lBefore starting diagnosis of the vehicle, understand the symptoms well. Perform correct and systematic
operations.
lCheck for the correct installation status prior to removal or disassembly. When matching marks are
required, be certain they do not interfere with the function of the parts they are applied to.
lOverhaul should be done in a clean work area, a dust proof area is recommended.
lBefore disassembly, completely remove sand and mud from the exterior of the unit, preventing them from
entering into the unit during disassembly or assembly.
lAlways use shop paper for cleaning the inside of components.
lAvoid using cotton gloves or a shop cloth to prevent the entering of lint.
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.
lClean and flush the parts sufficiently and blow them dry.
lBe careful not to damage sliding surfaces and mating surfaces.
lWhen applying sealant, remove the old sealant from the mating surface; then remove any moisture, oil,
and foreign materials from the application and mating surfaces.
lIn principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If a
tightening sequence is specified, observe it.
lDuring assembly, observe the specified tightening torque.
lAdd new differential gear oil, petroleum jelly, or multi-purpose grease, as specified.
