The wheel hub assemblies front and back are different but are relative. The back doesn't have an axle going into it and is held in place by four bolts.
My experience so far is the backs are easier than the front of a higher milage car as the axle up front can be difficult to get to break free.
You'll need to:
Remove the wheel
Remove the brake caliper and hang it on the spring (and not by the brake line)
Remove the rotor
Disconnect the brake/sensor connector
You'll see four bolts in a square around the assembly, those are it.
