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.

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.

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.

llE526(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) The drive shaft
(R.H.) is removed 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.
Insert 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.
INSPECTIONN02QCAEl 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.
l Check the operation of the center bearing.

REAR AXLE - Troubleshooting3-7
Symptom
NOTE
1 Probable cause1 Remedy
In addition to a malfunction of the differential carrier components, abnormal noise can also be caused by the universal
joint of the propeller shaft, the axle shafts, the wheel bearings, etc. Before disassembling any parts, take all
possibilities into consideration and confirm the source of the noise.

Noise from the engine, muffler vibration, transaxle, propeller shaft, wheel bearings, tires, body, etc., is easily mistaken
as being caused by malfunctions in the differential carrier components. Be extremely careful and attentive whenperforming the driving test, etc.
Test methods to confirm the source of the abnormal noise include:coasting acceleration, constant speed driving,
raising the rear wheels on a jack, etc. Use the method most appropriate to the circumstances.
