2. The front tires must be properly
inflated. If necessary, move a
rear tire to the front to replace a
flat or damaged tire.
3. Place the tow chain hooks (2)
into one of the torque box
openings (1) behind the front
wheels.
4. Place a 1.2 m (4 ft) X 102 mm
(4 in) X 102 mm (4 in) wood
beam (4) under the front cradle
crossmember (3), and on top of
both tow chains (5) to ensure the
tow chains do not come into
contact with the front fascia (1).
Try to minimize the contact of
the chains with the flexible
air dam (2).
5. Ramps (2) are required for the
front fascia (3) to clear the
flatbed (1). The ramp height
should be approximately 102 mm
(4 in). Lower the flatbed onto the
set of ramps.
Notice: If ramps are not used, the
front fascia will come into contact
with the flatbed and may cause
damage. Always use ramps.
6. After the front tires are on the
flatbed adjust the flatbed upward
to provide additional clearance
between the air dam, fascia, and
flatbed.
