Does anyone know if the brake rotors on my '88 F150 4x4 are seperate from the hub, or do I have to remove the auto hubs to get them off?

I am starting to get ready to do a 4-wheel brake job and that is the only question I have left to be answered.

Any info or advice is appriciated.

P.S. I am not replacing the autohubs at this time, so If they have to come off, they will go back on too. The haynes manual does a good juob explaining the steps to do the brake job, but lack the info on what years the rotors were intergrated with the hubs.

Thanks in advance.
