4. Set the dial indicator 5–8840–0126–0 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.

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”.

found through inspection.
Check the following parts:
Ring gear, pinion gear
Bearing
Side gear, pinion mate gear, differential shaft
Differential cage, carrier
Thrust washer

Ring gear replacement:
1. The ring gear should always be replaced with the
drive pinion as a set.
2. Clean the ring gear threaded holes to remove the
locking argent.
3. Discard used bolts and install new ones.
4. When installing the ring gear, apply LOCTITE 271 or
