2. Clean all the gauge parts.
3. Lubricate the outer and inner bearings with axle

lubricant.

4. Place the bearings into the pinion bearing races.
5. Place the inner oil slinger onto the inner pinion

bearing.

NOTE: The inner oil slinger must be placed between
gauge plate and inner pinion bearing when measuring the
pinion depth.

6. Install gauge plate J–39837–2, inner J–42827 stud

and nut J–21777–43 and outer pilot J–42824 to the
pinion bore.

7. Hold the stud stationary at the flats of the stud (and).

Tighten the stud nut
Torque: 2.2 N·m (1.6 lb ft)

8. Rotate the gauge plate and bearings several

complete revolutions to seat the bearings.

9. Tighten the stud nut until a torque of 1.6 to 2.2 N·m

(1.2 to 1.6 lb ft.) is required to keep the gauge plate in
rotation.

10. Assemble discs J–39837–1, arbor J–23597–1 and

dial indicator J–8001 to the side bearing bores.

NOTE: The bearing bores must be clean and burr-free.

420RW005

11. Install the side  bearing caps and tighten the bolts to

the specified torque.

Torque: 108 N·m (80 lb ft)

12. Rotate the gauge plate until the gauging area is

parallel with the discs.

13. Position the arbor assembly in the carrier so that the

plunger is centered on the gauge area of the gauge
plate.

14. Set the dial indicator to “0”. Place it on the mounting

post of the gauging arbor with the contact button
touching the indicator pad.
Force the dial indicator downward until the needle has
made a half turn clockwise. Tighten down the dial
indicator in this position.

15. Position the plunger on the gauge plate. Move the

gauging arbor slowly back and forth and locate the
position at which the dial indicator shows the greatest
defection. At this point, once again set the dial
indicator to “0”.
Repeat the procedure to verify the “0” setting.

425RS021

16. After the ZERO setting is obtained, rotate the gauging

arbor until the dial indicator rod does not touch the
gauging plate.
Record the number the dial indicator needle points to.

17. Record the pinion depth code on the head of the drive

pinion.
The number indicates a necessary change in the
pinion mounting distance. A plus number indicates
the need for a greater mounting distance (which can
be achieved by decreasing the shim thickness). A
minus number indicates the need for a smaller
mounting distance (which can be achieved by
increasing the shim thickness). If examination
reveals pinion depth code “0”, the pinion is “nominal”.

19. Remove bearing caps and depth gauging tools.
20. Install the correct pinion shim and inner oil slinger

onto pinion.

NOTE: Do not install pinion gear into housing at this time.

21. If the exciter ring was removed, install the new exciter

ring onto the differential case by pressing using the
ring gear as a pilot.

425RS047

22. Install ring gear(1) to the differential case(2)

425RW021

23. Install new ring gear bolts.

f

Tighten the ring gear bolts alternately in stages,
gradually pulling the ring gear onto the differential
case.

Tighten the ring gear bolts in sequence
Torque: 108 N·m (80 lb ft)

NOTE: Discard used bolts and install new ones.

415RS016

Side Bearing Preload Adjustment

1. The side bearing preload adjustment must be made

before installing the pinion.

2. The side bearing preload is adjusted by changing the

thickness of both hte left and right shims equally.  This
maintain the original backlash.

3. Install master side bearings J–39836 onto the case.

Remove all nicks, burrs, dirt etc., from the hubs to
allow the master bearings to rotate freely.
