REAR WHEEL ALIGNMENT
PRE-INSPECTION
1. Check the tire inflation and bring to the recom-
mended pressure.
2. Inspect the wheel and tire runout.
3. The vehicle must be on level ground and have no
luggage or passenger load.
4. Check that the suspension is correctly adjusted.
5. The difference in height between the left and right
sides from the center of the wheel to the fender
rim should be within 10 mm (0.39 in).
Caution
a) Front and rear wheel alignments should be
checked simultaneously. If adjustment is
made to either the front or rear wheels,
recheck the alignment, particularly toe-in,
on all other wheels.
b) Check and adjust the steering angle trans-
fer shaft after adjusting the rear wheel align-
ment. (Refer to Section 10.)
TOE-IN
Inspection
1. Raise the rear of the vehicle until the wheels clear
the ground.
2. Turn the wheels by hand, mark a line in the center
of each tire tread using a scribing block.
3. Lower the vehicle.
4. Measure the distance between the marked lines
at the front and rear of the wheels.
Toe-in
0 ± 3 mm (0 ±0.12 in) 2WS
3 ± 3 mm (0.12 ±0.12 in) 4WS
Adjustment (2WS)
1. Loosen the adjusting rod lock nuts, then adjust the
toe-in.
2. To increase the toe-in, turn the adjusting rods as
follows:
Right rod — Turn counterclockwise
Left rod — Turn clockwise
To decrease the toe-in, turn the adjusting rods as
follows:
Right rod — Turn clockwise
Left rod — Turn counterclockwise
Caution
a) Both the left and right rods must be adjust-
ed by the same amount.
b) One turn of the adjusting rod (both sides)
changes the toe-in by about 11.6 mm (0.46
in).
3. Tighten the adjusting rod lock nuts to the speci-
fied torque.
Tightening torque:
55—80 N-m (5.6—8.2 m-kg, 41—59 ft-lb)

16 OUTLINE
Safety Precautions
1. The R-12 liquid refrigerant is highly volatile. A drop
of it on the skin of your hand could result in local-
ized frostbite. When handling the refrigerant, be
sure to wear gloves.
2. If the refrigerant splashes into your eyes, wash
them with clean water immediately. It is standard
practice to wear goggles or glasses to protect your
eyes, and gloves to protect your hands.
3. The R-12 container is a highly pressurized vessel.
Never leave it in a hot place, and check to be sure
that the temperature where it is stored is below
52°C (126°F).
4. A halide leak detector is often used to check the
system for refrigerant leakage. Remember that
R-12, upon coming into contact with flame (this de-
tector burns like propane to produce a small flame),
produces phosgene, a toxic gas.

Refrigerant Container Service Valve
1. Before connecting the valve to the refrigerant con-
tainer, turn the handle fully counterclockwise.
2. Turn the disc counterclockwise until it reaches its
highest position.
3. Connect the center hose to the valve fitting. Turn
the disc fully clockwise by hand.
4. Turn the handle clockwise to make a hole in the
sealed tap.
5. Turn the handle fully counterclockwise to fill the
center hose with air. Do not open the high- and
low-pressure manual valves.
6. Loosen the center hose nut connected to the cen-
ter fitting of the manifold gauge.
Allow air to escape for a few seconds, then tight-
en the nut.
