It looks like you might be asking about a few different torque specs so I'll address all of them separately.
For a trailer axle spindle nut like part # 165686 you will need to run the spindle nut down until there is no more side-to-side play in the hub and then back it off to the next notch so you can secure the cotter pin, like part # 165649, through the spindle.
When it comes to hanger bolts like the Redline # 166081 there isn't a specific torque rating either as you just need to make sure that the knurls on the bolt (lines by the head) aren't showing. If you get suspension bolts too tight then it will keep your suspension from moving like it needs to.
Finally, if you're referring to lug nuts for your 225/75R15 tires then you can see on the attached list that if you have steel wheels then the lug nuts need to be torqued in the range of 90-120 ft-lbs but if you have aluminum the range changes to 90-100 ft-lbs.
