Front or back? The fronts have a screw that holds them to the hub. Use an impact wrench to get the screw out. Most are rusted and a PITA to remove. Front will come off after the adjuster is turned loose. The hub stays in place. Rear? Full floating axle type. Pull the axle and the drum can be removed with the bearing. Messy and requires a wrench to remove properly. Not too different from a 3/4 Chevy. Keep the drum and brake shoes for reference. There are different size drum and shoe combinations. Some have a bigger diameter, and some are wider. You need to measure so you know what parts you will need. Parts including the seals are easy to find at your FLAPS. Enjoy. 4x4 will have different fronts than 2 wheel drive.
