Nissan Sentra Service Manual: Wheel alignment
Inspection
DESCRIPTION
Measure the wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricants are
full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY
Check the following:
- Tires for improper air pressure and wear.
- Road wheels for runout. Refer to WT-46, "Inspection".
- Wheel bearing axial end play. Refer to RAX-5, "Inspection".
- Shock absorber operation.
- Each mounting part of suspension for looseness and deformation.
- Rear suspension beam for cracks, deformation, and other damage.
- Vehicle height (posture).
GENERAL INFORMATION AND RECOMMENDATIONS
- A Four-Wheel Thrust Alignment should be performed.
- This type of alignment is recommended for any NISSAN vehicle.
- The four-wheel “thrust” process helps ensure that the vehicle is
properly aligned and the steering wheel
is centered.
- The alignment machine itself should be capable of accepting any NISSAN
vehicle.
- The alignment machine should be checked to ensure that it is level.
- Make sure the alignment machine is properly calibrated.
- Your alignment machine should be regularly calibrated in order to give
correct information.
- Check with the manufacturer of your specific alignment machine for their
recommended Service/Calibration
Schedule.
THE ALIGNMENT PROCESS
IMPORTANT:
Use only the alignment specifications listed in this
Service Manual. Refer to RSU-15, "Wheel
Alignment (Unladen*1)".
- When displaying the alignment settings, many alignment machines use
“indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
- The alignment specifications programmed into your alignment machine that
operate these indicators
may not be correct.
- This may result in an ERROR.
- Most camera-type alignment machines are equipped with both "Rolling
Compensation" method and
optional "Jacking Compensation" method to "compensate" the alignment targets
or head units.
"Rolling Compensation" is the preferred method.
- If using the "Rolling Compensation" method, after installing the
alignment targets or head units, push or
pull on the rear wheel to move the vehicle. Do not push or pull the vehicle
body.
- If using the "Jacking Compensation" method, after installing the
alignment targets or head units, raise
the vehicle and rotate the wheels 1/2 turn both ways.
NOTE:
Do not use the "rolling compensation" if you are using sensor-type
alignment equipment.
- Follow all instructions for the alignment machine you're using for
more information.
CAMBER INSPECTION
- Measure camber of both right and left wheels with a suitable alignment
gauge.
Camber : Refer to RSU-15, "Wheel Alignment
(Unladen*1)".
- If it is out of the specification value, inspect and replace any damaged
or worn rear suspension parts.
TOTAL TOE-IN INSPECTION
Measure the total toe-in using following procedure. If it is out of the
specification, inspect and replace any
damaged or worn rear suspension parts.
WARNING:
- Always perform the following procedure on a flat surface.
- Make sure that no person is in front of the vehicle before
pushing it.
- Bounce the rear of the vehicle up and down to stabilize the vehicle
height (posture).
- Push the rear wheel to move the vehicle straight ahead about 5 m (16
ft).
- Put a mark on the base line of the tread (rear side) of both tires
at the same height of hub center. These are measuring points.
- Measure the distance (A) from the rear side.
- Push the rear wheel to move the vehicle slowly ahead and to
rotate the wheels 180 degrees (1/2 turn).
CAUTION:
If the wheels have rotated more than 180 degrees (1/2 turn),
try the above procedure again from the beginning. Do not
push the vehicle backward.
- Measure the distance (B) from the front side.
Total toe-in : Refer to RSU-15, "Wheel Alignment
(Unladen*1)".
