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 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.

5. Remove the wheel nuts and pull the wheel off. Onsingle 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) trucks, if the outer tire is being re-
placed then leave the inner wheel on the vehicle. If the
inner wheel is being replaced remove the outer wheel
and replace the inner wheel. 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.
