8 3/4” carrier bearing preload

The backlash setting is used to preload or stretch the third member to minimize ring and pinion deflection during acceleration and coast. I’ve never seen a torque setting, only the technique to set the ring gear side of the pinion at .001 or less backlash, and then adjusting the pinion side adjuster to achieve proper backlash on the gear set. The pinion side adjuster preloads/stretches the case the set amount required to achieve the backlash setting.
