Inspecting the Tires
Chec k the tire condition at least ev er y 100 hours
of operation. Operating accidents , suc h as hitting
curbs , can damag e a tire or rim and also disr upt
wheel alignment, so inspect tire condition after an
accident.
Chec k the wheels to ensure that they are mounted
securely . T or que the lug n uts to 45-65 ft-lb
(61-88 N ⋅ m).
Adjusting the Front
Suspension
T he ride height of eac h side of the v ehicle can
be adjusted se parately . T he ride height should be
8-3/4 to 9-1/2 inc hes (22.2 to 24 cm) with the
follo wing parameters:
• T he tire pressure should be at 12 psi (83 kP a).
• T he v ehicle should be dri v en bac k and for th a
few times to relax the A-ar ms .
• Measure the ride height with the wheels facing
straight ahead and a 175-225 lb (79-102 kg)
operator in the dri v er’ s seat.
Note: T he dri v er should dri v e up to the
measurement area and sta y seated in the v ehicle
while the measurement is being tak en.
• Measure the ride height on a flat surface , from
the bottom of the front tongue to the g round.
1. J ac k the front end of the v ehicle off of
the g round; refer to J ac king the V ehicle in
Premaintenance Procedures , pag e 28 .
2. R emo v e the tra v el limiting bolt ( Figure 42 ).
3. Loosen the centering bolts in the front A-ar m
( Figure 42 ).
4. R emo v e the ride height adjustment bolt
( Figure 42 ).

5. R otate the front A-ar m to the desired position
(refer to the note belo w) and re place the ride
height adjustment bolt ( Figure 42 ).
Note: T he A-ar ms are made with r ubber
and ha v e different spring rates . Because of
the different spring rates , the A-ar ms come
adjusted from the factor y based on that spring
rate . Generally the adjustment bolts will be
installed in hole n umber 2, 3, or 4 ( Figure 43 )
and it ma y be different from the left side (dri v er
side) to the right side (passeng er side). If the
A-ar ms look lik e they are sag ging, then they
should be adjusted to the next higher n umber
( Figure 43 ). Eac h hole equals about 3/4 inc h
(19 mm) of adjustment at the wheel. Y ou will
also need to do this if y ou are adding hea vy
attac hments or car r ying hea vy loads often.
