I
Before removing the rear wheel hub assembly, disconnect
the ABS wheel sensor from the assembly. Then move it
away from the hub assembly. Failure to do so may result
in damage to the sensor wires and the sensor becoming
inoperative.
I
Wheel hub bearing does not require maintenance. If any of
the following symptoms are noted, replace wheel hub
bearing assembly.
1)
Growling noise is emitted from wheel hub bearing dur-
ing operation.
2)
Wheel hub bearing drags or turns roughly. This occurs
when turning hub by hand after bearing lock nut is tight-
ened to specified torque.
