lower ball joint- 75 ft lbs
upper preload sleeve-50 ft lbs
upper ball joints-100 ft lbs
if you have a pull scale the knuckle should take 25 ft lbs to pull
this is from CTeunuch on here who posted in my 44 build for spindle nuts setting the preload on the spindle bearings:
The 'rule of thumb' I go by is tighten the inner nut to 150-200 ft/lbs while turning the hub, back off a half turn(don't turn it while it's loose), tighten to 50 ft/lbs, then back off a quarter turn. If the little locking ring doesn't line up exactly always go LOOSER with the nut a little bit to line it up. If you overtighten them the bearings with cook on the highway. Then you tighten the outer nut to 150-175 ft/lbs.
