19. Install the old washer and the lock nut.
20. Using a Nm (inch-pound) torque wrench, rotate the pinion. The torque must read as specified.
To increase the preload, remove drive pinion bearing preload shims. To decrease the preload, add shims.
21. If the pinion bearing preload is within specification, and the pinion position shim has changed, change the drive pinion bearing preload shims by
the same amount.
The direction arrow pointing toward the pinion flange indicates that by removing the drive pinion position shim, the distance from the centerline of
the tubes to the pinion backface increases, giving a plus (+) reading. The drive pinion bearing preload shim pack does not affect the pinion depth
setting. However, if the pinion position is changed, the pinion preload will change and may require adjustment to bring the torque-to-rotate within
specification. Arrows on the ring gear illustrate the method to increase or decrease backlash and differential bearing preload.
