• Make sure that no person is in front of the vehicle before pushing it.
1. Bounce the front of vehicle up and down to stabilize the vehicle height (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 front tires
at the same height as hub center as shown. These marks are
measuring points.
4. Measure the distance (A) on the rear side of the front tires as
shown.
5. Push the vehicle slowly ahead to rotate the wheels 180
°
degrees (1/2 a turn).
CAUTION:
If the wheels have rotated more than 180
° degrees (1/2
turn), start this procedure again from the beginning. Do not
push the vehicle backward.
6. Measure the distance (B) on the front side of the front tires at the
same marks as shown. Total toe-in is calculated as (A – B).
7. Adjust the toe-in by varying the length of the steering outer tie-
rods.
a. Loosen the outer tie-rod lock nuts.
b. Adjust the toe-in by screwing the outer tie-rods in or out.

and RH road wheels.
2. Start engine and run at idle, turn steering wheel all the way right
and left, measure the turning angle.
• Any turning angles are not adjustable. If any of steering angles
are out of the specification, check if the following parts are
worn or damaged.

• Check the ball joint for excessive play. Replace the upper or lower link assembly if any of the following
exists:
• Ball joint stud is worn.
• Ball joint is hard to swing.
• Ball joint play in axial directions or end play is excessive.
Swinging Force
NOTE:
Before checking the axial forces and end play, turn the lower ball joint at least 10 revolutions so that the ball
joint is properly broken in.
1. Measure the ball joint swinging force using a suitable tool.
• Measure at the cotter pin hole for upper ball joint as shown.
• Measure at the groove for lower ball joint as shown.
2. Verify the ball joint swinging force is within specification.
Turning Force
NOTE:
Before checking the axial forces and end play, turn the lower ball
joint at least 10 revolutions so that the ball joint is properly broken in.
