5. If ``AIR BAG'' warning lamp operates as shown in No. 1 in
chart above, turn ignition switch ``OFF'' to reset from Diag-
nosis mode to User mode and to erase the memory of the
malfunction. Then go to step 6.
If ``AIR BAG'' warning lamp operates as shown in No. 2 or
No. 3 in chart above, the malfunctioning part is not repaired
completely, or another malfunctioning part is detected. Go to
DIAGNOSTIC PROCEDURE 6, page RS-37, and repair mal-
functioning part completely.
6. Turn ignition switch ``ON''. ``AIR BAG'' warning lamp operates
in User mode. Compare ``AIR BAG'' warning lamp operation
to the chart below.
NOTE:
If switching Diagnosis mode to User mode is required while
malfunction is being detected, turn ignition switch from
``OFF'' to ``ON''. Then press driver's door switch at least 5
times within 7 seconds after turning ignition switch ``ON''.

Removal
lBefore removing the rear axle, disconnect the ABS
wheel sensor from the assembly. Then move it away
from the axle. Failure to do so may result in damage to
the sensor wires and the sensor becoming inoperative.
lWheel bearing does not require maintenance.
lIf growling noise is emitted from wheel bearing during
operation, replace wheel bearing assembly.
lIf the wheel bearing assembly is removed, it must be
renewed. The old assembly must not be re-used.
1. Disconnect parking brake cable and brake tube.
2. Remove nuts securing wheel bearing cage with baffle plate.
3. Draw out axle shaft with Tool.
When drawing out axle shaft, be careful not to damage oil
seal.
4. Remove case shim and case seal.
Ð 2WD and 4WD models without ABS Ð
5. Remove O-ring. Ð 4WD models with ABS Ð
6. Remove oil seal.
Do not reuse oil seal once it is removed.
Always install new one.
7. Remove ABS sensor rotor. Ð 4WD models with ABS Ð
8. Unbend lock washer with a screwdriver.

After installing new oil seal, coat sealing lip with multi-pur-
pose grease.
9. Apply recess of axle case end with multi-purpose grease.
10. Apply gear oil to the spline of axle shaft. Coat seal surface
of axle shaft with multi-purpose grease (as shown left).
11. Adjust axial end play.
a. Select end shims.
Standard thickness: 1.5 mm (0.059 in)
Axle case end shim: Refer to SDS, RA-15.
Do not insert end shims between case seal and bearing
cage.
b. Insert axle shaft with Tool as a guide.
When inserting axle shaft, be careful not to damage oil seal.
c. Measure end play of axle shaft.
Axial end play:
Servicing one side axle
0.02 - 0.15 mm (0.0008 - 0.0059 in)
Servicing both side axles
On first axle (right or left)
0.30 - 0.90 mm (0.0118 - 0.0354 in)
