REAR AXLE27-2
GENERAL INFORMATION
M1271000100304
The rear axle has the following features:
•The wheel bearing is a unit ball bearing
(double-row angular contact ball bearing) which
incorporates 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 in vehicles with ABS.

WHEEL BEARING AXIAL PLAY CHECKM1271000900452
1. Remove the caliper assembly, and suspend the
caliper assembly with a wire and remove the
brake disc.
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.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 REPLACEMENTM1271001000258
1. Remove the caliper assembly and suspend it with
wire so that it does not fall.
2. Remove the brake disc.
3. Use special tool hub bolt remover (MB991618) to
remove the hub bolts.
4. Install the plain washer to the new hub bolt, and
install the bolt with a nut while holding the hub
with special tool end yoke holder (MB990767).
5. Install the brake disc, caliper assembly and
tighten the caliper assembly mounting bolts to the
specified torque 60 ± 5 N⋅m.

REMOVAL AND INSTALLATIONM1271002000381
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.

WHEEL BALANCE ACCURACYM1311001700247
PURPOSE
This section contains tips and procedures for
achieving accurate wheel balance. Steering wheel
vibration and/or body shake can result if any of these
procedures are not carefully observed.
1. Wheels and tyres must be properly mounted on a
balancer in order to achieve correct balance.
Centring the wheel on the shaft of the balancer is
essential for proper mounting.
2. Off-the-car wheel balancers must be calibrated
periodically to ensure good balancing results. An
inaccurately calibrated balancer could cause
unnecessary replacement of tyres, shocks,
suspension components, or steering components.
Check your balancer's calibration approximately
every 100 balances. Your wheel balancer's
instruction manual should include calibration
procedures. If the calibration procedures specifically
for your balancer are missing, use the generic steps
in this section for zero calibration, static balance, and
dynamic balance checks. The wheel balancer
calibration checks are also described in the
flowchart. (Refer to P.31-6).
PROCEDURE
1. Confirm that the balancer's cone and the wheel
mounting cone are undamaged and free of dirt
and rust.
2. On this vehicle, the wheel's centre hole on the
hub side has a chamfered edge. Use a
back-mounting cone on your wheel balancer to
centre the wheel on the balancer shaft.
3. Install a wheel mounting cone. The appropriate
size cone for this vehicle is 67.0 mm.
4. Before balancing the wheel, remove any wheel
weights from both sides. Also check both sides for
any damage.
5. When installing wheel weights, hammer them at a
straight (not diagonal) angle. Scalloped

or out-of-alignment suspensionRotate the tyres, and
