I am trying to change out a leaky side/output seal...Finally got the cv shaft separated from the axle stub.A friend told me i should be able to pry the stub out easily..Not so much.Moves in and out about 3/8 of an inch but it sounds really solid on the outer edge.Do i need to line anything up?...pound it out with a hammer?...use slide hammer only?....just don't want to do more damage!..read somewhere here it shouldn't be this hard....
