Nothing is pressed on to anything. The inner axles are retained by c-clips, bearings and seals to the brackets. General order goes Inner Cup->Bracket->Seal>C-clip->Bearing->Clip.

You also cannot disassemble the outer CV joint.

You need to split the inner joint, remove the circlip and pull the inner joint apart. This will allow you to pull the half shaft. Now you can replace the outer boot, put a new boot on the inner joint and reassemble.

Of course, it is a good bit of work. Read read read. Dan's article is a good place to start.
