NOTE
llAOl27
The grease in the repair kit should be divided in half for
use, respectively, at the joint and inside the boot.
(3) Secure the boot bands.
Caution
The boot bands should be tightened with the drive

(2) Remove the drive shaft and inner shaft assembly (L.H.)
from the transaxle by lightly tapping the T.J. case with a
plastic hammer, etc.
(3) Remove the drive shaft (R.H.) as described below.
Insert a pry bar between the transaxle case and the
drive shaft, and then pry the drive shaft from the
transaxle.
Caution
1. Do not pull out the drive shaft; doing so will damage the T.J.; be sure to use the pry bar.
2.Do not insert the pry bar so deep as to damage
the oil seal.
Inset-t a pry bar at the projection part and remove the
drive shaft
(R.H.) from the transaxle.
Caution
Do not pull out the drive shaft; doing so will
damage the T.J.; be sure to use the pry bar.
INSPECTION l Check the drive shaft boot for damage or deterioration.
l Check the ball joints for wear or operating condition.
l Check the spline part for wear or damage.

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.

(4) Secure the B.J. boot with boot bands (A) and (C) to the
drive shaft and B.J.
Caution
Ensure that the B.J. is at a zero angle with the drive
shaft to ensure the boot contains the specified
amount of air.
7. INSTALLATION OF D.O.J. INNER RACE, CAGE AND
BALL ASSEMBLY
(1) Apply the specified grease to the D.O.J. cage, the balls and the D.O.J. inner race.
Specified grease: Repair kit grease (As required)
(2) Install the cage, balls and inner race to the drive shaft, then, using snap ring pliers, fit the snap ring securelyinto the groove in the shaft.
5. APPLICATION OF GREASE TO D.O.J. OUTER RACE (1) Fill the specified grease to the D.O.J. outer race, fit thedrive shaft into the D.O.J. outer race, and then fill more
grease to the D.O.J. outer race.
Specified grease: Repair kit grease90 g (3.2 OZ.)
Caution
The grease in the repair kit should be divided in half
for use, respectively, at the joint and inside the
boot.
A special type of grease is used on the joint. Be
cautious to ensure that no other grease is allowed
to come in contact with the joint.
(2) Install the circlip
to the D.O.J. outer race.
(3) Assemble the D.O.J. boot to the D.O.J. outer race, then secure the boot to the drive shaft with boot band
(C).
(4) Place boot band (B) on the D.O.J. boot.
NOTE
Do not secure boot band (B).
(5) Set the D.O.J. boot bands at the specified distance in order to adjust the amount of air inside the D.O.J. boot,
and then tighten the D.O.J. boot band (C) securely.
Standard value:
76f3 mm @JO+ 23 in.)
(6) Release a part of the D.O.J. boot from the D.O.J. outer race to allow pressure to escape from the boot.
(7) Tighten boot band
(B) and secure the D.O.J. boot.

NOTE
(1)Tooth contact pattern is a method for judging the result of the adjustme\
nt of drive pinion height and final drive gear
backlash. The adjustment of drive pinion hight and final drive gear back\
lash should be repeated until tooth contact
patterns bear a similarity to the standard tooth contact pattern.
(2) When adjustment is not able to obtain a correct pattern, it may be judg\
ed that the drive gear and drive pinion have exceed their usage limits and both gears should be replaced as a set.
