•For 4x2 and 4x4 trucks, when changing a rear wheel, assemble the jack drive tube
to the jack and connect the drive tube to the extension tube. Place the jack under
the axle between the spring and the shock absorber with the drive tubes extending
to the rear.
• 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.
• Lower the jack to its fully closed position. 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. Stow the replaced tire, jack, and tools as previously
described.
• Adjust the tire pressure when possible.
NOTE:
Do not oil wheel studs. For chrome wheels, do not substitute with chrome plated
wheel nuts.
