If you are like me and are a DIY'er and found yourself on this posting trying to figure out how to do this Job.
Then did it. Here's the 10K foot view on how to replace the rear hubs & bearing without removing the axel at the diff in photos.
In summary, pull the hub with a slide hammer & applying heat on the bearing with a torch is highly advised. Then get to slide hammering. Trust in the process. -sometime later.
Once the Hub is out, press the bearing out. There a many videos on this process. This is the tool I used:

Now unbolt the upper to rear control arms and rear toe link. Articulate the wheel knuckle downward and pull out the axle.
Carry on with the repair. Repeat on both sides for peace of mind.
