c. Check toe-in.
When setting toe-in adjustment, the front
suspension must be neutralized; that is all
component parts must be in the same relative
position when making the adjustment as they
will be in operation. To neutralize the
suspension, the vehicle must be rolled forward
12-15 feet (3.65-4.57 m). By rolling the vehicle
forward, all tolerances in the front suspension
are taken up and the suspension is then in
normal operating position. Neutralizing the
especially if the vehicle has been jacked up in
order to scribe the tires; otherwise, the front
wheels will not return to the normal operating
position due to the tires gripping the floor
surface when the vehicle is lowered.
(1) Actual toe-in measurements should be taken at
hub height between the two points on the center
of the tread at the rear of the tires.
(2) Mark the point and roll the truck ahead so that the
points are in the front at hub height and measure
the distance between the same two points on the
The difference in the two measurements is the
actual toe-in or toe-out.
(3) To adjust the toe-in, turn the steering wheel so
that the gear is in the mid-position.
(4) Loosen the clamping bolts on the tie rod.
(5) Turn the tie rod in the direction necessary to bring
toe-in within the specified limits.
(6) Tighten the clamping bolts on the tie rod.
