can you show me pics in how to change my rear rotor on my dually?

the rear rotors are fall off rotors. what that means is you remove the wheels, remove the caliper and the caliper mount and then the rotor will come off. you may need a good size hammer to break it free but it slides off the hub assembly.

do you have to remove the axle to get hub off ?

no, you do not. the rotor slides off the hub assembly.
