i don't know 100% about the dodge version of the 11. 5", but on the gm version of the 11. 5" you need to pull the axle, pull the nut retainer, nut & outer bearing before the rotor will come off. . [as seen on tv]
socket number listed in the service manual is #8954. . i don't know who makes mopar's listed specialty tools [sk??] so???

Just did mine a month ago. They come off just like the front do, but mine was all rusted at the hub bore.
glad i am wrong. . next tire rotation, i will try and remove the rotors & calipers and antiseize the snot out of the hub face. .
