One very important principle to remember is the amount of force applied to the pin. WE usually fail to get enough force on it. Take for example the roll pins in Bilstein struts. You can bang a drift against that pin all day long with a full sized sledge hammer and not move it. Or you can drive it out with a medium ball pein hammer. The trick is to get the strut itself to not move. There is plenty of flex in the strut, so the pin will not feel the trauma of the hammer unless some sort of anvil-thing is held to the back of the strut.

Same with the old-fashioned method of releasing tapered shafts from tie rod ends. Whack them HARD with a steel hammer. It goes way easier if you hold another hammer against the back of the tie rod end.
