No, it is not a major job. Before you put the pumpkin in the car, take the rear cover off and clean out inside there with some brake-cleaner. First remove the S-spring in the center of the diff. Next, find the 8mm bolt that goes through the diff which holds a metal bar in the diff between the spider gears. Remove that bolt and slide the bar out of the diff. Now you can rotate the spider gears so that the ones that had the bar going through them can come out. Remove them, and then the side gears can be removed one at a time by sliding them into the center of the diff and pulling it out. Once that is done, the clutches and steels will just slide right out. Stack the new ones in place and put everything back in reverse order. The only tricky part is getting the spider gears back in because if they are one tooth off, the bar won't line up again. That might take a few tries to get it right, but the rest of it is pretty straightforward. Oh yeah, the other part that sucks is getting that spring back in there, but a big channel locks and a friend should be enough to get it back in there. Either that or a press if you have one.
