Clean any rust or dirt from the contact sur-
faces between the wheel and brake disc.
4 Clean any rust or dirt from the contact
surfaces between the wheel and brake
disc. Do not wipe away the grease in the
wheel hub.
5 Add a thin layer of grease on the bolts
before fitting, see page 261. Fit the
wheel and screw in the bolts in the
sequence shown on page 262 (opposite
pairs).
Tighten the bolts enough for the bolts
and wheel to be seated correctly.
6 Lower the car and tighten the wheel
bolts to torque in sequence as shown on
page 262.
Tightening torque
Light-alloy wheels: 80 ft.lb. (110 Nm).
Steel wheels: 80 ft.lb. (110 Nm).
Do not wipe away the grease in the wheel
hub.
Lubricate the heads of the wheel studs
with a small amount of Vaseline or simi-
lar and refit the plastic covers on the
wheel studs. The Vaseline makes it
easier to remove them later on.
NOTICE
• Do not overtighten the bolts using a
impact wrench: not only can this
damage the wheels but it can also
make it impossible to undo the bolts
using the wheel wrench in the car's
toolkit.
• When refitting a wheel cover, make
sure that the valve protrudes through
the marked recess in the wheel cover.
Car care
Grease the surfaces indicated with a thin
layer of grease
7 Retouching the wheel bolts after twenty
or so miles.
Tightening torque
Light-alloy wheels: 80 ft.lb. (110 Nm).
Steel wheels: 80 ft.lb. (110 Nm).
We advise against using wheels with large
ventilation slots in winter, as the brake com-
ponents are then more exposed to slush,
road salt and grit.
If you fit wheels of a different dimension, the
speedometer can be reprogrammed to
ensure it is as accurate as possible. We rec-
ommend that you contact a Saab dealer.
