5. Align the notch on the inside of the seal with
the notch on the new headlight (Figure 40).
Slide the seal onto the headlight until the seal
is firmly in place.
6. Attach the headlight to the wire harness using
the previously removed screws.
7. Align the notch on the outside of the seal with
the notch in the hood. Push the headlight and
seal into the hood until it is firmly in place.
Note: Applying soapy water to the outside
of the seal may aid in sliding the seal into the
hood.

Maintenance

Inspecting the Tires

Check the tire condition at least every 100 hours
of operation. Operating accidents, such as hitting
curbs, can damage a tire or rim and also disrupt
wheel alignment, so inspect tire condition after an
accident.
Check the wheels to ensure that they are mounted
securely. Torque the center bolts on the front
wheels to 135-165 ft-lb (183-224 N⋅m) and the
front and rear lug nuts to 45-65 ft-lb (61-88 NVm).

Adjusting the Front

Suspension

The ride height of each side of the vehicle can
be adjusted separately. The ride height should be
8-3/4 to 9-1/2 inches (22.2 to 24 cm) with the
following parameters:
• The tire pressure should be at 12 psi (83 kPa).
• The vehicle should be driven back and forth a
few times to relax the A-arms.
• Measure the ride height 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.
• Measure the ride height on a flat surface, from
the bottom of the front tongue to the ground.
1. Jack the front end of the vehicle off of
the ground; refer to Jacking the Vehicle in
Premaintenance Procedures, page 30.
2. Remove the travel limiting bolt (Figure 41).
3. Loosen the centering bolts in the front A-arm
(Figure 41).
4. Remove the ride height adjustment bolt
(Figure 41).

5. Rotate the front A-arm to the desired position
(refer to the note below) and replace the ride
height adjustment bolt (Figure 41).
Note: The A-arms are made with rubber
and have different spring rates. Because of
the different spring rates, the A-arms come
adjusted from the factory based on that spring
rate. Generally the adjustment bolts will be
installed in hole number 2, 3, or 4 (Figure 42)
and it may be different from the left side (driver
side) to the right side (passenger side). If the
A-arms look like they are sagging, then they
should be adjusted to the next higher number
(Figure 42). Each hole equals about 3/4 inch
(19 mm) of adjustment at the wheel. You will
also need to do this if you are adding heavy
attachments or carrying heavy loads often.
