Have you ever had one of these trans axles apart ?

MODERN and PRECISION are not the hallmarks found in a Peerless® trans axle. :) The only thing approaching modern was the use of Torrington® roller bearings.Everything else about these units, right down to the machining quality and the choice of other materials used screams CHEAP!
Flushing these units out with the solvent of your choice is not going to cause injury to it. If it fails after flushing, it's because the destruction started long before you drained it.

When changing trannie oil its a good idea to flush the case [with
kerosene] prior to refilling. 
    

Probably 35-40 years ago, an old-timer recommended this to me for manual 
transmissions and even crankcases in ICE cars.  

But then about 25 years ago I read an admonition to NEVER operate any 
lubricated machine without proper lubrication, not even for a few seconds.  
I don't recall where I read this, but IIRC the gist of it was that 
"flushing" with a non-lubricating solvent may have been OK for old, loose-
tolerance gears and bearings, but was not such a good idea for modern ones.

So, if I were going to "flush" my ET's transaxle, I might do so with a cheap 
and/or light grade of gear oil rather than kero, discarding the "flush fill" 
after a short period of light-load operation, and replacing it with the good 
stuff.
