Differential Assembly: Service Precautions

Service Notice or Precautions
^ Check 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.
^ Overhaul should be done in a clean work area, it is preferable to work in dustproof area.
^ Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of the unit, preventing them from entering into the unit during disassembly or assembly.
^ Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them with a new ones if necessary.
^ Gaskets, seals and O-rings should be replaced any time when the unit is disassembled.
^ In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tightening sequence is specified, observe it.
^ Clean and flush the parts sufficiently and blow-dry them.
^ Be careful not to damage sliding surfaces and mating surfaces.
^ When applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil, and foreign materials from the application and mounting surfaces. Always use shop paper for cleaning the inside of components.
^ Avoid using cotton gloves or shop rags to prevent entering of lint.
^ During assembly, observe the specified tightening torque, and apply new gear oil, petroleum jelly, or multi-purpose grease as specified for each vehicle, if necessary.
