STRAIGHT-AHEAD CHECK
After all the necessary operations on the steering gear
are completed, check the exact straight-ahead position
of the steering in each case.
With the vehicle on the floor, place the steering wheel in
the straight-ahead position. Mark the centerline of both
tires on the floor. Turn the steering wheel all the way to
the right and mark the new centerline of both tires on the
floor.

STEERING WHEEL RESTORATION
1. Turn the steering wheel fast to the right and left and
turn it slowly as the same way.
2. Check if the steering wheel restoration for the wheel
turning to right and the one to the left are same.
3. Turn the steering wheel to 90 about 1–2 seconds
and loosen the steering wheel during the low speed
driving.
4. If the steering wheel restores above 70%, the steer-
ing wheel restoration is OK.
5. If the restoration is poor, check the tire pressure,
steering gear preload, and steering gear operation.
And repair the fault.
CHECK THE TURNING RESISTANCE
OF THE TIE ROD END OR TIE ROD
1. Turn the ball joint of the tie rod end or the tie rod about
10 times.
2. Use a spring balance to check the turning resistance
of each ball joint.
D105B302
Application Specified Value
Tie Rod End Ball Joint0.49 – 3.43 Nm
(4.5 – 30 lb-in.)

Tie Rod Ball Joint0.49 – 3.43 Nm
(4.5 – 30 lb-in.)
3. If the values exceed the specified values, replace the
tie rod end or the tie rod.
4. But, If the ball joint of the tie rod end or the tie rod falls
down of itself, replace it.
ADJUST THE FREE LOAD OF THE
STEERING GEAR
1. Place the steering wheel in the straight–ahead posi-
tion.
2. Raise and suitably support the vehicle.
3. Check the torque of the adjuster plug.
4 When the measured torque is below the specification
value or the measured torque is over the specification
value, adjust the tightening torque.

Place the rack gear in the straight–ahead position.

Tighten the adjust plug to 95 Nm (70 lb-ft).

Turn the steering wheel all the way to the right and
the left about 5 times repeatedly.

Place the rack gear in the straight–ahead position.

Loosen the adjust plug.

Tighten the adjust plug to 8 Nm (71 lb-in.).

Set the torque in the 0.8–1.3 Nm (8–12 lb-in.) by
loosening the adjust plug to 0 − 90.
