IN CASE OF EMERGENCY
NOTE:
If the bottle jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to
use the jack driver in order to lower the jack.
7. By rotating the lug wrench clockwise, raise
the vehicle until the wheel just clears the
surface.
8. Remove the lug nuts and pull the wheel off.
On single rear-wheel (SRW) trucks, install
the spare wheel and lug nuts with the cone
shaped end of the wheel nuts toward the
wheel. On 3500 dual rear-wheel models
(DRW) trucks, if the outer tire is being
replaced then leave the inner wheel on the
vehicle. If the inner wheel is being replaced
remove the outer wheel and replace the
inner wheel. The wheel nuts are a two-piece
assembly with a flat face. Lightly tighten the
lug nuts. To avoid the risk of forcing the
vehicle off the jack, do not fully tighten the
lug nuts until the vehicle has been lowered.

9. Finish tightening the lug nuts. Push down on
the lug wrench while at the end of the
handle for increased leverage. Tighten the
lug nuts in a star pattern until each nut has
been tightened twice. For the correct lug nut
torque refer to “Torque Specifications” in
“Technical Specifications”. If in doubt about
the correct tightness, have them checked
with a torque wrench by an authorized
dealer or service station.
CAUTION!
Before raising the wheel off the ground, make
sure that the jack will not damage
surrounding truck parts and adjust the jack
position as required.
WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off
the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
