There's not much room to get behind the CV joint. It is possible with a large tyre lever or thin chisel. If you can get a thin chisel in, then tap the end with a hammer, rather than levering. Tapping will pop the C ring so the shaft can be withdrawn. How's the support bearing in the box? The normal reason for the seal to leak is the bearing allowing the CV to move sideways.
Is that support bearing replaceable as easily as the seal is?

Not the gearbox side. The box casing needs to be split so it can be pressed out.
The IRD side is easier, as the IRD end plate can be removed to get the bearing out.
