OK, here's what I have regarding ball joint torque values--this is NOT from FSM, but from the Dana/Spicer info that comes with the ACDelco parts I use.
1. Torque to 65 ft/lb
2. Locate cotter pin hole in stud then continue to tighten until slot in nut lines up with hole
3. DO NOT BACK OFF NUT WHEN LOCATING COTTER PIN HOLE
1. Torque value varies by size, though minimally
9/16" 75-85 ft/lb
5/8" 80-85 ft/lb
2. Follow same procedure as for upper ball joint
