Thanks for the encouraging words. I am sure that you guys are speaking from experience. All I can say is maybe my bolts / wheels / hubs are trying to make me crazy.

Although not a NIS calibrated torque wrench, I am sure that it is not grossly inaccurate, threads are AOK (thread bolts in by hand till they seat), then torque to 80 foot pounds (factory specs say 110 newton meters == 82 foot pounds).

The bolts all have broken in the extension area. It seems like they bind up in the ball to wheel seat area. Everything looks good and the bolts have broken on different wheels.

As far as factory bolts, gee at $7-8 each ...

Oh well!
