WHAT TO DO IN EMERGENCIES
When changing a rear wheel,
assemble the jack drive tube to the
jack and connect the drive tube to
the extension tube. Securely place
the jack under the sway bar bracket
(unless both tires are flat on one
side, then place jack under shock
bracket) facing forward in vehicle.
Connect the jack tube extension
and lug wrench.
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 drive
tube in order to lower the jack.
4. By rotating the wheel wrench
clockwise, raise the vehicle until the
wheel just clears the surface.
5. Remove the wheel nuts and pull the wheel off. Install the spare wheel and
wheel 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 wheel wrench, finish tightening the nuts using a crisscross pattern.
The correct nut tightness is 135 ft lbs (183 N·m) torque for single rear wheel
(SRW) models and 145 ft lbs (197 N·m) for dual rear wheel models. If in doubt
about the correct tightness, have them checked with a torque wrench by your
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.
