13. Remove steering knuckle from vehicle.
INSPECTION AFTER REMOVAL
Check for deformity, cracks and damage on each parts, replace if necessary.
Ball Joint Inspection
Check for boot breakage, axial looseness, and torque of transverse link and steering outer socket ball joint.
Refer to FSU-14, "
TRANSVERSE LINK" , PS-18, "POWER STEERING GEAR AND LINKAGE" .
INSTALLATION
CAUTION:
Be sure to replace the new differential side oil seal every removal of drive shaft. Refer to FFD-11,
"SIDE OIL SEAL" .

Refer to FAX-10, "Removal and Installation" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

To assemble disc rotor and wheel hub and bearing assembly,

PRECAUTIONS
Revision: 2006 July 2007 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.
