REAR AXLE <FWD>
WHEEL BEARING END PLAY INSPECTION
1. Inspect the play of the bearings while the vehicle is jacked
up and resting on floor jack.
2. Remove the hub cap and then release the parking brake.
3. Remove the caliper assembly and the brake disc.
4.
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 (.002 in.) or less
NOTE
If the limit value is exceeded, the lock nut should be
tightened to the specified torque and check the end play
again.
5. Replace the rear hub bearing unit if an adjustment cannot
be made to within the limit.
REAR HUB ROTARY-SLIDING RESISTANCE (TOR-
QUE) INSPECTION
1. Inspect the play of the bearings while the vehicle is jacked
up and resting on floor jack.
2. Release the parking brake.
3. Remove the caliper assembly and the brake disc.
4.
After turning the huba few times to seat the bearing, attach
a spring balance to the hub bolt, and, pulling at a 90" angle
from the hub bolt, measure to determine whether or not
the rotary-sliding resistance of the rear hub (the rotary-
sliding torque of the rear hub) is the standard value.
Limit:
Rear hub rotary-sliding resistance
Rear hub rotary-sliding torque
NOTE
If the limit value is exceeded, loosen the nut and then
tighten it to the specified torque, and check the rear hub
rotary-sliding torque again.
