Inspection and Repair
Make all necessary adjustments, repairs, and part replacements if wear, damage, or other problems are discovered
during inspection.
• Ring gear, pinion gear
• Bearing
• Side gear, pinion gear, cross pin
• Differential cage, carrier
• Thrust washer
• Oil seal
Visual Check
Inspect the following parts for wear, damage, or other
abnormal conditions.
Ring Gear Replacement
(1) The ring gear should always be replaced with the drive pinion as a set.
(2) W hen installing the ring gear, apply LOCTITE 271 o
r
equivalent to the threaded hole and bolt.
(3) Tighten the fixing bolts in a diagonal sequence as illustrated.
(4) Discard used bolts and install new ones.

4. Adjust Shim
Adjustment of drive pinion mounting distance
(1) Apply gear oil to the inner and outer drive pinion bearing.
Clean the pinion setting gage set.
Then install the gage set together with the inner and oute
r
bearings.

New bearing 2.3 (0.23/20)
Used bearing 0.98 - 1.18
(0.10 – 0.12/9 – 10)
(2) 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 N ⋅m (kgf ⋅m/lb ⋅ft)
98 (10.0/72)
1 Dial indicator : 5-8840-0126-0
2 Disc (2 pcs.) : 5-8840-2088-0
3 Arbor : 5-8840-0128-0
4 Gage plate : 5-8840-2087-0
(3) Set the dial indicator to “0”. Place it on the mounting post of
the gaging 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.
(4) Position the plunger on the gage plate. Move the gaging
arbor slowly back and forth and locate the position at which
the dial indicator shows the greatest deflection. At this
point, once again set the dial indicator to “0”.
Repeat the procedure to verify the “0” setting.

(5)
After the ZERO setting is obtained, rotate the gaging arbor
until the dial indicator rod does not touch the gaging plate.
Record the number the dial indicator needle points to.
(6) 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 b
y
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”.
