and I am a DIY'er. Some people were able to built the tool but, I bought the tool. You do not have to remove anything but, you have to support the differential while you work on the bushings. By the way, there are 3 bushings. Two in the rear and one on top of the differential. Due to the limited room to work with, "conventional tools" will not work...If you are interested in renting the tool from me, let me know...I will give you the details on the rental. Since I recently moved, I just have to look for it. As far as directions how to do it. It is simple, remove the bushings while supporting the differential and install the new ones. I did not replace the one on top but, you have to loosen it in order to reach the rear ones. That is it...

Good luck!
