The left hand side one is easy, just undo the top ball joint pinch bolt, undo the clip that retains the ABS sensor cable to give it some slack, and undo and remove the brake caliper , then you can just pop the upper ball joint, let the whole spindle plate pivot outwards on the bottom ball joint and pop the CV shaft free of the diff with a pry bar. Warning mine was VERY tight. The RHS is a different story, you can remove the CV shaft using a similar procedure but if you want to remove the diff centre then you will also have to remove the straight axle shaft extension from the spline inside the diff. You will probably have to unbolt the extension housing from the diff housing, and piull it off as an assenbly with the axle inside.
Are you sure the actuator is gone? It is a lot of work to do if it turns out to be just a failed pump or split or blocked air tube.
