1989 convertible
 

I need to replace the right rear wheel bearing but do not have a press. Lots of videos on UTube that basically pound the bearing out (and destroy it) with a hammer and anything near the right size. Does that work or are there other options? Also manual shows a split ring retainer - is it typically reusable or should I replace. If replace any thoughts on where to get one. Mazdatrix does not have any. Thanks
