CambeR
Camber refers to the angle formed between the
wheel and the vertical. If the wheel tilts out
wards, the camber angle is said to be positive;
if
it
tilts
inwards, the angle is said to be negative.
The camber on the Saab
900
is positive.

2 Using the tracking gauge, measure dimen
sion Abetween the rims, at axle height.
Mark the measuring points with chalk. Roll
the car forward until the chall, marks are at
axel height again and then measure dimen
sion
In
this method, the tracking gauge remains
in the same pos it ion on the floor for both
measurements, thereby preventing any un
evenness in the surface of the floor from in
fluencing the measurements.
3 If adjustment is necessary, dothis byadjust
ing the length of the track rod. Slacken the
locknut at the track-rod
end
and the clip sec
uringthe gaiter on the steering rack.
4 Gripping the track rod with a suitable tool,
turn it clockwise or ant ic lockwise the
number
of
turns shown in
the
table on page
6 1 2 until the correct toe-in is obtained.
Make sure that the gaiter does not turn with
the track rod.

Adjusting
using
a
backing g ug
1 With the car on a perfectly level surface, roll
i t s traight ahead and allow it to come to a
stop by itself.
I f there is reason to belief that the front-wheel
alignment is incorrect e.g. because of abnormal
tyre wear, impaired steering or roadholding prop
erties, etc.) the following procedure should be
followed:
1 Check the tyre pressures.
2 Check the front-wheel bearings, wishbone
mountings and ball joints, and the inner ball
joints and track-rod ends. Adjust or replace
any defective parts as necessary, to elimi
nateanysymptoms caused by such defects.
3 Inspect the dampers and replace any that
are defective, togetherwith any worn rubber
bushes.
4 I f the car has been involved in a collision,
has run of f the road or the like, repair any
damage before starting wheel-alignment
checks.
5 To prevent distorted readings being ob
tained, rock the car fi rmly a few times to
allow the suspension to settle before start
ing any checks.
For checking of wheel alignment and steering
angles, the carmust be unladen, with nobody in
side i t, but wi th a ful l tank of fuel and on a per
fectly level surface. Adjustment by means of
shims must only beattempted within reasonable
limits; shims must not be used to correct major
discrepancies.

Camber can be adjusted by fitting suitable shims
under both bearing brackets for the top
wishbone.
When increasing or decreas ing the camber
angle, always fit ident ical shims under both
bearing brackets. Reducing the shim thickness
will increase the positive camber and increasing
the shim thickness will reduce the positive
camber. After measuringthe camber, referto the
table
on
page 601-6.
Shims are available
in
thicknesses
0.5
1. 0 and
2.0
mm, See the Technical Data section forthe
camber specification.
, -.
N.B.
The wishbone bearing nearerthe back of the car
is availab le in a thinner var iant which allows a
wider adjustment range.
See
the Parts
Catalogue.

The castor can be adjusted
byfitting
shims under
the bearing brackets for the top wishbone.
Moving shims from the forward bearing bracket
and fitting them under the rear bracket on the
wishbone will increase the castor and vice versa,
When a shim
of
a given thickness is removed
from under one bearing bracket, a shim
of
the
same thickness must be fitted under
the
otherto
avoid the camber being altered. After measuring
the castor, refer
to
the table on page 601-6.
Shims are available in thicknesses 0.5 1. 0 and
2 0 mm. Refer to the Technical Data section
fo r
the specified castor.

Altering of the camber wil l also alter the swivel
pin inclination by the same amount. Because the
ba sic swivel-pin inclination is determined by the
design of the steering swivel member, it cannot
be adjusted.
If
the swivel-pin inc lination is wrong after the
camber has been
set
correctly, the fault mustlie
with the steer ing swivel member, which must
therefore be replaced.

Before the steering angles
of
the wheels can
be
adjusted, the toe-in setting must be correctly ad
justed.
The
wheel angles are measured using
two turntables,
each
one centred underneath the
respective wheel.
Make surethe turntables are setto zero then turn
the outside wheel through 20
If
the steering
angle is correct, the angle
of
the inner wheel will
be
20.75 0.5 If the turning angle is incor
rect, then one
or
both track arms is distorted,
and must
be
replaced bending
of
track arms is
not permissible . As from M8i the track arms
are
an
integral part of
the
steering swivel
member, which means
if
atrack arm isdistorted,
the entire steering swivel member must be
re-
placed.
