Aiming AdjustmentAKS007CT
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.

Keep all tires inflated to correct pressure.

Place vehicle on level ground.

See that vehicle is unloaded (except for full levels of coolant, engine oil and fuel, and spare tire, jack, and
tools). Have the driver or equivalent weight placed in driver seat.
Adjust aiming in the vertical direction by turning the adjusting screw.
1. Set the distance between the screen and the center of the fog
lamp lens as shown at left.
2. Turn front fog lamps ON.
3. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is 100 mm (4 in) below the height of
the fog lamp centers as shown at left.

When performing adjustment, if necessary, cover the head-
lamps and opposite fog lamp.

CAUTION:

Secure steering gear assembly with a vise, using copper
plates or something similar to prevent it from being dam-
aged. Do not grip cylinder with a vise.

Before performing disassembly, clean steering gear assem-
bly with kerosene. Be careful not to bring any kerosene into
contact with the discharge and return port connectors.
DISASSEMBLY
1. Remove cylinder tubes from gear housing assembly.
2. Remove rear cover cap from gear housing assembly.
3. Measure adjusting screw height from gear housing assembly,
then loosen adjusting screw.
CAUTION:

Do not turn adjusting screw more than twice.

Replace steering gear assembly when adjusting screw is
removed or more than twice.
4. Use a rear cover wrench (SST) to remove rear cover from sub-
gear assembly.
5. Remove O-ring with a flat-bladed screwdriver, and pull out rear
cover.
6. Remove sub-gear assembly from gear housing assembly.
CAUTION:
In order to protect oil seal from any damage, pull sub-gear
assembly out straightly.
7. Loosen lock nut of outer socket, and remove outer socket.
8. Remove boot clamps of the small diameter side and the large
diameter side, then remove boot.

9. Use a rear cover wrench (SST), install rear cover to gear housing assembly.
10. Confirm projection on rear cover cap nearly fit with marking position on gear housing assembly.

alent. Refer to GI-48
) to the thread of adjusting screw to the
adjusting screw height from gear housing assembly. The adjust-
ing screw height is the same as it was measured in the overhaul
in advance.
12. Rotate pinion ten times whole range of rack so that parts get to
fit with each other.
13. Measure pinion rotating torque within from –180° to +180°,
make preload gauge (SST) and torque adapter (SST) in rack
neutral position, then hold preload gauge (SST) at maximum
torque.
14. After loosening adjusting screw once, tighten it again with torque
of 5.4 N·m (0.55 kg-m, 48 in-lb). After that loosen it within 20° to
40°.
15. Measure pinion rotating torque with torque adapter (SST) and
preload gauge (SST), then confirm whether it's reading is within
the specified value. If the reading is not within the specified
value, readjust screw angle with adjusting screw. Change gear
assembly to new one, if the reading is still not within the speci-
fied value or the rotating torque of adjusting screw is less than 5
N·m (0.51 kg-m, 44 in-lb).
16. Turn pinion fully to the end of the left with inner socket to gear housing assembly.
17. Set dial gauge to rack as shown in the figure. Measure vertical
movement of rack when pinion is turned counterclockwise with
torque of 19.6 N·m (2.0 kg-m, 14 ft-lb). Check reading is within
the specified value. If reading is outside of the specification,
readjust screw angle with adjusting screw. If reading is still out-
side of specification, or if the rotating torque of adjusting screw is
less than 5 N·m (0.51 kg-m, 44 in-lb), replace steering gear
assembly.

5. Adjust clearance between rear face of side gear and thrust
washer by selecting side gear thrust washer. Refer to RFD-31,
"AVAILABLE PINION HEIGHT ADJUSTING WASHERS" .
Use two feeler gauges to prevent leaning of side gear as show-
ing figure.
SIDE BEARING PRELOAD
A selection of carrier side bearing adjusting washers is required for successful completion of this procedure.
1. Make sure all parts are clean. Also, make sure the bearings are
well lubricated with gear oil.
2. Place the differential case, with side bearings and bearing races
installed, into gear carrier.
3. Insert left and right original side bearing adjusting washers in
place between side bearings and carrier.
4. Install the side bearing caps in their correct locations and torque
the bearing cap retaining bolts.
5. Turn the carrier several times to seat the bearings.Clearance between side gear thrust washer and dif-
ferential case

6. Measure the turning torque of the carrier at the drive gear retain-
ing bolts with a spring gauge, J-8129.
7. If the turning torque is not within the specifications, correct the
torque as follows:

If the turning torque is less than the specified range, install
washers of greater thickness.

If the turning torque is greater than the specification, install
thinner washers.

See the SDS section for washer dimensions and part num-
bers.
8. Record the total amount of washer thickness required for the
correct carrier side bearing preload.
9. Remove the carrier from the final drive housing. Save the
selected washers for later use during the assembly of the final
drive unit.
PINION GEAR HEIGHT
1. Make sure all parts are clean and that the bearings are well
lubricated.
2. Assemble the pinion gear bearings into the differential shim
selector tool, J34309.

Pinion front bearing; make sure the J34309-3 pinion front bear-
ing seat is secured tightly against the J34309-2 gauge anvil.
Then turn the pinion front bearing pilot, J34309-5, to secure the
bearing in its proper position.

Pinion rear bearing; the pinion rear bearing pilot, J34309-8, is
used to center the pinion rear bearing only. The pinion rear bear-
ing locking seat, J34309-4, is used to lock the bearing to the
assembly.Specification

Installation of J34309-9 and J34309-16; place a suitable 2.5 mm (0.098 in) thick plain washer between
J34309-9 and J34309-16. Both surfaces of J34309-9 and J34309-16 must be parallel with a clearance of
2.5 mm (0.098 in).
3. Install the pinion rear bearing inner race into the final drive hous-
ing. Then place the pinion preload shim selector tool, J34309-1,
gauge screw assembly.
4. Assemble the pinion front bearing inner race and the J34309-2
gauge anvil. Assemble them together with the J34309-1 gauge
screw in the final drive housing. Make sure that the pinion height
gauge plate, J34309-16, will turn a full 360 degrees. Tighten the
two sections together by hand.
5. Turn the assembly several times to seat the bearings.
6. Measure the turning torque at the end of the J34309-2 gauge
anvil using torque wrench J-25765A.
