18. If the pinion bearing preload is within specification and the pinion position is changed, change the drive pinion bearing adjustment shim by the
same amount.
-
The direction pointing toward the rear axle universal joint flange indicates that by removing shims the distance from the centerline of the tubes
to the pinion back face is increased, giving a plus (+) reading. The differential 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-rotation within specification. Arrows on the ring gear illustrate the method to increase or decrease backlash and differential bearing
preload.
19. With the drive pinion at the correct preload as determined earlier in this procedure, remove the pinion nut and the drive pinion nut locking washer.
20. Coat the pinion seal with grease and install the pinion seal.
