I've done a W201 and a W123 without the pullers. All you need is a combination of punches, screwdrivers, channel locks and maybe the old bolt you have removed. (Along with a hammer.) You aren't trying to save the old bushings. Just try not to bang up the journal the bushings fit in or the other steering components if you haven't removed them.
Don't know about the 126 but I'm pretty sure I could change the bushings without removing the tie rods and drag link on a W201.
