This is what i did in order not to get oil all over the frame and the garage floor not to mention my arm.
First i cut a piece of cardboard like this one here, but not this once, i used this one for illustration purposes
Then inserted between the hose running from the steering pump and the 2 hard lines in the steering shaft.
So it should look like this
Then make sure you pull towards and past the filter so that it will catch everything falling from filter once you remove it.
Dont forget to place your oil pan under the cardboard to catch the oil
