Make sure the mounting conditions (looseness, backlash) of each component and component status (wear,
damage) are normal.
WHEEL BEARING INSPECTION

Move wheel hub in the axial direction by hand. Make sure there
is no looseness of wheel bearing.

Rotate wheel hub and make sure there is no unusual noise or
other irregular conditions. If there are any irregular conditions,
replace wheel hub and bearing assembly.
Removal and InstallationEDS001XE
REMOVAL
1. Remove wheel and tire using power tool.
2. Remove engine under cover using power tool.
3. Without disassembling the hydraulic lines, remove caliper torque member bolts using power tool. Then
reposition brake caliper aside with wire. Refer to BR-21, "
REMOVAL" .
NOTE:

4. Put alignment mark on disc rotor and wheel hub and bearing
assembly, then remove disc rotor.
5. Remove cotter pin, then remove lock nut from drive shaft using power tool. Refer to FA X -7 , "
Removal and
Installation" .
6. Remove drive shaft from wheel hub and bearing assembly. Refer to FAX-7, "
Removal and Installation" .
7. Remove ABS sensor. Refer to BRC-64, "
Removal and Installation" .

Inspect the ABS sensor O-ring, replace the ABS sensor assembly if damaged.

Clean the ABS sensor hole and mounting surface with a suitable brake cleaner and clean lint-free shop
rag. Be careful that dirt and debris do not enter the axle bearing area.

Apply a coat of suitable grease to the ABS sensor O-ring and mounting hole.
CAUTION:
Do not pull on the ABS sensor harness.
8. Remove wheel hub and bearing assembly bolts using power tool.
9. Remove splash guard and wheel hub and bearing assembly from steering knuckle.
INSPECTION AFTER REMOVAL
Check for deformity, cracks and damage on each part, replace if necessary.
INSTALLATION
Installation is in the reverse order of removal.

Use new bolts when installing the wheel hub and bearing assembly.

When installing disc rotor on wheel hub and bearing assembly,
position the disc rotor according to alignment mark.
(When not using the alignment mark, refer to BR-21, "
Removal
and Installation of Brake Caliper Assembly and Disc Rotor" .)

When installing wheel and tire. Refer to WT-7, "Rotation" .

After driving the vehicle off-road through sand, mud, or water; more frequent maintenance may be required for
the following items:
Brake pads and rotors
Brake lines and hoses
Rear final drive oil, transmission fluid, and transfer fluid
Steering linkage
Drive shafts
Engine air cleaner filter
In-cabin microfilters
Schedule 1ELS001BL
