SERVICE POINTS OF DISASSEMBLYM26lFAP2. REMOVAL OF HUB AND ROTOR
(1) Attach the special tools to the knuckle and front hub.
(2) Secure the knuckle in a vise.
(3) Tighten the nut of the special tool and remove the hub
and rotor from the knuckle.
Caution1. Be sure to use the special tools.
2. If the hub and knuckle are disassembled by
striking them with a hammer, the bearing will
be damaged.8. REMOVAL OF WHEEL BEARING
(1) Crush the oil seal in two places to 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 hub by
using the special tool.
CautionBe careful that the hub will not fall down as the
wheel bearing inner race (outer side) is removed
from the hub.

NOTERemoval is easier if the outer side inner race removedLJfrom the hub is placed on the bearing and the wheel
bearing is then removed.
INSPECTIONM261GAC
lCheck the hub and brake disc mounting surfaces for galling
and contamination.
l Check the knuckle inner surface for galling and cracks.
l Check for defective bearing.
SERVICE POINTS OF REASSEMBLYMZBIHAO8. INSTALLATION OF WHEEL BEARING
(1) Fill the wheel bearing with multipurpose grease.
(2) Apply a thin coating of multipurpose grease to the
knuckle and bearing contact surfaces.
(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.
6. INSTALLATION OF OIL SEAL (HUB SIDE)
(1) Drive the oil seal (hub side) into the knuckle by using the
special tools until it is flush with the knuckle end
surface.
(2) Apply multipurpose grease to the lip of the oil seal and
_to the surfaces ot the 011 seal which contact the hub.d. ADJUSTMENT OF WHEEL BEARING STARTING
TORQUE
(I) Use the special tool to mount the hub assembly onto
the knuckle.
(2) Tighten the nut of the special tool to 200
- 260 Nm .(I45
- 188 ft.lbs.).
(3) Rotate the hub assembly in order to seat the bearing.llKO12
TSB Revision
(4) Measure the wheel bearing starting torque (hub starting
torque) by using the special tools.
Limit: 1.8 Nm (16
in.lbs.) or less
NOTEThe starting torque must be within the limit and, in
addition, the bearing must not feel rough when rotated.

REMOVAL AND INSTALLATIONRemoval steps(5) Measure to determine whether the end play of the hub
is within the specified limit or not.
Limit: 0.05 mm
(.002 in.)
(6) If the starting torque and hub end play are not within the
limit range while the nut is tightened to 200
- 260 Nm
(145
- 188 ft.lbs.), the bearing, hub and/or knuckle have
probably not been installed correctly. Repeat the dis-
assembly and assembly procedure.

Loosen the drive shaft nut while the vehicle is on the floor
with the brakes applied.
Caution
Do not apply vehicle load to the wheel bearing loosingthe drive shaft nut. If, however, vehicle load must be
applied to the bearing in moving the vehicle, temporari-
ly secure the wheel bearing by using the special tools,
MB990998-01, etc.
3. DISCONNECTION OF LOWER ARM BALL JOINT
Using the special tool, disconnect the lower arm ball joint
from the knuckle.
Caution1. Be sure to tie the cord of the special tool to the
nearby part.2. Loosen the nut but do not remove it.
5. DISCONNECTION OF TIE ROD END
Using the special tool, disconnect the tie rod end from the
knuckle.

(1) Using the special tool, remove the inner shaft assem-
bly, together with the seal plate, from the T.J. case.
NOTEPress the tool directly against the seal plate. The tool
under pressure will puncture and deform the seal plate,
and push out the inner shaft underneath.
(2) Use the special tool to remove the inner shaft from the
center bearing bracket.
11. REMOVAL OF CENTER BEARINGUse the special tools to remove the center bearing from the
center bearing bracket.
17. REMOVAL OF T.J. BOOT
/ 20. B.J. BOOT
(1) Wrap vinyl tape around the spline on the T.J. side of the
drive shaft so that the T.J. and B.J. boots are not
damaged when they are removed.
(2) Withdraw the T.J. and B.J. boots from the drive shaft.22.REMOVAL OF GREASE FROM B.J. ASSEMBLY
