No an Abody but a Mopar

I was wanting to ask how do you remove the rotor on a 84 w100 4x4 truck. It looks like you have to remove the but to get the rotor off but I cant get it off is there something else holding it o .

You have to remove the lock out hub or the cover if it has full time 4x4, there's an outer retaining ring and a snap ring holding the drive hub in place, after that there will be two big "nuts" that require a special socket to remove ( it can be done with a pair of pliers if they aren't super tight but the socket makes it easier) then the hub and rotor comes off and the rotor is held on by the wheel studs.
