Check boot for cracks or other damage, and also for grease
leakage.

If a trouble is found, disassemble drive shaft, and then replace
with new one.
INSTALLATION

Refer to FAX-13, "Removal and Installation (Right Side)" for tightening torque. Install in the reverse order
of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

Check the following item after service.
–Installation condition of wheel sensor harness.

Place the protector [SST: KV38107900 ( – )] onto transaxle
to prevent damage to the oil seal while inserting drive shaft.
Slide drive shaft sliding joint and tap with a hammer to install
securely. (right side)
CAUTION:
Be sure to check that circular clip is securely fastened.

PRECAUTIONS
Revision: 2006 December 2006 FX35/FX45
PRECAUTIONSPFP:00001
Service Notice or PrecautionsNDS000B3

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.
