: What's the spline diameter on Ford 9" 31-spline shafts?

Anyone know?
I'm hoping I can squeeze it through a D44 spindle, which is 1-5/16" at the torrington (inner) bearing.

TIA,
Chris

1.325 on my spare 31 spline shaft

Aargh... that's just over 1.313 (1-5/16"). Probably won't quite fit through the D44 spindle bearing. It'll be a pain having to remove the spindle and everything else, just to get the shaft out, but not the end of the world I guess.

Thanks for the info!

are you making a full floater rear? if yes then most people who do that remove the needle bearings from the spindle so it fits. Some people bore out the spindles a bit too because if the housing isn't perfectly straight the shafts may rub.
