I bent a rear axle flange, and was donated a JL Rubi shaft as a temporary replacement. To my surprise, there were a few differences between the JT and JL shafts. First, the JT shaft has a snap ring just inside the bearing retainer, which the JL shaft (and most other D44s) doesn’t have. Second, the JT shaft is tapered differently, being thicker through the middle part of the shaft. Other than these two differences, they seem dimensionally identical. My shaft does show some spline twist...

Thanks for posting the pics! I've done gear jobs on both models, but never at the same time so I could compare.

I did note the obvious diameter difference between the two and figured it was done to minimize bending due to the probable higher axle weight rating of the JT axle?
