Having trouble finding torque specs

[eurosport22]

I got a 3.73 diff used. I wanted to replace the seals and o rings and such as well as just thoroughly inspect the unit. Im having trouple finding the spec for torque on the sode carrier flanges that hold the carrier bearing races. Only thing i have found is 22nm or 16 ft lbs. that seems a bit low but im not sure. Can anyone confirm the spec on them as well as the rear cover. This shows 45nm or 33 ft lbs. im just having trouble thinking the rear cover should be tighter than the carrier flange. Thanks in advance

And i guess as a side ? Do i really need to replace the bolts like ive seen? I wouldnt think 8.8 bolts would fatigue but again, this is my first time disassembling a e30 diff
