Nissan Sentra Service Manual: Wheel alignment
Inspection
PRELIMINARY INSPECTION
WARNING:
Always adjust the wheel alignment with the vehicle on a flat surface.
NOTE:
If the wheel alignment is out of specification, inspect and replace any
damaged or worn rear suspension parts
before making any adjustments.
- Check and adjust the wheel alignment with the vehicle under unladen
conditions. “Unladen conditions”
means that the fuel, engine coolant, and lubricants are full; the spare
tire, jack, hand tools and mats are in
designated positions.
- Check the tires for incorrect air pressure and excessive wear.
- Check the wheels for run out and damage. Refer to WT-46, "Inspection".
- Check the wheel bearing axial end play. Refer to FAX-6, "Inspection".
- Check the shock absorbers for leaks or damage
- Check each mounting point of the suspension components for any excessive
looseness or damage.
- Check each link, arm, and the suspension member for any damage.
- Check the vehicle height. Refer to FSU-23, "Wheelarch Height (Unladen*)".
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 FSU-23, "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" method if you are using sensor-type
alignment equipment.
- Follow all instructions for the alignment machine you're using for
more information.
CAMBER, CASTER AND KINGPIN INCLINATION ANGLES INSPECTION
- Camber, caster, kingpin inclination angles cannot be adjusted.
- Before inspection, set the front wheels onto a turning radius gauge. Set
the rear wheels onto a pad that has
the same height so the vehicle will remain horizontal.
TOTAL TOE-IN INSPECTION
Measure the total toe-in using the following procedure.
WARNING:
- Always perform the following procedure on a flat surface.
- Make sure that no person is in front of vehicle before pushing
it.
- Bounce the front of vehicle up and down to stabilize the vehicle height
(posture).
- Push on the rear wheel to move the vehicle straight ahead about 5 m (16
ft).
- Put a mark on 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 on 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 vehicle backward.
- Measure the distance (B) from the front side.
![](images/books/349/29/index248.gif)
- Use the formula below to calculate total toe-in.
Total toe-in : A - B
Total toe-in specification : Refer to FSU-23, "Wheel
Alignment (Unladen*1)".
- If the total toe-in is outside the specification, adjust the total
toe-in. Refer to FSU-7, "Adjustment".
Adjustment
TOTAL TOE-IN
Loosen the steering outer socket. Adjust the length using the steering inner
socket.
Toe-in : Refer to FSU-23, "Wheel Alignment (Unladen*
1)".
CAUTION:
- Always evenly adjust both toe-in alternately and adjust the
difference between the left and right to
the standard.
- Always hold the steering inner socket when tightening the steering
outer socket.
