In response to DD74Chevy
That is DRAG TORQUE. It is measured on the torque wrench bar by the pointer on the torque wrench AS THE PINION IS BEING ROTATED BY THE TORQUE WRENCH IN A FULL, CONTINUOUS ROTATIONAL CIRCLE.
In other words, put the inch pound torque wrench on the pinion nut, with the carrier and ring gear OUT of the housing, and continuously spin the torque wrench and pinion, while reading the scale. If the drag is too low, tighten the pinion nut a small bit, and do the drag test again. When you arrive at the scale specification, stop, the pinion nut is tight enough to sustain the correct pinion bearing drag specification.
This operation is one of the reasons my inch pound torque wrench doesn't have a hand holder on its pull end, it has a ring, so a finger can be inserted in the ring, to spin the wrench all the way around in a circle, evenly.
Simple as that.
