This happened to me too

he he... oops! I didn't want people to know this... but to help a fellow Fitfreaker I guess it is worth it.
Anyway, I wrestled with it for hours and was convinced I screwed it up for good. I finally managed to get it back in my lifting the whole assembly up much much higher that I was before and ensuring it was prefectly straight. The best position is to straddle brace it with your both your knee's, lift it up and push in and out softly while twisting slowly (sound like something else I like to do!).
Don't Cut the Rubber!! Just cut the banding!!!
I also removed the boot and re-packed the joint. I used hose clamps on the boot until I got a banding kit, if you do this you need to ensure the clamp screws are opposite of eachother so you can minimize the eccentric weight until you get it fixed.
