PERIODIC MAINTENANCE
REAR WHEEL HUB
InspectionINFOID:0000000012431909
• Check the axle and suspension parts for excessive play, wear, or damage.
• Shake each rear wheel to check for excessive play as shown.
REAR WHEEL BEARING INSPECTION
• Move wheel in the axial direction by hand. Make sure the axial end play is within specification.
• Check that the wheel bearing operates smoothly.
• Replace the wheel bearing if the axial end play exceeds specification, or if the wheel bearing does not turn smoothly. Refer to RAX-6, "
Removal and Installation".
CAUTION:
The wheel bearing does not require maintenance. If any of the following symptoms are noted,
replace the wheel bearing.
• Growling noise is emitted from th e wheel bearing during operation.
• Wheel bearing drags or turns roughly.

Removal and InstallationINFOID:0000000012431911
REMOVAL
1. Remove the wheel and tire using power tool. Refer to WT-48, "Removal and Installation".
2. Separate rear wheel sensor from back plate. Refer to BRC-141, "
REAR WHEEL SENSOR : Exploded
View".
CAUTION:
When removing rear wheel hub, first separate rear wheel sensor from back plate. Failure to do so
may result in damage to rear wheel senso r wires, making rear wheel sensor inoperative.
3. Remove hub cap from brake drum using a suitable tool.
4. Remove wheel hub lock nut and brake drum. CAUTION:
• Do not depress brake pedal while rear drum is removed.
• Do not apply force to the brake drum to avoid dama ge to the wheel bearing. If the wheel bearing
inner race is separated due to force, replace the wheel bearing with a new one.
5. Remove spindle bolts. Separate back plate and spindle from rear suspension beam. CAUTION:
Do not remove rear brake comp onents. Support the rear brake components using wire.
6. If required, remove the wheel studs from brake drum using a suitable press.

• Do not hammer the wheel stud a nd avoid impact to the brake drum.
• Press the wheel stud straight out to avoid damage.
7. Perform inspection after removal. Refer to RAX-9, "
Inspection".
INSTALLATION
Installation is in the reverse order of removal.
• Position the stud (1) to the brake drum. Place a washer (A) on the
opposite end of the stud and by use of a nut (B), tighten to press
the stud into the brake drum.
CAUTION:
• Check that no clearance exists between brake drum, and the wheel stud after installation.
• Do not reuse wheel stud.
• Insert brake drum in a straight line onto the spindle. CAUTION:
• If the brake drum becomes stuck and must be pulled out, do not use tools. Replace the wheel bear-
ing with a new one if the brake drum canno t be pulled out without use of tools.
• If the brake drum becomes stuck and the wheel bearing inner race is damaged, replace the wheel
bearing with a new one.
• Do not damage the wheel bearing seal. If da maged, replace wheel bearing with new one.
• Using the Tool, install hub cap on brake drum as shown.
CAUTION:
• Do not reuse hub cap.
• Do not reuse wheel hub lock nut.
• Tighten the wheel hub lock nut to the specified torque. Refer
to RAX-6, "
Exploded View".
• Perform inspection after installation. Refer to RAX-9, "
Inspection".

3. Remove wheel bearing, using the Tool.
4. Perform inspection after disassembly. Refer to RAX-9, "
Inspection".
ASSEMBLY
1. Install wheel bearing (1) to brake drum (2), using the Tool (A).
CAUTION:
• Do not reuse wheel bearing.
• Do not apply lubri cating oil to the press-fit surface of the
wheel hub bearing.
• Install wheel bearing with the seal rubber part (B) faced to the brake drum side.
• Set brake drum and wheel bearing horizontally and insert
them vertically.
• The press-fit load must be applied to the wheel bearing outer race and the brake drum.
• Do not apply press-fit load to the wheel beari ng inner race, the seal (B) on the rubber surface
side, and the seal (C) on the metallic surface side. If a press-fit load is applied, the wheel bearing
must be replaced with a new one.
2. Install snap ring to brake drum. CAUTION:
• Do not damage the wheel bearing seal.
• The snap ring must be inst alled evenly into the groove.

INSPECTION AFTER REMOVAL
Check the brake drum and spindle for wear , cracks, and damage. Replace if necessary.
INSPECTION AFTER DISASSEMBLY
• Check brake drum for wear, cracks, or any other damage. Replace if necessary.
• Check snap ring for wear or cracks. Replace if necessary.
INSPECTION AFTER INSTALLATION
1. Check wheel bearing rotating torque per the following instructions. NOTE:
The adequacy of turning torque can be judged from a measurement value by a suitable tool.
a. Check the contact surface of the brake drum and spindle for foreign matter. If there is any foreign matter, clean the contact surface.
b. Check that the wheel hub lock nut is tightened to the specified torque.
c. Turn the brake drum 10 times or more bot h clockwise and counterclockwise for proper fit.
d. Set a suitable tool to the wheel nut and measure turning torque at turning speeds of 8 to 12 rpm.
2. Adjust parking brake operation (stroke). Refer to PB-4, "
Inspec-
tion and Adjustment".
