MB991 056 orMB991 001! 12A05542. REMOVAL OF OIL SEAL (DRIVE SHAFT SIDE)
Remove the oil seal (drive shaft side) from the knuckle.
5. REMOVAL OF WHEEL BEARING
(1) Crush the oil seal in two places so that the tabs of the
special tool will be caught on the wheel bearing inner
race.(2) Remove the wheel bearing inner race from the front
hub by using the suitable puller.
NOTEBe careful that the front hub will not fall down at the
wheel bearing inner race (outer side) removed from the
hub.(3) Remove the snap ring from the knuckle.
(4) Remove the bearing by using the special tools.
Caution
Removal is easier if the outer side inner race
removed from the hub is placed on the bearing and
the wheel bearing is then removed.
INSPECTIONNOZffiAkh
0Check the front hub and brake disc mounting surfaces for
galling and contamination.
l Check the knuckle inner surface for galling and cracks.
0 Check for defective bearing.

NOZIHAN5. INSTALLATION OF WHEEL BEARING
A(1) Fill the wheel bearing with multipurpose grease.
-(2) Apply a thin coating of multipurpose grease to the
knuckle and bearing contact surfaces.
Grease: MOPAR Multi-mileage Lubricant
Part No.2525035 or equivalent
(3) With the wheel bearing inner race removed, press-in
the bearing by using the special tools.
(4) Install the wheel bearing inner race to the wheel
bearing.4. INSTALLATION OF OIL SEAL (HUB SIDE)
(1) Drive the oil seal (hub side) into the knuckle by using
the
soecial tools until it is flush with the knuckle end
surface.A(2) Apply multipurpose grease to the lip of the oil seal and
to the surfaces of the oil seal which contact the front
hub.Grease: MOPAR Multi-mileage Lubricant
Part No.2525035 or equivalent
1. INSTALLATION OF FRONT HUB
(1) Use the special tool to mount the front hub assembly
onto the knuckle.
(2) Tighten the nut of the special tool to 200-260 Nm
(144-188
ft.lbs.).(3) Rotate the front hub assembly in order to seat the
bearing.l ADJUSTMENT OF WHEEL BEARING STARTING
TORQUE(1) Measure the wheel bearing starting torque (hub
starting torque) by using the special tools.
Limit: 1.8 Nm (16
in.lbs.) or lessic
‘-NOTEThe starting torque must be within the limit and, in
addition, the bearing must not feel rough when
rotated.

8. REMOVAL OF DRIVE SHAFT.’
(1) Use the suitable tool to push out the drive shaft from
the front hub.
(2)

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 on 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 the damage
the oil seal.
A/T>Refer to
P.2-23.Caution
Do not apply the vehicle weight to the wheel bearing
while the drive shaft is disconnected. If the vehicle
weight must unavoidably be applied (because of
vehicle movement or some other reason), use the
special tool to hold the wheel bearing, as shown in the
figure.
INSPECTIONN62CXACl 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 POINTS OF INSTALLATION
N62aoAJ5. INSTALLATION OF LOWER ARM BALL JOINT
Lower the vehicle to the ground and tighten the knuckle to
the lower arm ball joint connecting nut.
3.INSTALLATlON OF WASHER/2. DRIVE SHAFT NUT/l.
COTTER PIN(1) Be sure to install the washer and wheel bearing nut in
the specified direction.
(2) After installing the wheel, lower the vehicle to the
ground and finally tighten the wheel bearing nut.
(3) If the position of the cotter pin holes does not match,
tighten the nut up to 260 Nm (188
ft.lbs.) in maximum.
(4) Install the cotter pin in the first matching holes and
bend it securely.
