1. WHEEL ARCH HEIGHT

1. Park the vehicle on a level surface.

2. Empty the vehicle so that it is at “curb weight”.

NOTE:

Empty the trunk or luggage room, load the spare tire, jack and service tools, and fill up the fuel tank.

3. Set the steering wheel in a straight-ahead position, and stabilize the suspension by moving the vehicle in a straight line for 5 m (16 ft) or more.

4. Suspend a thread from the wheel arch (point “A” in the figure below) and affix at a position directly above the center of wheel.

5. Measure the distance between the point “A” and the center of wheel.

2. CAMBER

1. Place the front wheel on the turning radius gauge.

NOTE:

Make sure the ground contact surfaces of the front and rear wheels are at the same height.

2. Set the adapter into the center of wheel, and then set the wheel alignment gauge.

4. STEERING ANGLE

1. Place the vehicle on turning radius gauge.

2. While depressing the brake pedal, turn the steering wheel fully to the left and right.

3. With the steering wheel held at each fully turned position, measure both the inner and outer wheel steering angles.

5. FRONT WHEEL TOE-IN

Toe-in: Inspection value

0±3 mm (0.00±0.12 in)

1. Set the toe-in gauge in the position at wheel axis center height behind the right and left front tires.

2. Place a mark at the center of both left and right tires, and measure distance “A” between the marks.

3. Move the vehicle forward to rotate the tires 180°.

NOTE:

Be sure to rotate the tires in the forward direction.

4. Measure the distance “B” between the left and right marks. Find toe-in using the following calculation:

A − B = Toe-in

6. REAR WHEEL TOE-IN

Refer to the FRONT WHEEL TOE-IN for rear toe-in inspection procedures. Wheel Alignment > INSPECTION

Toe-in: Inspection value

3±3 mm (0.12±0.12 in)

7. THRUST ANGLE

1. Park the vehicle on a level surface.

2. Move the vehicle 3 — 4 meters (10 — 13 feet) straight forward.

3. Draw the center of loci for both the front and rear axles.

4. Measure distance “L” between the center lines of the axle loci.

Thrust angle: Inspection value

0°±30'

Less than 30' when “L” is 23 mm (0.9 in) or less
