yep, pop the bearing cap. There's either a cotter pin and a retaining clip and a big nut under it, or theres just a nut with one side pinched. Remove it either way, and the drum should pop off with the bearing. Slide out the drum a little, push it back in and pull the bearing out first. Remove the drum.

Make sure you keep everything clean, wipe off the bearings and repack them with grease. I usually replace the rear dust seal at the same time.
