Lars, I did mine with the axle still in the car. I removed the 4 bolts that attach the pivot point, one side at a time. I kept a floor jack under the trailing arm I had loose to prevent it from dropping too low, as well as having the car on jack stands. The hardest part for me was after using threaded rod and a variety of washers and pipes to pull the old bushing out was removing the sleeve that was part of the old bushing left in the axle tube. I couldn't find anything the right diameter to press it out, so I used a hack saw blade to cut the length of it. That allowed me to get under the edge of it to fold it and remove. The same combo or threaded rod and bits I used to press out the center of the old bushing allowed me to press the new one in.
