[GMCnet] Ball Joint Stud Torque [message #81919]

I torqued the upper ball joint stud nut according to the GMC Manual X-7725,
page #A-22 and stripped the threads. It list 100-125 Ft. Lbs. for the upper
and 40-60 Ft. Lbs. for the lower. Are these numbers reversed. After a
closer look I realized that the lower ball joint stud is larger than than
the top. Makes no sense to me that the torque spec for the lower ball joint
stud would be less for a larger stud.

Anybody know what the correct torque for the studs should be?

I just looked at the manual. In my manual, on page 3A-22 it shows
that the upper is 40-60 ft pounds and the lower is 100-125 ft pounds.
Did you just read it wrong?

Emery,

I read it again, and it is just like I stated. Just what I thought. The
numbers in my manual are reversed.

What I had looked up was the page 3a-22 in manual X7525.
When I looked it up in X7725 it was reversed and just what you said.

It looks like GM screwed up in the X7725 manual.
