the rear bearing is not replaced like the front. It comes as a complete unit with new wheel studs and hub assembly. They do not come separately ever.
It is actually bolted on to the trailing arm, in the same place if its disc or drum, the only difference is that the disc trailing has a bracket for the the caliper. pretty simple to replace in fact.
This is what they look like out of the box. hub and bearing as one for the rear. This set has the abs centric ring on it but same thing part numbers are even the same between disc and drum if I remember correctly.
