Hi, new here, I have mechanical question, and hoping someone can help, if I am overlooking something.

The truck is 4 wheel drive, the bolt pattern is five lug, and one is broken off on left front.
It has manual locks.
I have removed the six bolts and the manual lock, the snap ring, the part that locks the internal and external splines together, along with its keeper screw, and spring.

This is where the problem starts, the inner spline coupling will not slide out off of the axle spline, and it does not look boogered!
The outer spline, it wiggles a little and with it the small inner spline piece does too, but they won't come out.
I built a little adapter for a slide hammer using two of the #10 bolts.
I did not get over zealous but my adapter started to bend in the middle, nothing still, so I stopped.

Is there something I am not seeing, I don't want to break anything, and want to install a new lug bolt.

Thanks for your reply.
As per the diagram, assembly 1k104, has been removed.
There was a snap ring on the axle that won't allow the sleeve to come out, so I removed it, allowing the lock, then the spring to come out, once that screw was removed.
The lock body and the sleeve seem to start to slide, with a little wiggle present, but it seems the sleeve needs to come out first?
I did not think the rotor slid off like the diagram shows first, but it is behind the hub, I will look again today.
Why I need to get to the hub bearings and remove the hub, rotor, and all.
Mine is a five lug, full axle housing, manual lock in/out, four wheel drive F150, that is not a dually, otherwise I believe my components are same.
The first picture link describes an auto-lock assembly removal.
