The difficulty of changing the upper bushings is not as bad as some make it out to be. Drill out the rubber, crush the side of the bushing in and then just pop it out. The drilling and crushing are critical. To speed things up use the biggest drill bit that will fit between the outside of the bushing and the sleeve. If you attempt to press them out you will get nowhere fast. The last time I did a set it probably took less than 30 minutes. I found a dull chisel to be the best tool for crushing the side in. This is what the last one I pulled out looked like after removing it.
