REMOVAL
NMAX0009
CAUTION:
Wheel hub bearing usually does not require maintenance. If
any of the following symptoms are noted, replace wheel hub
bearing assembly.
I
Growling noise is emitted from wheel hub bearing during
operation.
I
Wheel hub bearing drags or turns roughly. This occurs when
turning hub by hand after bearing lock nut is tightened to speci-
fied torque.
I
If the wheel hub bearing assembly is removed, it must be
renewed. The old assembly must not be re-used.
Remove brake caliper assembly and rotor.
Before removing the front axle assembly, disconnect the ABS
wheel sensor from the assembly. Then move it away from the
front axle assembly area.
Failure to do so may result in sensor wires being damaged
and the sensor becoming inoperative.
Suspend caliper assembly with wire so as not to stretch brake
hose.
Be careful not to depress brake pedal, or piston will pop out.
