SnowTrac Axle - P/N ST 2054, spline wear

I am going through the ST4 I bought this fall and in disassembly/inspection have discovered that the splines (circled in red in the attached photo) on the right side axle of my machine are fairly worn. This is based on the slop I can observe between the hub (part # ST 7681, item #39 in the diagram) and the axle itself (part # ST 2054, item #36 in the diagram). If I put the right side hub on the left axle it is a much tighter fit and what I would expect with a splined axle & hub.

This leaves me with a few questions:

1) Have any of you experienced similar issues?
2) Does anyone have dimensions for a new axle?
3) Does anyone have a take off axle they would be interested in selling?
4) Without digging deeper the root cause could be in the hub so does anyone have a hub (ST 7681) for sale too?

Thank you ahead of time and thank you to Lydon for sharing the parts manuals.
