With the everything out of the rear I started out with the solid pinion spacer and the second thickest shim which measured out the same thickness as the previous crush sleeve. I torqued the pinion nut to around 150 ft/lbs and checked the drag with an inch/lb wrench. It needed to be tighter so I took it apart and went with the next thinnist shim. This gave me the right preload, as far as the pinion depth I already measured everything (bearing centerline/pinion face/thickness/etc) and shimmed it to spec before installing the new bearing. After the pinion was set up I checked it again with my pinion depth gauge to make sure it was exactly where it needed to be. Then I set up the carrier with the right backlash then preload (I used a number of shims to add up the total thickness of the factory shims as a starting point which gave me the right preload, I just had to swap some .010, .015 and .020 shims around to get the right backlash). To do it again shouldn't be a big deal at all, it was just a little confusing at first since I've never done it before.
