Pinion nut torque can be used as a final adjustment on preload and turning torque. This applies to solid spacers as well as crush sleeves, which should not be used in a performance application.
How is the preload affected by torque when the yoke bottoms on the pinion shoulder? Once the yoke bottoms on the pinion shoulder, further tightening won't preload the bearings any more...you can keep tightening the nut until the threads fail and the bearing preload will stay the same.
Not on those pinion shafts with crush sleeves
Cab, what they are saying is with a "shimmed" non-crush sleeve application, once bottomed, tightening the nut more will have no affect on pre load.
However applying more torque to the nut WITH A CRUSH sleeve will add more pre load to the bearings. As the yoke would not be bottomed on pinion and tightening the nut more will add more preload as the sleeve crushes more.
I'm sure you know this
but are likely misinterpreting what they are saying
.
