CAMBER INSPECTION

●

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

If outside the standard value, adjust with adjusting bolt in front lower
link.

CAUTION:

After adjusting camber, be sure to check toe-in.

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 vehicle before push-
ing it.

1.

Bounce rear of vehicle up and down to stabilize the posture.

3.

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

4.

Measure distance “A” (rear side).

5.

Push vehicle slowly ahead to rotate wheels 180 agrees (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.
6.
