4. Set the dial indicator J–8001 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.

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 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”.

4. Place the shim (1) on the drive pinion, then install the

inner bearing (2) onto the pinion by using installer
J–42828 and a press .

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

425RW024

5. Install collapsible spacer. Discard the used

collapsible spacer and install a new one.

6. Install drive pinion shaft assembly.
7. Install outer bearing.
8. Use oil seal installer J–37263 to install a new oil seal

that has grease on seal lip.

425RS025

9. Install flange assembly.

10. Install flange nut and washer.

1. Apply lubricant to the pinion threads.

2. Using the pinion flange holder J–8614–01, tighten

the nut only enough to remove the shaft end play.

NOTE: Discard used flange nut and install new one.

415RW006

3. Adjust pinion bearing preload.

a. Measure the bearing preload by using a torque

meter and note the scale reading required to
rotate the flange.

b. Continue tightening flange nut until the specified

starting torque is obtained.

Starting torque: 1.1–1.6 N·m (10–14 lb in)

NOTE:

a. Do not overtighten or loosen and then retighten the

nut.

b. Pinion nut torque should be in the range of

298–380 N·m (220–281 Ib ft).

4. Using punch J–39209, stake the flange nut at two

points.

NOTE: When staking, be sure to turn the nut to ensure
that there is no change in bearing preload. Make sure of
preload again as instructed in 3).

425RS028

11. Adjust ring gear backlash.

1. Attach the side bearing to the differential

assembly without shims by using installer
J–42829 and grip J–8092.
