PRECAUTIONS
PRECAUTIONS
PFP:00001
CautionEDS00101
●Before starting diagnosis of the vehicle, understand symptoms well. Perform correct and systematic oper-
ations.
●Check for the correct installation status prior to removal or disassembly. When mating 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 of
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 malfunc-
tion is detected, replace it with a new one.
●Normally replace lock pins, oil seals, and bearings with new ones every time 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 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 a shop cloth to prevent entering of lint.
●During assembly, observe the specified tightening torque, and apply new differential oil, Vaseline, or Nis-
san MP Special Grease No. 2, as specified for each vehicle, when necessary.
●Do not reuse drained oil. Discard waste oil after oil changes or part treatment in accordance with local
laws and regulations.
Precautions for Brake SystemEDS00102
●When installing rubber parts, final tightening must be carried out under unladen condition* with tires on
ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions.
●After installing removed suspension parts, check wheel alignment and adjust if necessary.
●Use flare nut wrench when removing or installing brake tubes.
●Always torque brake lines when installing.
