Not too hard, this is how i did it:
Jack front end up and get the wheels off, undo both track rod ends and disconnect, then get under the dash inside the car and undo bolt and bracket connecting it to the wheel, undo 3 torx bolts on the rack and it should then wiggle free.. Depending on if you have PAS or not you need to drain that first obviously then disconnect the pipes at the rack.
Hope that helps a bit.. Think the torx bits are either t50 or t55 for the rack
