I bought a set of used Alloy USA Chrome Moly Axle Shafts from craigslist this weekend. I've torn them down and cleaned them up with the purpose of putting in new joints and putting them in the Jeep. After cleaning them and removing the old joints, I have my doubts that they are actually Chrome Moly. Does anyone know of a way to identify Chrome Moly short of a hardness test?

Its hard to tell easily. A metallurgical test by a professional would be the for sure way. Are the shafts machined for full circle clips? Do they back down in diameter? Any physical markings on them?

How about a picture?

what benzie said. I've seen some shafts actually labeled 4130 (which is chromoly)... but I'm sure not all are stamped/labeled.

Just got home and snapped a couple pics.
The ujoint size seems to be the same as stock. Spicer 1310 or 5-760x / Moog 371/377 based on my measurements.
Some markings on one of the outer stub shafts read FOAX456V & 2004510E. None of the rest have anything stamped or cast into them.
Regardless. I only paid $150 for them and also got 4 Rockkrawler extended braided brake lines and a Dana 30 master rebuild kit with them.

The shafts do neck down as well. I'm thinking they are stock. I'll google the casting number to see if there's any info on the web.

Maybe chromo inners? Coloring looks like aftermarket. Some aftermarket shafts do neck down. Stubs may be OEM. There's a lot of casting numbers on them, I can't for see the aftermarket spending that much time adding casting numbers.

As mentioned above the first thing to look at is whether the ears are machined out to accept full circle snap rings or just c-clips. Stock shafts just used c-clips and most, if not all, aftermarket chromoly shafts I have seen use the full circle snap rings.

For the taper, tried to take a quick look at the pictures of these shafts on the Alloy USA website but pretty hard to tell for sure. The tapering by the u-joint ears looks different (doesn't look like any tapering in this location on the website), but there does appear to be tapering out towards the axle splines.....but again it's hard to tell and always the chance the company has gone through different iterations of the shafts.

Thanks everyone. I've decided that these are not Chrome Moly. But, no great loss, the other items I picked up, plus having spares were worth the $150 buck.
