Service Notice or PrecautionEDS003AI
lCheck for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts when applied.
lOverhaul should be done in a clean work area, it is preferable to work in dust proof area.
lBefore disassembly completely remove sand and mud from the exterior of the unit, preventing them from
entering into the unit during disassembly or assembly.
lCheck appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.
lGaskets, seals and O-rings should be replaced any time when the unit is disassembled.
lIn principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
lClean and flush the parts sufficiently and blow-dry them.
lBe careful not to damage sliding surfaces and mating surfaces.
lWhen applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
lAlways use shop paper for cleaning the inside of components.
lAvoid using cotton gloves or shop rags to prevent entering of lint.
lDuring assembly, observe the specified tightening torque, and apply new differential gear oil, petroleum
jelly, or multi-purpose grease as specified for each vehicle, if necessary.

1. Remove the rear propeller shaft. Refer toPR-8, "Removal and Installation".
2. Remove the rear tires.
3. Remove rear drum brake. Refer toBR-31, "
Removal and Installation of Drum Brake Assembly".
4. Rotate the drive pinion back and forth 2 to 3 times using Tool
and record the rotating torque.
5. Remove the drive pinion lock nut and washer using Tool.
6. Put a matching mark on the thread edge of drive pinion. The
mark should be in line with the mark on companion flange.
CAUTION:
For matching mark, use paint. Do not damage drive pinion
and companion flange.

4. Rotate the drive pinion using Tool. Rotating torque should be
equal to the reading recorded in step 4 above during removal
plus an additional 0.56 N·m (5 in-lb).
5. If the rotating torque is low, continue to tighten the drive pinion
lock nut in 6.8 N·m (5 ft-lb) increments without overtightening.
Refer toRFD-82, "
COMPONENTS". Tighten until proper rotat-
ingtorqueisachieved.
CAUTION:
lDo not loosen the drive pinion lock nut to decrease drive
pinion rear bearing rotating torque.
lDo not exceed specified rotating preload torque. If preload torque or rotating torque is exceeded
a new collapsible spacer must be installed.
lDo not exceed maximum tightening torque. If maximum tightening torque is reached prior to
reaching the required rotating torque, the collapsible spacer may have been damaged. Replace
the collapsible spacer.
