Whoa, hold on, you DO NOT have to remove the axles to get the rear drums/rotors off of our trucks from 98 up. The earlier trucks had internal rear brake drums that required you to pull the axles out to get the hub and drum off. On the later model trucks, the drums (or rotors as is your case) are externally mounted and all you have to do is pull of the tire, remove the caliper and pull the rotor off. Now that being said, they tend to rust to the hub, and may require some gentle persuasion BFH to get them off. Now here is the issue. IMHO depending on how many miles are on your truck, it is worth pulling the axles. This way you can repack the wheel bearings and replace the axle seals. It really isn't that bad of a job, and if you dont do it, you risk losing a seal and ruining your new brakes. I tend to go through brakes quite often, about every 25-30 K, so i pull the axles every other time and repack the bearings. just my . 02
