I wasn't using a torque wrench. It didn't call for any torque specs in any of the install instructions that I saw. I don't have a torque wrench that would fit in the small space anyway.
But that's the thing. I wasn't giving them hell I was just snugging them up normally when it snapped. It could have been cross threaded. I had problems with that one from the start, kept cross threading. I thought I finally had it right though when I drove it on in.
It might have been damaged previousely, or bent, it got real tight halfway on, still had some to go when it snapped...I admit, I may have overdone it, I was frustrated by this point, but it seemed to have sapped under less torque than I applied to all the others. It didn't really snap, it just slowly twisted off.
