A press is the easiest, but if not that, a long grade 8 bolt,nut, and a bunch of big thick washers can do the install. Torch works well for removal.
Insert bolt with a couple of washers through bushing and arm. Add more washers and nut. Start cranking on the nut/bolt. Watch you don't collapse the arm.
