IN CASE OF EMERGENCY 339
5. Remove the lug nuts and pull the wheel off. On
Single Rear Wheel (SRW) trucks, install the
spare wheel and lug 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 replaced 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 lug nuts. To avoid the risk of
forcing the vehicle off the jack, do not fully
tighten the lug nuts until the vehicle has been
lowered.
