I should have all you need, let me know if you need something more. Here is direct from the GM dealer service manual:
Anytime you have a "circle of nuts" to tighten (like below axle to flang and the lug nuts) you should do in a "star" pattern. Never do a "circle" pattern. Same with basically any multi-nut tightening situation.
For example using the wheel lug nuts (your's are 140 lb ft. torque):

The "Hub Nut" is what you call the main axle nut, per the manual, ***BE SURE TO GET NEW ONES DO NOT USE THE OLD ONES*** You can get GM original (I did recently) from Rock Auto for $6 each or Amazon or local shop.

Notice
Use only a genuine GM front wheel drive shaft nut. Installation of anything but an OEM front wheel drive shaft nut could cause damage to the vehicle.

View attachment 233248Notice
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
