• For rear wheels, 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.
• Turn the jack screw clockwise to
firmly engage the jack saddle with
the lift area.
• Raise the vehicle by turning the jack
screw clockwise. Raise the vehicle
only until the tire just clears the
surface and enough clearance is
obtained to install the spare tire.
• Remove the lug nuts and wheel.
• Position the spare wheel/tire on the vehicle and install the lug nuts with the
cone-shaped end toward the wheel. Lightly tighten the lug nuts clockwise. To
avoid the risk of forcing the vehicle off the jack, do not tighten the nuts fully
until the vehicle has been lowered.
• Lower the vehicle by turning the jack screw counterclockwise, and remove the
jack and wheel blocks.
NOTE: If the jack will not lower by turning the screw by hand, it may be necessary
to use the jack drive tube in order to lower the jack.
• Finish tightening the lug nuts using a crisscross pattern. Push down on the
wrench while tightening for increased leverage. The correct wheel nut
tightness is:
• 135 ft lbs (183 N·m) torque for single rear-wheel (SRW) models,
• 145 ft lbs (197 N·m) for dual rear-wheel (DRW) models.
• If in doubt about the correct tightness, have them checked with a torque
wrench by your authorized dealer or at a service station.
• Install the wheel center cap and remove the wheel blocks. Do not install
chrome or aluminum wheel center caps on the spare wheel. This may result in
cap damage.
• Secure the tire, jack, and tools in their proper locations.
• Position the wheel so that the valve stem is facing the ground. Slide the wheel
retainer through the center of the wheel and position it properly across the
wheel opening.
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.
