Removing a wheel
\1Unscrew the wheel bolts or wheel nuts. \1For wheels with wheel nuts remove the
wheel nut cover.
\1Remove the wheel.Mounting the new wheel\1Clean the wheel and wheel hub contact
surfaces.
\1Push the wheel onto the wheel hub and
press it on.
!
CAUTION
Do not apply the jack to the leaf spring
or the differential housing.
!
CAUTION
Do not place the wheel bolts or the
wheel nuts in sand or dirt. The bolt and
wheel hub threads could otherwise be
damaged.
Warning
G
Replace the wheel bolts and wheel nuts if
they are damaged or have become rusty.
Never oil or grease wheel bolts or wheel
nuts.
If a wheel hub thread is damaged, you must
not drive the vehicle.
Consult an authorized Sprinter Dealer which
has the necessary specialist knowledge and
tools to carry out the work required.
The manufacturer recommends that you use
an authorized Sprinter Dealer for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at an authorized Sprinter Dealer.
For safety reasons, the manufacturer rec-
ommends that you only use wheel bolts and
wheel nuts which have been approved for
Sprinter vehicles. Other wheel bolts or
wheel nuts could work loose.
!
CAUTION
If your vehicle is equipped with the tire
pressure monitor, each wheel has an
electronic component.
Tire mounting tools should not be ap-
plied in the area of the valve, as this
could damage the electronic compo-
nents.
Have the tires changed only at an
authorized Sprinter Dealer.
Warning
G
Do not tighten the wheel bolts and wheel
nuts completely while the vehicle is still
jacked up. The vehicle could tip.

Wheels with centering by wheel bolts:
\1Screw in the wheel bolts and tighten
them finger-tight.

2Wheel bolt for steel wheelor wheels with wheel nuts:
For wheels with wheel nuts:
\1Center the wheel nut cover over the
wheel and push it onto the wheel.
\1Screw on the wheel nuts and tighten
them finger tight.
Lowering the vehicle
\1Slowly open the jack’s pressure release
screw one turn using the pump lever
(\2page 322) and lower the vehicle
slowly.
\1Put the jack to one side.Tightening torque pattern
1 – 6 Wheel bolts
\1Tighten all the wheel bolts and wheel
nuts evenly in the sequence indicated.
As an extension for the wheel wrench,
use the shaft from the jack’s 3-part
pump lever that has the largest diame-
ter.
iOn vehicles with light-alloy wheels, you
will find short wheel bolts suitable for
the steel spare wheel in the vehicle tool
kit.N40.10-2175-31
iScrew on the three wheel nuts that
hold the wheel nut cover first.

CAUTION
The tightening torque is:
\4for wheel bolts 177 lb-ft (240 Nm)
(steel wheel)/133 lb-ft (180 Nm)
(light-alloy wheel).
\4for wheel nuts 133 lb-ft (180 Nm)

\1For wheels with wheel bolts attach the
wheel cover.
Vehicles with wheel caps:
Make sure that the opening in the
wheel cap is positioned over the tire
vent.
Vehicles with center caps:
Make sure that the retaining lugs of the
hub cap are positioned over the bolts.
\1Compress the piston of the hydraulic
jack and close the pressure release
screw.
\1Store the jack and the remaining vehi-
cle tools.
\1Place the defective wheel in the spare
wheel bracket after changing the wheel
(\2page 301).
\1Check the tire pressure (\2page 210).
\1Retighten the wheel bolts and wheel
nuts to the specified tightening torque
once the vehicle has been driven for 30
miles (50 km).
iGive the middle of the center cap a
knock to engage it on the wheel.
Warning
G
For safety reasons, you must observe the
following after changing a wheel:
\4Have the tightening torque checked:
\4for wheel bolts 177 lb-ft (240 Nm)
(steel wheel)/133 lb-ft (180 Nm)
(light-alloy wheel) or
\4for wheel nuts
133 lb-ft (180 Nm).
The wheels could otherwise come loose.
\4Check the tire pressure and correct it if
necessary
\4Have the wheel bolts or wheel nuts re-
tightened after 30 miles (50 km) to a
torque of:
\4177 lb-ft (240 Nm) (steel wheel)/
133 lb-ft (180 Nm) (light-alloy
wheel) for wheel bolts or
\4133 lb-ft (180 Nm) for wheel nuts.
\4Have the direction of tire rotation cor-
rected, if reversed, as soon as possible
at an authorized Sprinter Dealer. The ve-
hicle handling characteristics could oth-
erwise be affected.Warning
G
Loose wheel nuts or bolts could cause the
vehicle to lose a wheel while it is in motion.
This would jeopardize the operating and
road safety of the vehicle. You could lose
control of the vehicle as a result, cause an
accident and injure yourself or others.
If new or repainted wheels are mounted, the
wheel bolts or wheel nuts must be retight-
ened again after approximately 600 to 3000
miles (about 1000 to 5000 km).

electric air pump and the tire sealant bottle.Warning
G
Tire sealant must not come into contact with
your skin, eyes or clothing.
\4If tire sealant comes into contact with
your eyes or skin, immediately rinse
thoroughly with clean water.
\4Immediately change out of clothing that
has been in contact with tire sealant.
\4If an allergic reaction occurs, consult a
doctor immediately.
Keep tire sealant away from children.
\4If tire sealant is swallowed, immediately
rinse your mouth out thoroughly and
drink plenty of water.
\4Do not induce vomiting. Consult a doc-
tor immediately.
Do not inhale tire sealant fumes.
iThe tire sealant is water soluble. If tire
sealant escapes, you can wash it away
with water.
