it also has the 4x4 locking hubsin that link ,, sounds like you need a new one or both since they should slide out in tact
OBS is not the same as the superduty. The superduty has the break away style rotor you are speaking of. The obs does not.
To remove the rotor, remove the hub lock cap, then remove the inner part of the hub lock. It should be held in with a snap-ring of sorts. Under that you should find a double nut with a pinned spacer in between. You need to spin off the first nut, then remove the spacer and then spin the second nut off. The your hub should be able to be pulled off. Then to separate the rotor from the hub you will have to pound out all 8 wheel studs. I would recommend re-packing the bearings as long as you have the hub off. When you go back together be careful not to over tighten your wheel bearings. And MAKE SURE YOUR KEYED WASHER IS ENGAGED PROPERLY ON THE INNER NUT. If it is not you will have issues. When I started working on trucks like this I would lay out the parts from the hub out on a bench in the exact order I took them out to ensure I got them back in in the correct order. And I highly recommend only doing one side at a time. That way if you absolutely can't figure out how it goes back together you can disassemble the other side and compare to it.
I hope this helps you.
