Differential Assembly: Service Precautions

Precautions

CAUTION:
^ Before starting diagnosis of the vehicle, understand symptoms well. Perform correct and systematic operations.
^ Check for the correct installation status prior removal or disassembly. When matching marks are required, be sure they do not interfere with the function of the parts they are applied to.
^ Carry out an overhaul in a clean work place, Using a dust proof room is recommended.
^ Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior to the unit, preventing them from entering into the unit during disassembly or assembly.
^ Check appearance of the disassembled parts for damage, deformation, and abnormal wear. If a malfunction is detected, replace it with a new one.
^ Normally replace lock pins, oil seals, and bearings with new ones every times they are removed.
^ 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 them dry.
^ Be careful not to damage the sliding surfaces and mating surface.
^ 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 a shop cloth to prevent entering of lint.
^ During assembly, observe the specified tightening torque, and new differential gear oil, Vaseline, or multi-purpose grease, as specified for each vehicle, when necessary.
