4. INSPECT KEY INTERLOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure the resistance between ter-
minals 3 and 4.
Standard resistance: 12.5 ± 16.5 W
If the resistance value is not as specified, replace the solenoid.
(c) Apply battery positive voltage between the terminals 3
and 4. Check that an operation sound can be heard from
the solenoid.
If the solenoid does not operate, replace the solenoid.
5. INSPECT SHIFT LOCK CONTROL SWITCH
Check that there is continuity between terminals.

REASSEMBLY
1. ASSEMBLE DIFFERENTIAL CASE
(a) Coat the 2 side gear thrust washers and 2 pinion thrust
washers with ATF.
(b) Install the 2 side gears, 2 pinions and 4 thrust washers to
the case.
(c) Check the side gear backlash.
Measure the side gear backlash while pushing one pinion
gear toward the case.
Standard backlash:
0.05 ± 0.20 mm (0.0020 ± 0.0079 in.)
Referring to the table below, select thrust washers
which backlash is surely within the specified range.
Select washers of the same size for both sides.
Thrust washer thickness

0.95 mm (0.0374 in.)1.10 mm (0.0433 in.)
1.00 mm (0.0394 in.)1.15 mm (0.0453 in.)
1.05 mm (0.0414 in.)1.20 mm (0.0472 in.)
If the backlash is not within the specified range, install a thrust
washer of a different thickness.
(d) Using a pin punch and a hammer, install the straight pin.
(e) Stake the differential case.
2. INSTALL 2 TAPERED ROLLER BEARINGS
CAUTION:
A: The one which has bigger rollers
(The number of rollers is 22.)

POSITION VEHICLE ON WHEEL ALIGNMENT TES-
TER
Follow the specific instructions of the equipment manufacturer.
3. INSPECT CAMBER, CASTER AND STEERING AXIS
INCLINATION
Camber, caster and steering axis inclination:
Camber
Right±left error±0°26' ± 45' (±0.43° ± 0.75°)
45' (0.75°) or less
Caster
Right±left error1°02' ± 45' (1.03° ± 0.75°)
45' (0.75°) or less
Steering axis inclination
Right±left error9°52' ± 45' (9.87° ± 0.75°)
45' (0.75°) or less
If the caster and steering axis inclination are not within the spe-
cified values, after the camber has been correctly adjusted, re-
check the suspension parts for damaged and/or worn out parts.
4. ADJUST CAMBER
NOTICE:
After the camber has been adjusted, inspect the toe±in.
(a) Remove the front wheel.
(b) Remove the 2 nuts on the lower side of the shock absorb-
er.
