I got the drive shaft from Tom this week and tried to install it. As intended it is a bit longer than the original shaft. I thought to place it in it is just a matter of pulling the TC back a bit to the back and slide the new front drive shaft in. To do this it seems to be a very complex job. I took out all the bolts that connect the TC to the transmission (e-torx) and the bolts from the rear shaft that connect it to the TC. I thought after pushing the rear shaft back a bit I could take the rubber universal joint/flange out but I couldn't due to the centering sleeve. So, what I see I have to do next is to take the rear shaft out to be able to remove the universal joint. But to do that it looks like I have to take the exhaust pipes out and then the heat shield and the the transfer case support and then move the TC back a bit to make room to install the new front drive shaft it.
Am I missing something here? Was this supposed to be as complicated as I find it. Most likely I am not doing the right thing. PLEASE HELP!!!

BTW, the shaft repair is very well done. Thanks Tom.
