•
Remove the rubber flex extenders from the
side extenders. Failure to do so could re-
sult in the loss of the rubber flex extenders.
•
Hold down the cab with tension straps
looped over the cab shocks and under the
frame rails. Failure to do so could allow the
wind load to lift the cab unexpectedly, re-
sulting in damage to the air springs and
other components.
1. If the vehicle is equipped with side extenders,
and reverse towing at speeds above 45 mph (70
kph) is necessary, remove the rubber flex ex-
tenders from the side extenders.
2.
If the vehicle is equipped with cab air suspen-
sion, and reverse towing at speeds above 45
mph (70 kph) is necessary, hold down the cab as
follows:
2.1 Drain the air from the cab air springs.
2.2 Loop a 2-inch (5-cm) ratchet-style tension
strap (rated 2000 lb [900 kg] minimum
work load) over the top of the cab shock
and under the frame rail. See
Fig. 26.16 .
Tighten the strap for a snug fit. If the cab
is equipped with two or more shocks, re-
strain the aftmost shock on each side of
the vehicle.
3.
Place the front tires straight forward and secure
the steering wheel in this position.
4.
Disconnect the battery ground cables.
NOTICE
Failure to protect the frame rails from the chains
could cause damage, leading to eventual frame
failure.
5.
On dual drive axles, using protection to keep the
chains from damaging the vehicle frame, chain
the forward-rear drive axle to the frame.
NOTICE
Before towing, failure to remove an aerodynamic
bumper equipped with an air dam could result in
damage to the air dam, which will impact the ve-
hicle’s aerodynamic performance.
6. Remove the aerodynamic bumper if it is
equipped with an air dam.
7. Attach the towing device.
NOTE: Due to the many variables that exist in
towing, positioning the lifting and towing device
is the sole responsibility of the towing-vehicle
operator.
8. Lift the vehicle and secure the safety chains. If
extra clearance is needed, remove the bumper
extension if equipped.
9.
Connect the clearance lights, taillights, and sig-
nal lights. Also connect any special towing lights
required by local regulations.
