Circling back to this photo because my phone battery died, and I continued work until my wife re-charged it for me.
In any case, there are some things to do before removing the carrier:
1: Mark both carrier bearing caps, not only for location, but for orentation. They MUST be installed in the same place, and in the same direction upon reassembly.
2: When finally removing the carrier, it is likely that the shims on either side of the carrier will come out with the assembly, as well as the carrier bearing races. KEEP TRACK OF WHICH SIDE GOES WHERE. If you're not starting from scratch, and using a used gearset, you'll need these in the correct location in order to keep backlash where it needs to be.
3: When changing gear ratios, the pinion gear must also be changed. I have no photos of this process, but it is fairly simple--remove the pinion nut and flange. If the carrier is removed, the pinion gear will fall out the back, so be careful.
Now is a good time to replace bearings and races. The pinion races can be driven out with a punch from the opposite side fairly easily--no special tools are required here. Just a hammer and a good punch. Keep the old races so you can drive the new ones back into place without beating on the new races.
If you have the strength of a gorilla, feel free to use a new crush sleeve. I, however, use the one that was originally in the differential housing that came with the departing gearset. The variable here is not usually the gears, but the variance in the housing. If you're going to re-use the crush sleeve, match housing to sleeve. Do the same with the shims for the carrier.
