When I bought my TJ, I was told it had chromoly axels. I've pulled them out and didn't see any stickers or markings. I know at least one has been replaced because I found leftover carnage in the diff housing. Any way to tell which, if any, are chromoly?

well, I haven't dealt much with the chromolly axles and don't know if they're marked differently, but as a melter in a foundry if take it into work and spark it in a spectrograph. I guarantee you wont find one at an auto parts store, ours is a $200,000 machine.

If the outside of the hub flange, the part that shows through a wheel hub opening, is plain without some kind of a manufacturer's logo on it, I doubt it is chromolly. Manufacturers of high-zoot alloy/chromolly axle shafts are proud of their stuff and tend to put their logos on the hub so it can be seen when the wheel is mounted.

That's very true. But sometimes that glued-on medallion doesn't even survive the act of pressing the bearings onto the shaft.

I will almost bet good money that the pieces are from a chrome-molly axle due to the way they shattered and the complete axle isn't due to it having rolled splines similar to factory.

Purely a guess, educated, but still a guess.
