SERVICE ADJUSTMENT PROCEDURES
WHEEL BEARING END PLAY ADJUSTMENTmw

1.Inspect the play of the bearings while the vehicle is jacked
up and resting on floor jack.
2.If there is any play, remove the hub cap, cotter pin, and lock
cap, and then loosen the lock nut.
3.After tightening the lock nut to 20 Nm (14 ft.lbs.1, turn the
hub a few times to seat it to the bearing.
4. In order to seat the bearing properly, turn the hub (brake drum) 180” or more and then return it 360” or more; repeat
this procedure again three or more times.
5. Return the lock nut to 0 Nm
(0 ft.lbs.).
6.After tightening the lock nut at a torque of 10 Nm (7 ft.lbs.1,
rotate the hub again in the same way as described in step 4
so as to seat the bearing.
7. Then once again tighten the lock nut to 10 Nm (7
ft.lbs.).
8. Install the lock cap and cotter pin. If the position of the cotter pin is not matched with the
holes of the lock cap, reposition the lock cap so that the
holes align. If this can not be accomplished, back off the nut
by not more than 15”.
Caution
Check to be sure that the lock nut cannot be loosened
manually.
9.After setting the cotter pin in place, seat the bearing in the
same manner as in step 4.

10. After securing the wheel nuts, attach a spring balance and
rope 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 is the standard value.
Standard value: Rear hub rotary-sliding resistance
When a new bearing is used 14
N (3.08 Ibs.) or less
When the bearing is reused 11
N (2.42 Ibs.) or less
NOTE
If the standard value is exceeded, the lock nut should be
tightened or the bearing replaced.
11. 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 mm (0 in.)
12. If there is any play, the lock nut should be tightened or the
bearing replaced.
13. After checking, be sure the hub rotates smoothly and that
the cotter pin is correctly installed.

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 (.0020 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.
