Removal and InstallationEDS003I9
REMOVAL
1. Remove wheel.
2. Remove ABS sensor harness from mount on knuckle, then disconnect ABS sensor harness connector.
CAUTION:
Do not pull on ABS sensor harness.
3. Remove steering knuckle. Refer toFSU-16, "
Removal and Installation".
4. Using a slide hammer, remove the drive shaft from final drive.
CAUTION:
lWhen removing drive shaft from vehicle, be careful to
avoid interfering with brake hose, ABS wheel speed sen-
sor harness, and other parts.
lWhen removing drive shaft, do not apply an excessive
angle (22°or more) to drive shaft joint. Also be careful
not to excessively extend slide joint.
INSPECTION AFTER REMOVAL
lMove joint up, down, left, right, and in axial direction. Check for any rough movement or significant loose-
ness.
lCheck boot for cracks or other damage, and for grease leakage.
lIf damaged, disassemble drive shaft to verify damage, and
repair or replace as necessary.

INSTALLATION
Installation is in the reverse order of removal.
lWhen installing drive shaft onto front final drive, use Tool to pre-
vent damage to the oil seal while inserting drive shaft. Slide
drive shaft sliding joint and tap with a hammer to install securely.
CAUTION:
Be sure to check that circlip is securely fastened.
Never reuse the differential side oil seal.
Disassembly and AssemblyEDS003IA
DISASSEMBLY
Final Drive Side
1. Mount the drive shaft in a vise.
CAUTION:
When mounting the drive shaft in a vise, use copper or aluminum plates between the vise and the
drive shaft.
2. Remove boot bands and slide the boot back.
3. Put matching marks on housing and shaft before separating joint assembly.
CAUTION:
Use paint or similar substance for matching marks. Do not scratch the surfaces.Tool number : KV38105500

PRECAUTIONS
PRECAUTIONS
PFP:00001
ServiceNoticeorPrecautionsEDS0034W
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.

DRAINING
1. Stop the engine.
2. Remove the drain plug and gasket. Drain the gear oil.
3. Install the drain plug with a new gasket to the final drive assem-
bly. Tighten to the specified torque. Refer toFFD-17, "
