Either way makes no difference, the axle is shouldered and there are no
retaining devices for the bearings, just press fits.  But it will usually
finish off the bearing. Your biggest problem is making sure your new
(28mm?) bearing lands are absolutely concentric with the drum. I made a
special pot jig for this.
