The 15mm bolts holding the hub to the spindle. One broke because I lost my grip on the torque wrench and it slid off of the head slightly. Just too much pressure for that cheapo socket. The other two were craftsman and they broke when I was torquing them down. I think the tolerances between the hole size in the new hub and the ohm lots were just too close. Those two broke just as the wrench clicked.

Oh, I forgot to mention that I broke the end off a 1/2-drive, 5" extension within 5 minutes of starting this project. That was on the right front hub to axle nut.
Don't get me wrong, I love my truck. But the first owner was in Pennsylvania. Never again will I buy a truck that came from the North. Corrosion on every single fastener.
