Measure with the vehicle unloaded (without passengers or a load).
Check the inspected areas again before adjusting the wheel alignment.
1) Inspect for the following.
1) Measure the buffer clearance and trim height.

25.9 mm { 1.02 in } |
Trim height (Reference value) |
119 mm { 4.7 in } |

1) Loosen the cam bolt lock nut.
2) Rotate the cam bolt and adjust the buffer clearance and trim height.

3) After adjusting the buffer clearance and trim height, tighten the lock nut to secure the lower link.
Tightening torque: 186 N・m { 19.0 kgf・m / 137 lb・ft }
1) Park the vehicle on a level surface.
2) Inspect the wheel alignment using an alignment device.
Note
3) Loosen the lower link cam bolt nut as necessary.
4) Adjust the caster and camber.
An adjust cam is fitted to either front or back end of the front suspension lower link. This allows for simultaneous adjustment of camber and caster angles.
Legend
The following illustration describes the camber and caster adjustment procedure.

Mark "A" at the intersection of camber measured angle value (solid line) and caster measured angle value (dotted line).
Mark "B" at the intersection of camber standard angle value (solid line) and caster standard angle value (dotted line).
Vertical distance between points A and B shows adjustment required for front cam.
Horizontal distance between points A and B shows adjustment required for rear cam.
In this case, the front cam may move in the plus direction 5 increments, and the rear cam may move in the plus direction 8 increments.
5) Final tighten the lower link cam bolt nut.

Toe-in measurement and adjustment should be performed with the vehicle parked on a flat plate.
If it is difficult to park on a flat plate, perform with the vehicle parked on a level floor.
1) Set the front wheel to the position for advancing straight forward.
2) Place the tip of the toe-in gauge in the center of the tire treads at a height equal to the center of the wheel shaft on the back of the left and right front wheels, and make a mark.
3) Measure distance 2 between the marks on the back of the front wheels.
4) Rotate the front wheels 180°.
5) Measure distance 1 between the left and right marks on the front of the vehicle.
6) Obtain the toe-in from the measured values.

1) Loosen the tie rod lock nut.
2) Rotate the tie rod to adjust the toe-in.
To keep the steering wheel in the center position, adjust by rotating both of the left and right tie rods only the same amount.

3) After adjusting the toe-in, tighten the lock nut to secure the tie rod.
Tightening torque: 98 N・m { 10.0 kgf・m / 72 lb・ft }
1) Adjust the wheel steering angle.
The wheel steering angle is not adjustable, but if there is significant left/right difference, inspect the suspension arm, knuckle, tie rod, etc., for damage.
If an abnormal condition is not found as a result of inspection, in the same way as the toe-in adjustment, turn the left and right tie rods the same amount to make the left and right steering angles roughly the same.
