GENERAL INFORMATION

M1271000100304

The rear axle has the following features:

• The wheel bearing is a unit ball bearing (dou-

ble-row angular contact ball bearing) which incor-
porates the oil seals and is highly resistant to a
thrust load.

• ABS rotor for detecting the wheel speeds is

press-fitted to the rear hub.

ON-VEHICLE SERVICE

WHEEL BEARING AXIAL PLAY CHECK

M1271000900452

1. Remove the caliper assembly, and suspend the

caliper assembly with a wire and remove the
brake disc.

AC303736 AB

2. Check the bearing's axial play. Place a dial gauge

against the hub surface; then move the hub in the
axial direction and check whether or not there is
axial play.

Limit: 0.05 mm

3. If the play exceeds the limit, the self-locking nut

should be tightened to the specified torque and
check the axial play again.

Tightening torque: 175

± 25 N⋅ m

4. Replace the rear hub assembly if an adjustment

cannot be made to within the limit.

REAR HUB ROTARY-SLIDING
RESISTANCE CHECK

M1271001100244

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.

AC303737

3. Wind a rope around the hub bolt and turn the hub

by pulling at a 90

° 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: 19 N

4. If limit value is exceeded, loosen the self-locking

nut and then tighten it to the specified torque and
check the rear hub rotary sliding resistance again.

Tightening torque: 175

± 25 N⋅ m

5. Replace the rear hub assembly if an adjustment

cannot be made to within the limit.

HUB BOLT REPLACEMENT

M1271001000258

tighten the caliper assembly mounting bolts to the
specified torque 60

± 5 N⋅ m.

CAUTION

• Care must be taken not to scratch or damage the teeth of the ABS rotor. The ABS rotor must never

be dropped. If the teeth of the ABS rotor are chipped, resulting in a deformation of the ABS rotor,
it will not be able to accurately detect the wheel rotation speed, and the system will not function
normally.

The rear hub assembly should not be dismantled. When removing the rear hub assembly, the
wheel bearing inner race may be left at the spindle side. In this case, always replace the rear hub
assembly, otherwise the hub will damage the oil seal, causing oil leaks or excessive play.
