How Does One Inspect Half Shafts For Condition, On Bench If Necessary?

[gapi]

I have 140+k miles on the OE half shafts and Hubs. Everything is quiet and smooth. A recent drive shaft and couplers.

I'm going to be under there in coming weeks swapping out the open 3.06 Diff with another of the same converted to Wavetrac LSD.
I can checkout the hubs no problem but have no experience with CV axles. This is my 1st independent rear suspension. The diff will be out so I could just pull them and have a look. Not sure how to inspect while installed other then the obvious.

I want to know how to really inspect them for signs of wearing. Or...............

The other part of me says, over 140k miles, a Supercharger added @128k dynos' 459, and going to LSD, just change em now? I would be going MOPAR OE R/T axles and SKS hubs.

Prepping, waiting ring gear bearings and the Wavetrac.

No one?

The halfshafts are only serviceable (rebuilt) by those who do it for a living. As such, there are not replacement parts outside of boots (which even then require the skillsets to R&R).

If they are serviceable, produce no noise, keep using them.

Note that replacing parts that are in good / serviceable condition - just because one has the system disassembled - is questionable at best...

Thanks, I have no experience with them so I had to ask.
