I installed it, but wouldn't do that again without more tools. Reason being that I had to remove the ring gear to remove the center pin from the carrier; that was the only way to get the pin out.
I made index marks on the ring and carrier and for the pinion gear and housing to make sure everything lined back up, but it was still a risky venture without having a dial indicator to measure the runout of the ring gear.
If you know a gear guy that is willing to check the gear setup when you are done with the install, I would say go for it. I spent 4 hours, which is more time than most spend, but that's mainly because of all the headscratching, lack of a vise to hold the 3rd member while I worked, and the frequent, "Oh, sh-t, I hope this works."
