i saw this sitting in my auto shop class and couldn't figure out what it was i wrote down the part number(s) and looked it up and nothing came up
i took 2 pictures but the other one didn't save for some reason
but the

the part that bolts on had a rubber cap on it if that helps


the numbers that were on there said
26570
4384213 (they were divided like that but had the Chrysler symbol next to it)
ms 3760 A (the six might have been a G"
and then TJ02H5

then it had a logo but couldn't make it out because of the rust
it looked like it said FILLO

 

That would be an 8.25 axle. Found in many cars that had small block V8s and in many of the Dodge Dakota trucks with 4 and 6 cylinder motors.

Without the carrier bearing caps, that axle is useless.
