To lower the spare tire from the vehicle, do the
following:
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 373.
