Never mind, I got it.

The trick is to slip the bushing over one of the two lips of the flared section, using a lot of grease, apply pressure in the inward direction (bushing going onto the rod) and then pry around the edge with a long screwdriver.

You'll want a padded glove to be able to exert a lot of force with the pushing hand. You should also use a pair of polycarbonate safety glasses b/c of the screwdriver. I didn't have any eye protection, and when the bushing popped onto the rod, the screwdriver flew free and nearly took out my right cornea. Yikes! Learn from my lack of caution.
