Upper ball joint castle nut torque spec?

[TheJuice]

Hi all,

Anyone have the proper torque spec on this? Just noticed my Chiltons shows a pic with a spec of 70-100lb ft, and the section on it (which is for 2WD) mentions 110-140lb. ft., with advancement of nut so cotter pin fits (no backing off nut).

Well according to my haynes book
install lower ball jointstud and tighten to 35 to 40 ftlbs install upper ball joint stud nut and tghten to 85 to 100 ft lbs after this intial trque continue tightining the nut to nearest cotter pin hole.
then tighten the lower ball joint nut to 95 to 110 ft lbs Caution failure to follow this procedure may result in excessive ball joint wear and steering effort

highest setting of my impact gun till it lines up with the hole for the pin. Can't go wrong there.

I should be ok then. drives just fine, I set it at 85lbft and then turned to the next hole, so it's probably about 90.

Damn. I must have looked at the wrong one. I just put mine on with 140 lbs top and bottom. [img]images/graemlins/crybaby.gif[/img]
