Wheel Alignment
Before checking rear wheel alignment, be sure to make a preliminary inspection.
PRELIMINARY INSPECTION
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel runout.
3. Check rear wheel bearings for looseness.
4. Check rear suspension for looseness.
5. Check that rear shock absorbers work properly.
6. Check vehicle posture (Unladen)
CAMBER

^ Measure camber of both right and left wheels with a suit-able alignment gauge and adjust in accordance with the following procedures.

If camber is not within specification, adjust by turning the adjusting bolt.
1. Turn the adjusting bolt to calibrate.
Camber changes about 5' with each graduation of the adjusting bolt.
2. Tighten to the specified torque.
81 - 100 Nm (8.2 - 10.2 kg-m, 60 - 73 ft. lbs.)
TOE-IN
Measure toe-in using following procedure. If out of specification, inspect and replace any damaged or worn rear suspension parts.
WARNING:
^ Always perform following procedure on a flat surface.
^ Make sure that no person is in front of the vehicle before pushing it.
1. Bounce rear of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).

3. Put a mark on base line of the tread (rear side) of both tires at the same height of hub center. This mark is a measuring point.

4. Measure distance "A" (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 180° (1/2 turn).
If the wheels have rotated more than 180° (1/2 turn), try the above procedure again from the beginning. Never push vehicle backward.
6. Measure distance "B" (front side).

7. Adjust toe-in by turning adjusting bolts. Toe changes about 1.5 mm (0.059 inch) [One side] with each graduation of the adjusting bolt.
8. Tighten to the specified torque.
70 - 90 Nm (7.1 - 9.2 kg-m, 52 - 66 ft. lbs.)
