To lower the spare tire from the vehicle:
2. Put the flat chisel end of the wheel wrench on an
angle through the hole between the body and the
bumper. Be sure the flat end connects into the
hoist shaft.
1. Attach the wheel
wrench and ratchet,
with the DOWN side
facing you. The wheel
wrench has a socket
end and a flat chisel
end. Note that there is
an UP side and a
DOWN side on the
ratchet.
3. Turn the ratchet counterclockwise to lower the
spare tire to the ground. 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 5-90.
