Make sure the steering wheel is straight when adjusting the front wheel toe.
HINT: The Steering Wheel Offset Gauge/Centering Tape (or masking tape) can be used to center the
steering wheel while standing outside of the car during the alignment process.

4. Road test to confirm the steering wheel is straight (not off-center 2 mm or more).
5. Remove the Steering Wheel Offset Gauge (Centering Tape).
6. Attach to the Repair Order a copy of the alignment machine printout showing the BEFORE and AFTER
alignment readings. Write on the print-out the amount of steering wheel off-center (in millimeters) before
and after the alignment.
7. If necessary, use C-III plus to adjust the Steering Angle Sensor.


Refer to the appropriate Electronic Service Manual to determine if this adjustment is necessary.

HINT: If wheel alignment is performed, attach a copy of the alignment machine print-out showing the
BEFORE and AFTER alignment readings.

Appendix
Relationship of alignment settings to vehicle pull

Camber:
The camber thrust direction will be to the side with the
“most positive” camber setting.
EXAMPLE: If the left camber is significantly higher (more
positive) than the right, the vehicle will tend to drift or pull
to the left.

Figure 5

Caster:
The caster thrust direction will be to the side with “most
negative” caster setting.
EXAMPLE: If the left caster is significantly higher (more
positive) than the right, the vehicle will tend to drift or pull
to the right.

Figure 6

Thrust Angle:
The rear Thrust Angle should be close to 0. Excessive
thrust angle may cause the steering wheel to be offcenter.

Appendix (continued)
Caster camber adjustment
There are no provision provided for adjusting caster and camber on many Infiniti models, but some adjustment
may be achieved by the following methods:
Strut Suspension Camber Adjustment
a. Raise the vehicle and remove the front tires.
b. Loosen the upper steering knuckle bolts and nuts.
c. Adjust the camber by moving the steering knuckle within the range of the free play of the bolts.
d. Tighten the bolts to the specified torque (refer to the Electronic Service Manual).
e. Reinstall the front wheels and lower the vehicle. Jounce (bounce) the front and rear of the vehicle
several times to stabilize the suspension.
Strut Suspension Camber & Caster Adjustment
a. Raise the vehicle and remove the front wheels.
b. Loosen the upper strut mount bolts.
c. Adjust camber and caster by moving the upper strut mount within the range of the free play of the bolts.
d. Tighten the bolts to the specified torque (refer to the Electronic Service Manual).
e. Reinstall the front wheels and lower the vehicle. Jounce (bounce) the front and rear of the vehicle
several times to stabilize the suspension.
Cradle Camber & Caster Adjustment
a. Loosen all of the cradle bolts. (DO NOT remove any of these bolts.)
b. Adjust camber and caster by moving the cradle within the range of the free play of the bolts. (Side to
side movement will change Camber and SAI; Fore-Aft movement will change Caster).
c. Tighten the bolts to the specified torque (refer to the Electronic Service Manual).
d. Jounce (bounce) the front and rear of the vehicle several times to stabilize the suspension.

SPECIAL TOOLS


Additional tools are available from Tech•Mate online: www.techmatetools.com, or by phone:
1-833-397-3493.
HINT: When ordering, keep in mind that the tool part number prefix has changed from “J” to “NI”. For
example, J-49286-3 is now NI-49286-3.

Steering Wheel Offset Gauge (Centering Tape) – Tool # J-49286-3
(New part number: NI-49286-3)

The Steering Wheel Offset Gauge (Centering Tape) is
a set of one-time use stickers that are attached to the
steering wheel and the steering column cover.

Tool Use
Turn/adjust the steering wheel to the straight position
(spokes of steering wheel are straight across).

Figure 8

Attach the sticker with numbers on the steering
column cover.
Attach the arrow sticker on the steering wheel. Make
sure the arrow lines up with the 0 (zero) mark.
When you road test the vehicle you can read how
many millimeters the steering wheel is off-center.

Figure 9

HINT: If stickers are not available, use a piece of
masking tape on the steering wheel and on the
steering column. Mark where the steering wheel is
centered and a maximum mark to either side (refer to
page 8 for vehicle maximum allowable offset).

Road Crown Gauge (Tilt Indicator) – Tool # J-49286-2
(New part number: NI-49286-2)
The Road Crown Gauge (Tilt Indicator) measures the
amount of road crown in degrees.
The suction cup is used to attach the Road Crown
Gauge (Tilt Indicator) to a secure spot on the vehicle
dash.

Tool Use
Before the road test, calibrate the gauge.

Figure 11

HINT: The gauge must be calibrated with the same
weight in the vehicle as there will be during the road
test. For example, if you plan to have an assistant in the
vehicle during the road test, calibrate the gauge while
both of you are sitting in the vehicle.
There are two ways to calibrate the gauge:


Preferred method: Park the vehicle on a level
surface, such as an alignment rack and
calibrate the gauge by moving the gauge until
the ball is on the zero mark.
Figure 12



If you do not have a perfectly flat level surface:
a. Park the vehicle on a reasonable flat level surface and note the gauge reading.
b. Turn the vehicle 180 degrees so the vehicle is in the same spot but facing the opposite direction
and note the gauge reading.
c. Move/calibrate the gauge so it reads half the difference between the two readings.
For example, if the first reading is -1 and the second reading (after moving the vehicle) is +3, half
way between is +1.
1st reading -1
-6

2nd reading +3
