the early 70’s the switch was made to mostly 31 spline axles
and carriers for most trucks" :

http://www.gearheadracing.com/Refere...FordDiffer.htm

Almost certainly a 31 spline, but there's only one way to know for sure.
