No, there are plenty of variants.Are all outer stub axles the same length? I've got one that was eaten up by the spindle bearing and I'm trying to locate one. I just don't want to get the wrong thing.
True, but he's looking for a stub. On those models, the stubs are the same. There are different legnths between internal and external as mentioned, plus some HD's have a larger u-joint knuckle, and maybe some slight odd-ball varients, but by and large all models of normal, internal tooth hubs are the same legnth. Another issue you may encounter is snap-ring location, and I'm pretty sure you couldn't even guarantee getting that right if you ordered the exact same model. The older style hubs have been obsoleted and the stubs just are not made for them any more. You may need to cut a new groove or use a spacer.Be careful, the F250 and F150 HP Dana 44's for some reason have a different inner long side axle length. My buddy tore up a chromo because the spline engagement was something like 1'' of engagement
