I guess all the talk about the Trailing arm Bushings is because they are attached to the Axle. The others can be taken off the car and Pressed out or Beaten out or whatever. You are forced to use finese with the Trailing Arm Bushings.
When I did mine I used Big Sockets to Press them in. I wish I took the time to measure the Diameters so I could find Better fitting Plumbing parts to use for next time.
Here's a trick I used when doing Pressed in Ball-Joints on my 4 wheel drive vehicles. Throw the Bushings in the freezer overnight, the few thousands that they shrink helps a lot.

Those bushings need to be removed and installed with a press. When I did the job, it was much easier to bring the trailing arms to a local shop and have them do the job. They charged about $20 to press in my parts. Same with the front end. Bring the parts in to a machine shop. I used poly bushings for the trailing arms and panhard rod. That's a diy job.
