When changing a rear wheel, assemble the jack drive tube to the jack and
connect the drive tube to the extension tube. Securely place the jack under the
sway bar bracket (unless both tires are flat on one side, then place jack under
shock bracket) facing forward in vehicle. Connect the jack tube extension and lug
wrench.
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 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.
4. By rotating the wheel wrench clock-
wise, raise the vehicle until the wheel
just clears the surface.
5. Remove the lug nuts and pull the
wheel off. Install the spare wheel and
lug nuts with the cone shaped end of
the lug nuts toward the wheel on single rear wheel (SRW) models. On dual rear
wheel models (DRW) the lug nuts are a two-piece assembly with a flat face
(flanged). Lightly tighten the nuts. To avoid risk of forcing the vehicle off the jack,
do not fully tighten the nuts until the vehicle has been lowered.
6. Using the wheel wrench, finish tightening the nuts using a crisscross pattern. Use
the following chart for the correct tightness of the lug nuts:
Lug Nut/Bolt Torque Lug Nut/Bolt Type **Lug Nut/Bolt
Size
Lug Nut/Bolt
Socket Size
120-150 Ft-Lbs
(160-200 N·m)
Cone
M14 x 1.50 22 mm
130-160 Ft-Lbs
(190-220 N·m)
Flanged
If in doubt about the correct tightness, have them checked with a torque wrench
by your authorized dealer or at a service station.
7. Install wheel center cap (if equipped) and remove wheel blocks. Do not install
chrome or aluminum wheel center caps on the spare wheel. This may result in cap
damage.
8. Lower the jack to its fully closed position. If the 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. Stow the replaced tire, jack, and tools as previously described.
