Live axle skilz

[Gridgway]

In my new to me crossflow which I am fettling over the winter I'm wondering about the Ital axle.

The car has done 9,500 miles since new and everything looks to be in good condition, but I don't know if everything was new when the car was built.

I have some questions about the axle.  Is there anything obvious to see/know about with regard to wear?  Anything that wears quickly and what if anything I might check.

Then are there any strengthening upgrades to apply?  Also is there a go to specialist for axles?

Cheers
