Where did I go wrong?
72 3/4 ton, rear upper shock mount nut (leaf spring). Took the torque spec from this post:

EDIT TO ADD:
Upper shock mount is 7/16-20. Torque specs for that bolt size are about half the spec above. See

EDIT TO ADD:
I completely stripped the upper shock mount stud before I got anywhere near 140ft-lbs. (see attached pic)
Is the GM spec just plain wrong? Should I just be going with the spec-by-bolt-size instead?
Thanks,
Peter
