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).

parameters at the beginning of this procedure),
loosen the jam nuts at both ends of the tie
rods (Figure 45).
