REAR FINAL DRIVE
7. If the pulling force is outside the specification, use a thicker or
thinner side bearing adjusting washer to adjust. Refer to DLN-
270, "Inspection and Adjustment".
CAUTION:
Select a side bearing adjust ing washer for right and left
individually.
8. Record the total amount of washer thickness required for the correct side bearing preload torque.
ASSEMBLY
Drive Pinion Assembly
1. Install the drive pinion front and rear bearing outer races using
Tools.
CAUTION:
Do not reuse drive pinion fron t and rear bearing outer race.
2. Select a drive pinion height adjusting washer. Refer to DLN-270, "Inspection and Adjustment"
.
3. Install the selected drive pinion height adjusting washer to the drive pinion. Press the drive pinion rear bearing inner race to it
using Tool.
CAUTION:
 Install the drive pinion hei ght adjusting washer in the
proper direction as shown.
 Do not reuse drive pinion rear bearing inner race. If the pulling force is
less than the specification:
Use a thicker side bear ing adjusting washer.
If the pulling force is gr eater than the specification:
Use a thinner side bear ing adjusting washer.
