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 CHECK

M1271000900377

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

M1271001100222

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
