Hub on 2WD SS vehicles has a filler shaft?

[the roadie]

A 2WD SS owner was posting in another forum about changing his hubs out. And he posted pics of his old ones showing a stub shaft filling the center of the hub with a 35mm nut securing it. In the non-SS world, 2WD vehicles have that splined center of the hub open. You just bolt the replacement hub up.

Anybody know about this stub shaft? I'm just curious, and I never knew this tidbit about the SS before. Could it be for airflow management around the brakes? I can't imagine it being structural. Was it on only some years? Every 2WD SS have them? :confused:

I would have to see a picture to know what you are speaking of. I do not believe that mine has any type of filler shaft at all.

Here's what the member posted. New hub on the left. Old one on the right, and the filler in the center was not part of a broken-off CV shaft. And I'm asking in an SS forum, so the question is really for the 2WD SS owners like he was.

I would have to double check mine, but I do believe mine has it as well, don't know when it will be though
