What's the difference in the axle shaft's diameter between these two?
I'm swapping in a stock HP D44 in place of my built stock D44 and I'm wondering if I'm going to be in good shape for a while with the stock axles in the new HP???:confused:

thanks

No difference in size.

30 spline 1.31" diameter for all stock Dana 44s (may be some exceptions in REALLY old trucks, like 60s and older)

the U-joint is usually the weak link and can be of different sizes, the main ones being 260x joints, and 297x joints (recently replaced by the 760x) I *think* EBs all came with the weaker 260x joints.

Also the stock axleshafts had thicker steel around the ears.

Thanks for the clarification guys - I was under the impression they were a little more HD than the narrow track 44's.

are you talking about front or rear axles? HP only came in the front. Narrow track usually refers to a CJ rear. Cj rear axles (except the 86) have smaller axles (1.27 I think) then most common 44's.

no it's a front - I just said widetrack vs narrow track to clarify between the HP and the Stock D44 out of my Bronco.
