Power steering gear box leaks (pictures)

Not sure what you mean by dropping the steering as you don't need to touch any steering components. You're just removing the steering column from inside the vehicle. You haven't said what your car is but it's as simple as driving out the roll pin on the column coupling at the steering box, disconnecting the column wiring terminal coupling under the dashboard, removing the 3 column bracket bolts at the firewall from inside, removing the column bracket to dash bolts that hold it up and sliding it out through the drivers door. You can leave the steering wheel on it.
I don't think I'm missing anything but someone else will chime in if I am.
A manual would def help you in all aspects and you can download one for free if you want to.
Good luck.
