288 IN CASE OF EMERGENCY
Rear Jacking Location
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.
NOTE:
If the 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.
4. By rotating the lug wrench clockwise, raise
the vehicle until the wheel just clears the
surface.
5. Remove the lug nuts and pull the wheel off.
Install the spare wheel and lug nuts with the
cone shaped end of the nuts toward the
wheel on Single Rear-Wheel (SRW) models.
On Dual Rear-Wheel models (DRW) the lug
nuts are a two-piece assembly with a flat
face. Lightly tighten the nuts. To avoid risk
of forcing the vehicle off the jack, do not
fully tighten the nuts until the vehicle has
been lowered.
6. Using the lug wrench, finish tightening the
nuts using a crisscross pattern. For the
proper lug nut torque specifications refer to
“Wheel And Tire Torque Specifications” in
“Technical Specifications.” If in doubt about
the correct tightness, have them checked
with a torque wrench by an authorized
dealer or at a service station.
7. Install wheel center cap (if equipped) and
remove wheel blocks. Do not install chrome
or aluminum wheel center caps on the
spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. If
the 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. Stow the replaced tire, jack, and tools
as previously described.
9. Adjust the tire pressure when possible.
10. After 25 miles (40 km), check the lug nut
torque with a torque wrench to ensure that
all lug nuts are properly seated against the
wheel.
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.
WARNING!
A loose tire or jack thrown forward in a
collision or hard stop, could endanger the
occupants of the vehicle. Always stow the jack
parts and the spare tire in the places
provided.
