you'll need to pull the axles and carrier bc pinion bearing preload is set properly with just the pinion gear installed in the case. you'll need a tool to hold the yoke while you tighten the pinion nut and you'll need an inch pound wrench to verify the pinion bearing preload. when you pull the carrier make sure to keep the shims on the same side they came off of.

Do you have any good mechanic buddies that could help you out?

Once you pull the cover on the axle you will see what the carrier is. Go to fullsizechevy.com and down load the 10 bolt gear install write-up written by VHATO. It explains EVERYTHING. Also, since you will have the rear apart, just replace the crush sleeve with a new one.
When I tightening the pinion nut I use a pipe wrench to hold the yoke, and a 3/4" drive ratchet on the nut. I then use a bar-type inch-pound torque wrench to check preload.
Download the above mentioned write up and read it.
