If it's the same one in that picture, it absolutely has locking hubs. They're big, bulky, and made by Selectro. It's not a CAD axle. I see no actuator or sleeve in the axle tube. Also, if (and it does according to the posted picture) it has Selectro hubs, it didn't come out of a 93 model originally. They used internal hubs by that point, to the best of my knowledge. Also, Dodge didn't start using Dana 60 CAD axles until 1994 and it's a completely different axle setup, used a 4 link setup with coil springs, and had unit bearing hubs.
