1. Remove the caliper assembly and suspend it with
a wire.
2. Remove the brake disc from the front hub.
3. Attach a dial gauge as shown in the illustration,
and then measure the axial play while moving the
hub in the axial direction.
Limit: 0.05 mm
4. If axial play exceeds the limit, disassemble the
front hub assembly and check the parts.
5. Install the brake disc, caliper assembly and
tighten the caliper assembly mounting bolts to the
specified torque 100 ± 10 N⋅m.

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.

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.
