I've been doing this for years with the exception that it can be done on the vehicle. Spray the bushings down with penetrating fluid. With the vehicle on A lift lower the vehicle slightly onto a jack stand to relieve pressure on the control arm and zap out the bushing as shown. Install new bushing in reverse with a mushroom bit for the air hammer. This does not work on all suspensions but will on many and very fast.
I use a MAC long throw for everything. I've used short throws as well before and they worked too. Some of the heavier barreled bushings may need the long throw though.
It's clear that you don't have to deal with road salt and rust. You cannot remove our control arm bushings this way, and you leave insertion of new bushings completely untouched. Why not use one unified technique for removal and insertion?.
