Banjo Axle Question - Where There’s Wear

[JM 35 Sedan]

It's tough to give an accurate opinion based on viewing pictures on a small cell phone screen, but here's my opinion:
The rust pitting on center axle would need to be cleaned up, or you could consider relocating the lip seal a bit axially, so the lip rides on a different area of the axle.

I would also be concerned about the keyways, tapers, and threads on those, or any axles you plan to use on your rebuilds. I would suggest having those areas carefully checked before attempting any assembly.
