changing upper and lower ball joints on my 2003 blazer xtreme. Does anybody know the correct torque spec? Seen video and said 17ftlbs but look online and see these specs.

Chevy Blazer Lower Arm Ball Joint Torque Spec : 79 ft-lbs

Chevy Blazer Upper Arm Ball Joint Torque Spec : 61 ft-lbs

Are these correct?

 

I've never worried about the torque on ball joint, providing we are talking about the ball joint itself, as in the castle nut and not the four bolts that hold the ball joint to a a-arms. I just tighten up the castle nut snuggly, the back the castle nut off until I can slide the cotter pin through the hole in the stud. If you go by a set torque setting only, odds are you will have to back off or tighten the castle nut to align the hole. I'd rather back off a bit rather than tighten a bit. Call it my preference but I haven't had any problems doing this way over the last few decades.
