Poor Little Cone Style

Well, I do enjoy a good argument from time to time. So using your thought process, if the breakaway spec is 150-300 FT LBS, how do you check that? Think about it..... You CANT test it while having engine torque applied to it, so what exactly provides this torque resistance your measuring?????? the SPRING pack!!!!

Yes, you CAN check it. I used to do several a month at the Ford dealer. Since they are torque sensing, they will ramp up from the drive shaft flange, OR either axle. There are tools specifically designed to measure the breakaway torque. It is essentially a large torque wrench. The one we used at the Ford dealer was electronic. It senses when the clutches or cones break loose and registers that inertia as breakaway torque. Some of the aftermarket units like the Dana Power Lock and the Pro series Auburn can see close to 1000 LB FT.
