3A-2 FRONT ALIGNMENT
Front End Alignment Inspection and
Adjustment
General Description
“Front End Alignment” refers to the angular relationship
between the front wheels, the front suspension attaching parts
and the ground.
Proper front end alignment must be maintained in order to
insure efficient steering, good directional stability and to
prevent abnormal tire wear.
The most important factors of front end alignment are wheel
toe-in, wheel camber and axle caster.
Camber:
This illustration shows a view from the front of the vehicle.
Camber is the vertical tilting inward or outward of the front
wheels. W hen the wheels tilt outward at the top, the camber is
positive (+). W hen the wheels tilt inward at the top, the camber
is negative (-). The amount of tilt measured in degrees from
the vertical is called the camber angle (1). If camber is extreme
or unequal between the wheels, improper steering and
excessive tire wear will result. Negative camber causes wear
on the inside of the tire, while positive camber causes wear to
the outside.
Caster:
This illustration shows a view from the side of the vehicle.
Caster (1) is the vertical tilting of the wheel axis either
forward or backward (when viewed from the side of the
vehicle). A backward tilt is positive (+) and a forward tilt is
negative (-). On the short and long arm type suspension
you cannot see a caster angle without a special instrument, but
if you look straight down from the top of the upper control arm
to the ground, the ball joints do not line up (fore and aft) when
a caster angle other than 0 degrees is present. W ith a positive
angle, the lower ball joint would be slightly ahead (toward the
front of the vehicle) of the upper ball joint center line.
Toe-in:
This illustration shows a view from the top of the vehicle.
Toe-in is the measured amount the front wheels are turned in.
The actual amount of toe-in is normally a fraction of a degree.
Toe-in is measured from the center of the tire treads or from
the inside of the tires. The purpose of toe-in is to insure parallel
rolling of the front wheels and to offset any small deflections of
the wheel support system which occurs when the vehicle is
rolling forward. Incorrect toe-in results in excessive toe-in and
unstable steering. Toe-in is the last alignment to be set in
the front end alignment procedure.

Notes:
1. Adjusting cam is at initial position (the hole & projection are upward as shown in a illustration) before a shim
adjustment.
2. Difference of caster shim front/rear thickness should be 3.6mm(0.142in) or less.
Overall thickness of caster shim and camber shim
should be 10.8mm(0.426in) or less.
3. Make a combination in a such a way that the number of shims is at a minimum.

6. Fully close the shutoff valve. Record the highest
pressures.
・ If the pressure recorded is within 9800-10300 kPa
(100-105 kg/cm
2/1422-1493psi), the pump is
functioning within its specifications.
・ If the pressure recorded is higher than 10300 kPa
(105 kg/cm
2/1493psi), the valve in the pump is
defective.
・ If the pressure recorded is lower than 9800 kPa
(100 kg/cm
2/1422psi), the valve or the rotating
assembly in the pump is defective.
7. If the pump pressures are within specifications, leave the valve open and turn (or have someone
else turn) the steering wheel fully in both directions.
Record the highest pressures and compare with the
maximum pump pressure recorded in step 6. If this
pressure cannot be built up at either side of the
power steering unit, the power steering unit is
leaking internally and must be replaced.
8. Shut the engine off, remove the testing gauge.
9. Reconnect the pressure hose, check the fluid level and make the needed repairs.
10. If the problem still exists, the steering and front suspension must be thoroughly examined.
Maintenance
The hydraulic system should be kept clean, the fluid
level in the reservoir should be checked at regula
r
intervals and fluid added when required. Refer to
Recommended Fluids and Lubricants in General
Information section for the type of fluid to be used and
the intervals for filling.
If the system contains some dirt, flush it as described in
this section. If it is exceptionally dirty, the pump must be
completely disassembled before further usage. (The
steering unit cannot be disassembled.)
All tubes, hoses, and fittings should be inspected for
leakage at regular intervals. Fittings must be tight. Make
sure the clips, clamps and supporting tubes and hoses
are in place and properly secured.
Power steering hoses and lines must not be twisted,
kinked or tightly bent. Air in the system will cause
spongy action and noisy operation. W hen a hose is
disconnected or when fluid is lost, for any reason, the
system must be bled after refilling. Refer to Bleeding the
Power Steering System in this section.
・ Inspect gear for looseness or damage.
・ Inspect hoses to insure they are not touching an
y
other parts of the vehicle.
・ Inspect fluid level and fill to the proper level.
Fluid Level
1. Run the engine until the power steering fluid
reaches normal operating temperature, about 55 °
C (130 °F), then shut the engine off.
2. Check the level of fluid in the reservoir.
3. If the fluid level is low, add power steering fluid as
specified in General Information to the proper level
and install the receiver cap.
4. W hen checking the fluid level after the steering system has been serviced, air must be bled from
the system. Refer to Bleeding the Power Steering
System in this section.
Bleeding the Power Steering System
W hen a power steering pump or unit has been installed,
or an oil line has been disconnected, the air that has
entered the system must be bled out before the vehicle
is operated. If air is allowed to remain in the powe
r
steering fluid system, noisy and unsatisfactory operation
of the system may result.
Bleeding Procedure
W hen bleeding the system, and any time fluid is added
to the power steering system, be sure to use only powe
r
steering fluid as specified in General Information.
1. Fill the pump fluid reservoir to the proper level and let the fluid settle for at least two minutes.
2. Start the engine and let it run for a few seconds. Do not turn the steering wheel. Then turn the engine
off.
3. Add fluid if necessary.
4. Repeat the above procedure until the fluid level remains constant after running the engine.
5. Raise and support the front end of the vehicle so that the wheels are off the ground.
6. Start the engine. Slowly turn the steering wheel right and left, lightly contacting the wheel stops.
7. Add power steering fluid if necessary.
8. Lower the vehicle, set the steering wheel at the straight forward position after turning it to its full
steer positions 2 or 3 times, and stop the engine.
9. Check the fluid level and refill as required.
10. If the fluid is extremely foamy, allow the vehicle to settle for a few minutes, then repeat the above
procedure.
Flushing the Power Steering System
1. Raise and support the front end of the vehicle off
the ground until the wheels are free to turn.
2. Remove the fluid return line at the pump inlet connector and plug the connector port on the pump.
Direct the line toward a large container to catch the
draining fluid.
3. W hile running the engine at idle, fill the reservoi
r
with new power steering fluid. Turn the steering
wheel in both directions. Do not contact or hold the
steering wheel to the wheel stops. This will cause
the pump to go to pressure relief mode, which ma
y
cause a sudden fluid overflow at the reservoir.
