GM's engineers really like to complicate things. Here's what they list for the axle nut. For most other small cars, 180 foot-pounds is a very common spec.
First Pass ..................150 Nm (111 lb ft)
Second Pass ............. Loosen the nut 45 degrees
Final Pass ..................250 Nm (185 lb ft)
100 foot-pounds for the lug nuts, which is only slightly higher than what is common.
For anything that isn't listed, use common sense or experience. Strut and shock absorber bolt torque isn't real critical, but in some cases they use "torque-to-yield fasteners. Those peel the threads and are supposed to be replaced any time they're loosened, even though the threads look fine.
Happy to know you understand the importance of torque specs. These charts are from AllData.com. That's one of the sites we use. It is horribly expensive for shops to use every year, but you can buy a subscription for just your car for a year for around $27.00, or for five years, as I recall, for around $45.00.
