No special tools:
It's easy to press the bushing into this 2" piece of PVC with a vise because it opens up as the bushing goes in - with a little help from a screwdriver.
The second side is pushed in, till the bushing is centered, using a socket.
When both sides of the bushing are in, I use a hose clamp with help from the vise to squish (tm) it closed tight.
Make sure not to pinch the edges of the bushing - I used a screwdriver to push the bulging edge in as I went.
When the hose clamp is closed it should look like this:
Then I made another tool like the first, only 1.25" long, to go around the inside of the control arm's hole flange.
Place into the arbor press (I'm sure a vise would work...) and push hard keeping everything centered.
Did I say "Yippee" yet?
