They are self-adjusting but often benefit from a manual adjustment. Some cars, but not this one, have an opening in the back of the backing plate that allow adjustment. Without one, you just have to pull the drum off, adjust, and check for tolerance. If you can't get the drum back on, the shoes are too tight. Once you can, push the drum firmly against the hub and turn it back and forth. It's OK if you hear a slight scraping noise as long as you don't feel any friction or resistance. For it to be loud enough to hear while driving, it's probably too tight, or something else with the hardware is out of whack.
