DIFFERENTIAL (FRONT)

Reassembly

1. Using installer J–7817 and grip J–8092, install outer

bearing outer race.

415RW013

2. Using installer J–7818 and grip J–8092, install Inner

bearing outer race.

415RW014

3. Install adjust shim and adjust drive pinion mounting

distance:
1. Apply gear oil to the inner and outer drive pinion

bearing.
Clean the pinion setting gauge set.
Then install the gauge set together with the inner
and outer bearings.

2. Tighten the nut to the specified torque.

Torque: 2.3 N·m (20 lb in)

Legend

(1) Pilot : J–21777–42
(2) Pilot : J–42479–2
(3) Gauge Plate : J–42479–1
(4) Nut and Stud : J–21777–43

3. Clean the side bearing bores. Install the dial

indicator with the discs and arbor. Install and
tighten the bearing caps to the specified torque.

Torque: 97 N·m (72 lb ft)

Legend

(1) Dial Indicator: J–8001
(2) Gauge Plate: J–42479–1
(3) Disc (2 pcs.): J–23597–8
(4) Arbor: J–23597–1

4. 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.

5. 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

6. 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.

425RS022

Legend

(1) Example=Dial indicator reading of 0.085

7. 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 indi-
cates 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 ex-
amination reveals pinion depth code “0”, the pin-
ion is “nominal”.

4. Place the shim on the drive pinion. Install the inner

bearing onto the pinion using an installer J–6133–01
and a press.

NOTE: Do not apply pressure to the roller cage and apply
pressure only to the inner race.

425RW036

5. Discard the used collapsible spacer and install a new

one.

6. Install pinion gear.
7. Install outer bearing.
8. Install oil seal slinger.
9. Use oil seal installer J–24250 to install a new oil seal

that has been soaked in front axle lubricant.

NOTE: Take care to use a front differential oil seal, NOT
the rear differential oil seal.

415RS011

10. Install flange.

11. Install flange nut.

1. Apply lubricant to the pinion threads.

2. Tighten the nut to the specified torque using the

pinion flange holder J–8614–01.

Torque: 217N·m (160 lb ft)

NOTE: Discard used flange nut and install new one and
do not over tighten the flange nut.

415RW006

3. Adjust pinion bearing preload.

a. Measure the bearing preload by using a torque

meter. Note the scale reading required to
rotate the flange.

b. Continue tightening flange nut until the

specified starting torque is obtained.

Starting torque: 1.2–1.9 N·m(10–17 lb in)

NOTE: Do not tighten the flange nut more than
678 N·m(500 lb ft).
