Use removed drive pinion lock nut and washer only for the pre-
load measurement.
d. Rotate drive pinion at least 20 times to check for smooth opera-
tion of the bearing.
e. Tighten to drive pinion lock nut, while adjust pinion bearing pre-
load torque.
CAUTION:
lAdjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
lDrive pinion lock nut is tightened with no collapsible spacer. Be careful not to overtighten it.
While measuring the preload, tighten it by 5°to 10°.

Service Notice or PrecautionEDS003AI
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 a new ones if necessary.
lGaskets, seals and O-rings should be replaced any time when 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 for each vehicle, if necessary.
Wiring Diagrams and Trouble DiagnosisEDS003AJ
