I would drop the rear first.
Unhook the driveshaft, four nuts.
Six bolts, two nuts and two axles for the rear.
Once the rear is out carefully sazall out the two bushings outer sleeves using two cuts about 1/2" apart so that you can peel out the bushing.
Then as Young Tom says use a big a$$ bolt nut and washers, lots of grease to press in the new bushings.
Or combine that with the cro-magnon method of a metal plate and a four pound dead blow hammer.
Can you do it without dropping the rear.
Could be, but you would spend much more time and effort, using laser scalpels and or Dremels, and stuff that most shops do not have.
