Check vehicle posture.

CAMBER INSPECTION

Measure camber of both right and left wheels with a suitable
alignment gauge and adjust in accordance with the following
procedures.

5.

Push vehicle slowly ahead to rotate wheels 180 degrees (1/2
turn).
If wheels have rotated more than 180 degrees (1/2 turn), try the
above procedure again from the beginning. Never push vehicle
backward.
