FRONT AXLE HUB ASSEMBLY

REMOVAL AND INSTALLATION

M1261001701356

CAUTION

• The magnetic encoder collects metallic particles easily, because it is magnetized. Make sure that

the magnetic encoder should not collect metallic particles. Check that there is not any trouble
prior to reassembling it.

• When removing and installing the front wheel hub assembly, make sure that the magnetic encoder

(integrated with the inner oil seal) does not contact with surrounding parts to avoid damage.

• When removing and installing the front wheel speed sensor, make sure that the sensor head at the

end does not contact with surrounding parts to avoid damage.

• During maintenance, take care not to contact the parts or tools to the caliper because the paint of

caliper will be scratched. And if there is brake fluid on the caliper, wipe off quickly.

•

Post-installation operation
• Using your fingers, press the Ball Joint Dust Cover to

check for a crack or damage.
