I just did this two weeks ago. First, remove the drop links entirely.
then...
1. Boil them to soften them up a little bit. Put them in a coffee mug full of hot water... carry out to car.
2. Smear some moly grease on the bushing and the drop link.
3. Force the bushing in... I pressed with a C-clamp. It started the bushing in.
4. You may need a screwdriver to "help it along"... encouraging the part of the bushing that doesn't want to go in.
All in all... less than 30 minutes for four bushings. That included when I put one in backwards... had to pop it out and press it in from the other side of the link.
I agonized over this, too.... but it really is easy.
