Tools Required

1. Slowly turn the J 33792 clockwise until the right differential adjuster nut sleeve contacts the differential case bearing.
2. Install the J 42213 to the left differential adjuster nut sleeve.
3. Slowly turn the J 42213 clockwise until the left differential adjuster nut sleeve contacts the differential case bearing.
4. Mark the location of the adjuster nut sleeves in relation to the carrier halves.

Ensure that the notches in the adjusting sleeves can be counted when turned.

5. Using the J 33792 , turn the right differential adjuster nut sleeve out two notches.
6. Using the J 42213 , turn the left differential adjuster nut sleeve in 1 notch.
7. Rotate the pinion several times in order to seat the bearings.

1. Install the J 34047 , the J 25025-1 , and the J 8001 as shown.
2. Place the indicator stem at the heel of a tooth.
3. Move the case through the case's free play while holding the pinion flange.
4. Record the dial indicator reading.

Specification
The backlash between the ring gear and the drive pinion should be between 0.08-0.25 mm (0.003-0.010 in) with a preferred specification of 0.13-0.18 mm (0.005-0.007 in).

Important: When adjusting the backlash, observe the following:

•	Always turn the left and the right differential adjuster nut sleeves in equal amounts.

•	Turning the differential adjuster nut sleeves one notch will change the backlash about 0.08 mm (0.003 in).

•	Once the proper backlash is obtained, turn the left differential adjuster nut sleeve in one additional notch in order to preload the differential case side bearings.

5. If the backlash is too small, use the following procedure to adjust:

5.1.	Increase the backlash by turning the left differential adjuster nut sleeve in 1 notch and the right differential adjuster nut sleeve out 1 notch.

5.2.	Recheck the backlash and adjust as necessary.

6. If the backlash is too large, use the following procedure to adjust:

6.1.	Decrease the backlash by turning the right differential adjuster nut sleeve in 1 notch and the left differential adjuster nut sleeve out 1 notch.

6.2.	Recheck the backlash and adjust as necessary.

7. Once the proper backlash is obtained, turn the left differential adjuster nut sleeve in 1 additional notch using the J 42213 in order to preload the differential case side bearings.
8. Recheck the backlash and adjust as necessary.
9. Perform a gear tooth contact pattern check. Refer to Gear Tooth Contact Pattern Inspection .
