• Connect the jack tube extension and wheel wrench.
NOTE:
If the bottle 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.
• By rotating the wheel wrench clockwise, raise the vehicle until the wheel just
clears the surface.
• Remove the wheel nuts and pull the wheel off. On single rear-wheel (SRW) trucks,
install the spare wheel and wheel nuts with the cone shaped end of the wheel nuts
toward the wheel. On 3500 dual rear-wheel models (DRW) the wheel nuts are a
two-piece assembly with a flat face. Lightly tighten the wheel nuts. To avoid the
risk of forcing the vehicle off the jack, do not fully tighten the wheel nuts until the
vehicle has been lowered.
• Using the lug wrench, finish tightening the wheel nuts using a crisscross pattern.
The correct wheel nut tightness is 130 ft lbs (176 N·m) torque (1500 Series),
135 ft lbs (183 N·m) torque for 2500/3500 single-rear wheel (SRW) models, and
140 ft lbs (190 N·m) for 3500 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.
• 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.
