Review on Edelmann 80338 Power Steering Pressure by Carlos Deuschle

Power steering no longer leaks. It wasn't too bad to replace. The trick is that you don't have to remove anything apart from the drive wheel and you can take off from below, but turn the wheel all the way to the right so that the control hand is not in the way. The tool used was a wrench with a flare of 16mm from the bottom and 18mm from the top of the hydraulic booster. Installation took about an hour.
