Revision: 2004 November 2004 FX35/FX45
FRONT WHEEL HUB AND KNUCKLEPFP:40202
On-Vehicle Inspection and ServiceADS000OL
Make sure the mounting conditions (looseness, back lash) 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 InstallationADS000OM
REMOVAL
1. Remove tire from vehicle with power tool.
2. Remove brake caliper with power tool. Hang it in a place where it will not interfere with work. Refer to BR-
20, "FRONT DISC BRAKE" .
NOTE:
Avoid depressing brake pedal while brake caliper is removed.
3. Remove disc rotor.
4. Remove wheel sensor from wheel hub and bearing assembly. Refer to BRC-57, "
WHEEL SENSORS" .
CAUTION:
Do not pull on wheel sensor harness.
5. Remove cotter pin at steering outer socket, then loosen mounting nut.Axial end play : 0.05 mm (0.002 in) or less

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.

After removing/installing or replacing axle components, check wheel alignment. Refer to FSU-6, "Wheel
Alignment Inspection" .

After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" .

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

tank.
11. Remove fuel tank.
INSTALLATION
Note the following, and install in the reverse order of removal.

Surely clamp fuel hoses and insert hose to the length below.

Be sure hose clamp is not placed on swelled area of fuel tube.

Tighten clamps of fuel filler hose so that the remaining length of screw thread becomes 8 to12 mm (0.31
to 0.47 in) on tank side and 5.7 to 9.7 mm (0.224 to 0.382 in) on fuel filler tube side.

To connect quick connector, refer to FL-7, "Quick Connector" .
INSPECTION AFTER INSTALLATION
Use the following procedure to check for fuel leaks.
1. Turn ignition switch “ON” (with engine stopped), and check connections for leakage by applying fuel pres-
sure to fuel piping.
2. Start engine and check for fuel leaks at the fuel system tube and hose connections.

After removing/installing rear suspension assembly, make sure to adjust wheel alignment and then, adjust
neutral position of steering angle sensor. Refer to RSU-5, "
Wheel Alignment Inspection" and BRC-6,
"Adjustment of Steering Angle Sensor Neutral Position" .
