plain bearing types can be removed by tapping and screwing a bolt in then pulling on that
you need a real tight fit for the grease trick
if you have a slide hammer it is possible to make a steped pin/top hat shape to hook onto the bearing then wedge it in the hole by packing somthing down the side of it
other ways is to weld somthing to it and pull on that
got some taperd races out once buy welding a bead around the inside letting it cool and it shrinks it and just pulled it out by hand
