connects to the hoist shaft (B). The ribbed
square end of the extension is used to lower
the spare tire.
5. Turn the wheel wrench (E) counterclockwise
to lower the spare tire (H) to the ground.
Continue to turn the wheel wrench until the
spare tire can be pulled out from under
the vehicle.
If the spare tire does not lower to the ground,
the secondary latch is engaged causing
the tire not to lower. See Secondary Latch
System on page 537 for more information.

wrench hook that
allows you to
pull the hoist cable

retainer (G) at the
end of the cable
when the tire
has been lowered,
so it can be
pulled up through
the wheel opening.
