Not sure it's a good thing when you say you've never seen before. Hopefully I can get to the build sheet under the glove box for more information.If that is a front axle, then they are drive flanges. Honestly have never seen this type before. When you get to taking things apart please post some pictures of them.
I was hoping to put in lock out hubs, but don't think I can now.Well then they are definitely a full time, nonselectable hub. What are you wanting to do with them?
I cleaned up the outside more. Turn out to be lubri maticMost likely you still will be able to put selectable lockouts on it. Take one of the flanges off and post some pictures so we can see what you got there.
