5. After making sure that no one is in the vehicle, as the jack
touches the vehicle and begins
to lift, doublecheck that it is
properly positioned.

groove on the top of the jack fits with
the rear axle housing.

6. After making sure that no one is in the vehicle, raise it high
enough so that the temporary
spare tire can be installed.
Remember you will need more ground
clearance when putting on the tempo-
rary spare tire than when removing
the flat tire.
—Raising your vehicle

512
2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
To raise the vehicle, insert the jack
handle end with the extension into the
jack (it is a loose fit) and turn it clock-
wise with the handle. As the jack
touches the vehicle and begins to lift,
double −check that it is properly posi-
tioned.
CAUTION
Never get under the vehicle when
the vehicle is supported by the
jack alone.
XS40018
7. Remove the wheel nuts and change tires.
Lift the flat tire straight off and put it
aside.
Roll the spare wheel into position and
align the holes in the wheel with the
bolts. Then lift up the wheel and get
at least the top bolt started through
its hole. Wiggle the tire and press it
back over the other bolts.
XS40019
Before putting on wheels, remove any
corrosion on the mounting surfaces
with a wire brush or such. Installation
of wheels without good metal− to−met-
al contact at the mounting surface can
cause wheel nuts to loosen and
eventually cause a wheel to come off
while driving.

8. Reinstall all the wheel nuts fin-
ger tight.
Reinstall the wheel nuts (tapered end
inward) and tighten them as much as
you can by hand. Press back on the
tire back and see if you can tighten
them more.
CAUTION
Never use oil or grease on the
bolts or nuts. Doing so may lead
to overtightening the nuts and
damaging the bolts. The nuts
may loosen and the wheels may
fall off, which could cause a seri-
ous accident. If there is oil or
grease on any bolt or nut, clean
it.
XS40021
9. Lower the vehicle completely and tighten the wheel nuts.
Turn the jack handle end with the ex-
tension counterclockwise with handle
to lower the vehicle, making sure the
handle remains firmly fitted onto the
jack handle extension.
Use only the wheel nut wrench and
turn it clockwise to tighten the nuts.
Do not use other tools or any addition-
al leverage other than your hands,
such as a hammer, pipe or your foot.
Make sure the wrench is securely en-
gaged over the nut.

514
2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
Tighten each nut a little at a time in
the order shown. Repeat the process
until all the nuts are tight.
CAUTION
When lowering the vehicle,
make sure all portions of your
body and all other persons
around will not be injured as
the vehicle is lowered to the
ground.
Have the wheel nuts tightened
with a torque wrench to the fol-
lowing torques, as soon as
possible after changing
wheels. Retighten the wheel
nuts within 160 km (100 miles)
of driving. Otherwise, the nuts
may loosen and the wheels
may fall off, which could cause
a serious accident.
Due to the higher torque
specification for these wheel
nuts, if in doubt about the
correct tightness, have them
checked by your Toyota deal-
er or at a service station.

209 N· m (21. 3 kgf · m , 154 ft · lbf )
Flat washer type
(Aluminum wheels)—
131 N·m (13.4 kgf·m, 97 ft·lbf)
∗
∗
: When temporarily used on spare tire/wheel, apply 209 N·m (21.3
kgf·m, 154 ft·lbf) 10.Check the air pressure of the re-
placed tire.
Adjust the air pressu re to the specifi-
cation designated on page 594 in
Section 8. If the pressure is lower,
drive slowly to the nearest service
station and fill to the correct pressure.
Do not forget to reinstall the tire infla-
tion valve cap as dirt and moisture
could get into th e valve core and
possibly cause air leakage. If the cap
is missing, have a new one put on as
soon as possible.
11. Restow all the tools, jack and flat tire securely.
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 515 with a
torque wrench. Have a technician re-
pair the flat tire and replace the tem-
porary spare tire with it. Initial adjustment of the tire
pressure warning system is
necessary after your have replaced
your tires or wheels. See “Tire
pressure warning system” on page
254 in Section 17.CAUTION
Before driving, make sure all the
tools, jack and flat tire are se-
curely in place in their storage
location to reduce the possibility
of personal injury during a colli-
sion or sudden braking.

Aluminum wheels:
Before stowing the flat tire, remove
the center wheel ornament by pushing
from the reverse side.
Be careful not to lose the wheel orna-
ment.
If your vehicle becomes stuck in snow,
mud, sand, etc., then you may attempt
to rock the vehicle free by moving it
forward and backward.
Your vehicle is equipped with the
“AUTO LSD” system, you can use it in
this situation. (For details, see “AUTO
LSD system” on page 246 in Section
17.)
CAUTION
Do not attempt to rock the vehicle
free by moving it forward and back-
ward if people or objects are any-
where near the vehicle. During the
rocking operation the vehicle may
suddenly move forward or backward
as it becomes unstuck, causing injury
or damage to nearby people or ob-
jects.
NOTICE
If you rock your vehicle, observe the
following precautions to prevent dam-
age to the transmission and other
parts.
Do not depress the accelerator ped-
al while shifting the selector lever
or before the transmission is com-
pletely shifted to forward or reverse
gear.
 Do not race the engine and avoid
spinning the wheels.
 If your vehicle remains stuck after
rocking the vehicle several times,
consider other ways such as tow-
ing.

(a) Towing with wheel lift type truck— —From front
—From rear
(b) Using flat bed truck
Fourwheel drive modelsIf towing is necessary, we recommend
you have it done by your Toyota dealer
or a commercial tow truck service. In
consultation with them, have your ve-
hicle towed using either (a) or (b).
Only when you cannot receive a towing
service from a Toyota dealer or
commercial tow truck service, tow your
vehicle carefully in accordance with the
instructions given in “—Emergency
towing” on page 519 or 521 in this
Section.
Proper equipment will help ensure that
your vehicle is not damaged while being
towed. Commercial operators are generally
aware of the state/provincial and local
laws pertaining to towing.
Your vehicle can be damaged if it is
towed incorrectly. Although most operators
know the correct procedure, it is possible
to make a mistake. To avoid damage to
your vehicle, make sure the following pre-
cautions are observed. If necessary, show
this page to the tow truck driver.
TOWING PRECAUTIONS:
Use a safety chain system for all towing,
and abide by the state/provincial and local
laws. The wheels and axle on the ground
must be in good condition. If they are
damaged, use a towing dolly.
If your vehicle needs to be
towed—

NOTICE
Never tow a vehicle from the front
with the rear wheels on the ground,
as this may cause serious damage to
the transmission.

“ACC” position.
NOTICE
 When lifting wheels, take care to
ensure adequate ground clearance
for towing at the opposite end of
the raised vehicle. Otherwise, the
bumper and/or underbody of the
towed vehicle will be damaged dur-
ing towing.
 Do not tow with the key removed or
in the “LOCK” position, as the
steering lock mechanism is not
strong enough to hold the front
wheels straight while towing.
