Thanks for the help. I have a service manual but they are not any good for this job. I found the slots. I was looking on the driver's side and that one is well concealed and also tight for space. It helps to remove the caliper assembly for that side. Right side is quick and easy. I still have a problem. The adjuster for the left side won't move. According to service manual you are supposed to lift up on adjusting tool. Can somebody confirm this? Also is there a special adjusting tool for this application? I modified the tool I had but I still can't get the adjuster to move. I have tried both ways. Ryan, when looking at the set up on the dually the rotor looks like it is a part of the whole hub assembly which would involve pulling the axle and taking off bearing retaining nut and pulling the whole thing. I may be wrong but that is how I see it. The manual seems to be for the 1500 rears as the pictures etc. are mostly 5 bolt hubs. Again thanks for the replies. One can usually get some good help here.
