NEED HELP on how to remove obs rotors with warn locking hubs

[Mzarlenga]

So I got my new rotors today. Me and my dad went to put them on and we cant figure out how to take the old rotor off. Before we mess around with anything, I need to know the steps of removing the old rotor. And do you have to take off the locking hub assembly in order to take the rotor off? Someone please help! Thanks a lot,

Mike

i thought most lock out front ends had a large king style nut, to remove the hub, after removing the allen screws that hold the selector knob, you may have a snap ring, and a king nut, which uses a special socket, then the whole hub removes...bearings and all.

Yea we tried removing the hub. We took out the six allen screws and pulled off the top of the hub, and then springs and bearings came flying out so we just put them back in and put the top of the hub back on and called it a day. Do you have to take the hub off in order to remove the rotor?

no just the caliper and the rotor is retained by the lug nuts ,, it may need a few taps
click that link i posted it has a brake job
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.
