I have a lot of tools-more than most, but less than a lot of you. I did not have a transmission jack, but I do now. Right before I got ready to go on vacation I decided to drop the Dana 18 / T-90 combination out of my jeep. I put a floor jack under the combo where I thought it would balance, instructed my son to get back a little and to lower the jack slowly once I had pulled the assy back far enough for the input shaft to clear. I pulled the assy back rolling the jack along with it. As it cleared the bellhousing the weight all shifted and it started to roll off the jack. I had my hands strategically positioned so that if something did go wrong, I was safe. I had my left hand over the top of the cross member. I had my right hand on the top of the drum brake on the back of the transfer. As the unit came off the jack, I watched in slow motion horror as the drum rotated around so that my index finger on my right hand would be perfectly positioned directly under the drum just as it hit the floor. It was, and the unit hit hard and bounced. I crawled out from under the jeep and said "I hope its not broke". My son said what, the transfer case? I said no, my finger. He didn't know it had gotten me cause I didn't so much as let out a peep, I jut grabbed it and wrapped it in a rag. It wasn't broken; I didn't go to the doc; and we left on Vacation on schedule. I was lucky-but it is still sore and doesn't bend quite as far as it used to!
