SYMPTOM PROCEDURES

INSPECTION PROCEDURE 1: Abnormal Noise

M12701000047USA0000010000

DIAGNOSIS

STEP 1. Check the rear hub assembly installation bolts for
looseness.

Q:Are the rear hub assembly installation bolts loosened?

YES:

 Tighten the rear hub assembly installation bolts to

the specified torque 95 ± 14 N·m (70 ± 10 ft-lb). Then
go to Step 3.

NO:

 Go to Step 2.

STEP 2. Check the wheel bearing end play.

(1)

Remove  the  caliper  assembly,  and  suspend  the  caliper
assembly with a wire and remove the brake disc.

ZC5018670000

(2)

Check the bearing's end play. Place a dial gauge against the
hub  surface,  then  move  the  hub  in  the  axial  direction  and
check whether or not there is end play.

Limit: 0.05 mm (0.002 inch)

Q:Is the wheel bearing end play within the limit?

YES:

 Go to Step 3.

NO:

 Replace the rear hub assembly, then go to Step 4.

STEP 3. Check the rear hub rotary-sliding resistance.

(1)

Remove  the  caliper  assembly,  and  suspend  the  caliper
assembly with a wire and remove the brake disc.

(2)

Turn the hub a few times to seat the bearing.

ZC5019790000

(3)

Wind a rope around the hub bolt and turn the hub by pulling
at  a  90  degree  angle  with  a  spring  balance.  Measure  to
determine whether or not the rotary-sliding resistance of the
rear hub is at the limit value.

Limit: 24.5 N (5.51 lb)

Q:Is the rear hub rotary-sliding resistance within the limit?

YES:

 Go to Step 4.

NO:

 Replace the rear hub assembly if an adjustment cannot

be made to within the limit. Then go to Step 4.

STEP 4. Retest the systems.

Q:Are abnormal noises generated?

YES:

 Return to Step 1.

NO:

 The procedure is complete.

REMOVAL AND INSTALLATION

M12701000020USA0000010001

｠

Do  not  disassemble  the  rear  wheel  hub
assembly.

｠

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 no
trouble prior to reassembling it.

ON-VEHICLE SERVICE

｠

When the rear wheel hub assembly is removed/
installed, make sure that the magnetic encoder
(integrated with inner oil seal) does not contact
with surrounding parts to avoid damage.

｠

When  removing  and  installing  the  rear  wheel
speed sensor, make sure that its pole piece at

the end does not contact with surrounding parts
to avoid damage.

｠

The part indicated with * is the bolt with friction
coefficient stabilizer. In removal, replace it with
a new one.
