| Title: ALIGNMENT / HANDLING DIAGNOSIS: FRONT WHEEL ALIGNMENT: ADJUSTMENT (2008 Sequoia) | ||
ADJUSTMENT
NOTICE:
For vehicles equipped with VSC, if the 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:
- Disconnect the negative battery terminal for more than 2 seconds.
- Reconnect the negative battery terminal.
- Perform zero point calibration of the yaw rate and deceleration sensor and test mode inspection.
HINT:
1. INSPECT TIRE
2. MEASURE VEHICLE HEIGHT
NOTICE:
Before inspecting the wheel alignment, adjust the vehicle height to the specification.
|
(a) Press down on the vehicle several times to stabilize the suspension, and then measure the vehicle height. Standard Vehicle Height (Unloaded Vehicle):
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 drive shaft center D: Ground clearance of the rear lower arm No. 1 adjusting cam bolt 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 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):

5. 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):
|
6. INSPECT TOE-IN
(a) Bounce the vehicle up and down at the corners to stabilize the suspension and inspect the toe-in.
