I have replaced a front flex disk and I never want to do it again. I did it with no lift or hoist and it was a poor idea. Very difficult to get leverage and space to work. Must pull the rear section of the drive shaft and the center bearing and support to really get at it very well. That is why it is the likely choice to do both flex disks and the center bearig and support at the same time. The rear disk is the one most likey to go bad and is easiest to change, not too bad. the front is a different story, not fun, and not easy. If you can stomach it, have a shop do it for you, I dont like paying them either, but it is not a fun job at all and like usual, I was not even satisfied with myself when I was done, it was just a pain. Sorry no better guidance
