NOTICE:
• Before inspecting the wheel alignment, adjust
the vehicle height to the specified value.
• Be sure to perform measurement on a level
surface.
• If it is necessary to go under the vehicle for
measurement, confirm that the parking brake
is applied and the vehicle is secured with
chocks.

3. INSPECT TOE-IN
(a) Bounce the vehicle up and down at the corners to
stabilize the suspension.
(b) Release the parking brake and move the shift lever
to the neutral position.
(c) Push the vehicle straight ahead approximately 5 m
(16.4 ft). (*1)
(d) Put tread center marks on the rearmost points of the
front wheels and measure the distance between the
marks (dimension B).
(e) Slowly push the vehicle straight ahead to cause the
front wheels to rotate 180° using the front tire valve
as a reference point.
HINT:
Do not allow the wheels to rotate more than 180°. If
the wheels rotate more than 180°, perform the
procedure from *1 again.

toe-in deviates toward the outside.
(2) Shorten the longer rack end if the measured
toe-in deviates toward the inside.
(e) Turn the right and left rack ends by equal amounts
to adjust the toe-in.

Try to adjust the toe-in to the center of the specified
range.
(f) Make sure that the lengths of the right and left rack
ends are the same.
(g) Tighten the tie rod end lock nuts.
Torque: 74 N*m (755 kgf*cm, 55 ft.*lbf)
NOTICE:
Temporarily tighten the lock nut while holding
the hexagonal part of the steering rack end so
