ADJUSTMENT
NOTE: For vehicles equipped with VSC, if wheel alignment has been adjusted, and if suspension or underbody components have been removed/installed or replaced, be sure to perform the following initialization procedure in order for the system to function normally:
1. Check that the steering wheel is in the centered position.
2. Disconnect the negative battery terminal for more than 2 seconds.
3. Reconnect the negative battery terminal.
4. Perform zero point calibration of the yaw rate and deceleration sensor and test mode inspection Programming and Relearning.
1. INSPECT TIRE

Standard vehicle height (unloaded vehicle):
for Regular Cab of Standard Deck
Standard vehicle height (unloaded vehicle):
for Regular Cab of Long Deck
* for 5 leaf spring
Standard vehicle height (unloaded vehicle):
for Double Cab of Standard Deck
Standard vehicle height (unloaded vehicle):
for Double Cab of Long Deck
Standard vehicle height (unloaded vehicle):
for CrewMax of standard deck
: for 5 leaf spring
Measuring points:
A
Ground clearance of the front drive shaft center
B
Ground clearance of the front adjusting cam bolt center
C
Ground clearance of the rear axle shaft center
D
Ground clearance of the leaf spring front side bushing center
If the vehicle height is not as specified, adjust the height by pressing down on the vehicle several times to stabilize the suspension.
3. INSPECT TOE-IN
(a) Bounce the vehicle up and down at the corners to stabilize the suspension and inspect the toe-in.
Standard toe-in (unloaded vehicle):
for Regular Cab of Standard Deck
Standard toe-in (unloaded vehicle):
for Regular Cab of Long Deck
* for 5 leaf spring
Standard toe-in (unloaded vehicle):
for Double Cab of Standard Deck
Standard toe-in (unloaded vehicle):
for Double Cab of Long Deck
Standard toe-in (unloaded vehicle):
for CrewMax of standard deck
* for 5 leaf spring
If the toe-in is not as specified, adjust it at the rack ends.
4. ADJUST TOE-IN
(a) Release the rack boot set clips.
(b) Loosen the tie rod end lock nuts.
(c) Turn the right and left rack ends by an equal amount to adjust the toe-in to the center value.
(d) Check that the length of the right and left rack ends are approximately the same.
Standard difference:
0 +/-1 mm (0 +/-0.0394 in.) or less
(e) Tighten the tie rod end lock nuts.
Torque: 69 Nm (704 kgf-cm, 51 ft-lbf)
(f) Place the boots on the seats and install the clips.
HINT: Make sure that the boots are not twisted.
5. INSPECT WHEEL ANGLE
(a) Turn the steering wheel to the left and right full lock positions, and measure the turning angle.
Standard wheel angle (unloaded vehicle):
for Regular Cab of Standard Deck
Standard wheel angle (unloaded vehicle):
for Regular Cab of Long Deck
* for 5 leaf spring
Standard wheel angle (unloaded vehicle):
for Double Cab of Standard Deck
Standard wheel angle (unloaded vehicle):
for Double Cab of Long Deck
Standard wheel angle (unloaded vehicle):
for CrewMax of standard deck
* for 5 leaf spring
6. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION
(a) Install the camber-caster-kingpin gauge or place the front wheels on the center of the wheel alignment tester.
(b) Inspect the camber, caster and steering axis inclination.
Standard camber inclination (unloaded vehicle):
for Regular Cab of Standard Deck
Standard camber inclination (unloaded vehicle):
for Regular Cab of Long Deck
* for 5 leaf spring
Standard camber inclination (unloaded vehicle):
for Double Cab of Standard Deck
Standard camber inclination (unloaded vehicle):
for Double Cab of Long Deck
Standard camber inclination (unloaded vehicle):
for CrewMax of standard deck
* for 5 leaf spring
Standard caster inclination (unloaded vehicle):
for Regular Cab of Standard Deck
Standard caster inclination (unloaded vehicle):
for Regular Cab of Long Deck
* for 5 leaf spring
Standard caster inclination (unloaded vehicle):
for Double Cab of Standard Deck
Standard caster inclination (unloaded vehicle):
for Double Cab of Long Deck
Standard caster inclination (unloaded vehicle):
for CrewMax of standard deck
* for 5 leaf spring
Standard steering axis inclination (unloaded vehicle):
for Regular Cab of Standard Deck
Standard steering axis inclination (unloaded vehicle):
for Regular Cab of Long Deck
* for 5 leaf spring
Standard steering axis inclination (unloaded vehicle):
for Double Cab of Standard Deck
Standard steering axis inclination (unloaded vehicle):
for Double Cab of Long Deck
Standard steering axis inclination (unloaded vehicle):
for CrewMax of standard deck
* for 5 leaf spring
7. ADJUST CAMBER AND CASTER
HINT: After the camber has been adjusted, inspect the toe-in.
(a) Loosen the toe adjusting cam bolt and camber adjusting cam nut.
(b) Turn the toe adjusting cam and camber adjusting cam in both directions, and adjust the camber and caster to the center value.
HINT: The camber and caster should be as close as possible to the center value.
(c) Read the adjustment chart (example).
(1) Find the wheel alignment standard value applicable for the particular model.
(2) Mark the selected standard value on the adjustment chart.
Standard value (reference):
(3) Mark the alignment value measured when the vehicle is unloaded on the adjustment chart.
Measured value (reference):
(4) As shown in the chart, read the distance from the marked point to 0, and adjust the front and/ or rear adjusting cams accordingly.
Amount to turn adjusting cams (by gradation):
8. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
NOTICE:
- Some systems need to be initialized after the cable is reconnected Repair Instruction - Initialization.
- After the ignition switch is turned OFF, the navigation system requires approximately 90 seconds to record various types of memory and settings. As a result, after turning the ignition switch OFF, wait 90 seconds or more before disconnecting the cable from the negative (-) battery terminal.
9. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
NOTE: Some systems need to be initialized after the cable is reconnected Repair Instruction - Initialization.
10. PERFORM YAW RATE AND DECELERATION SENSOR ZERO POINT CALIBRATION
(a) Perform the yaw rate and deceleration sensor zero point calibration Programming and Relearning.
11. CHECK STEERING ANGLE SENSOR ZERO POINT CALIBRATION
(a) Check the steering angle sensor zero point calibration C1290.
