lInspection is required when detecting any noise or malfunction while driving or turning. Improper condition
of oil or differential case assembly is suspected. Refer toRFD-3, "
METHOD FOR TROUBLESHOOTING"
.
METHOD FOR TROUBLESHOOTING
1. Check differential gear oil level and differential gear oil leakage. Refer toRFD-9, "Checking Differential
Gear Oil".
2. Changing differential gear oil. Refer toRFD-9, "
Changing Differential Gear Oil".
3. Start engine. Drive for 10 min.
4. Again changing differential gear oil. Refer toRFD-9, "
Changing Differential Gear Oil".
5. Start engine. Drive for 10 min. Check if any noise or improper oil condition is detected.
lIf OK, check differential gear oil level and differential gear oil leakage. Refer toRFD-9, "Checking Differ-
ential Gear Oil".
lIf NG, replace differential case assembly after checking each part of final drive. Refer toRFD-15, "Dis-
assembly and Assembly".
Service Notice or PrecautionsEDS0038Z
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 new ones if necessary.
lGaskets, seals and O-rings should be replaced any time 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.
