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:2.3N·m  (20 lb in)

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.

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.

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".
