Manual steering box seal replacement

With most seals, the outer surface is flat with the part numbers on it. If the seal has a spring, that goes on the inside. I've never pulled them without taking the box apart, but, it should be doable with a screw tip slide hammer......like the ones used for pulling small dents out of body panels. You might be able to use a screw driver to pry them out, but, no guarantees from me!
