1. Left-hand A-arm
6. Torque the ride height adjustment bolt to
135-165 ft-lb (183-224 N-m).
7. Replace the travel limiting bolt (Figure 42).
Note: The vehicle may need to be lowered to the
ground on that side to install the bolt.
8. Tighten and torque the centering bolts to
240-290 ft-lb (325-393 N-m).
9. Check the ride height at the front tongue per the
dimensions and parameters given at the beginning of
this procedure.

Adjusting Front Wheel Toe-In

Check the front wheel toe-in after every 100 operating
hours, or annually, whichever occurs first.
The toe-in should be 1/8-5/8 inch (3-16 mm) with the
following parameters:
• The tire pressure should be at 12 psi (83 kPa).
• The ride height should be correct before setting the
toe-in; refer to Adjusting the Front Suspension.
• The vehicle should be driven back and forth a few
times to relax the A-arms.
• Measure the toe-in with the wheels facing straight
ahead and a 175-225 lb (79-102 kg) operator in the
driver's seat.
Note: The driver should drive up to the
measurement area and stay seated in the vehicle
while the measurement is being taken.
If the vehicle will be run with medium to heavy loads
most of the time, set the toe-in on the high side of
the recommended amount. If it is going to be run
with a light load most of the time, set the toe-in on
the low side of the recommended amount.
1. Ensure that the front suspension is adjusted
properly; refer to Adjusting the Front Suspension.
Adjust if necessary.
2. Measure the distance between both of the front tires
at the axle height at both the front and rear of the
front tires (Figure 44). A fixture or alignment gauge
is needed for the rear measurement of the front tires
at axle height. Use the same fixture or alignment
gauge to accurately measure the front of the front
tires at axle height (Figure 44).

2. Tire center line-front
3. Axle center line
3. If the measurement does not fall within the specified
range (refer to the dimensions and parameters at the
beginning of this procedure), loosen the jam nuts at
both ends of the tie rods (Figure 45).

4. Rotate both tie rods to move the front of the tire
inward or outward.
5. Tighten the tie rod jam nuts when the adjustment is
correct.
6. Ensure that there is full travel of the steering wheel
in both directions.
