Just completed this on the rear passenger side using the Harbor Freight tool, without taking the wheel carrier off, just like you are trying. Choosing the correct size adapter is important. Not only for pulling the inner half out, but for 'pushing' the hub all the way in. I couldn't get my hub all the way, then I discovered I had picked an adapter that interfered with the hub.

The biggest challenge is getting the lower ball joint back in the wheel carrier at re-assembly. It has to be lined up at an odd angle that doesn't make getting it in easy. I have a small portable hydraulic ram that helped in pressing down on that control arm, which made it easier to align the ball joint.
