WHEEL ALIUNIVItNT
cENERAL
It is of the utmost importance that the front wh l
correctly aligned, since incorrect steering geom ee 5 be
cause: etry can
1, Driving fatigue, due to impaired roadability
2. Increased tire and repair costs due to abnorm |
of tires and steering mechanism. a Wear
If there is reason to suspect incorrect front wheel ali n-
ment as the result of an accident or of driving into tlfe
ditch, for example, or if road behaviour is noticeably im—
paired, the car should immediately be taken to an autho-
rized service shop for inspection and adjustment. Efen if
there is no direct reason to suspect faulty wheel alignment
the car should nevertheless be checked at regular intervals
and adjusted whenever necessary.
The angles and dimensions directly affecting the front-
wheel alignment, all of which are closely interrelated, are
the following:
King-pin inclination
Caster
Camber
Toe-in and
Wheel turning angles
1. Check that the tire pressure is correct and that the
front tires are not too unevenly worn.
2. Check the front wheel bearings, control arm bearings,
ball joints and tie-rod ends, adjusting or replacing as
necessary in order to eliminate errors that can be
mused by worn parts.

Check the steering gear and adjust any faults - see
section 642.
4- Check the function of the shock absorbers and renew
any defective shock absorbers and rubber bushings.
5. If the car has been involved in an accident, driven into
the ditch, etc, any damage incurred must be repaired
before the alignment check. Distorted steering arms
must be rejected and new ones fitted, as restraightening
IS not permitted.
6- Immediately prior to the check, drive the car with nor-
rnal suspension movement but without hard cornering
In order to avoid deceptive misalignment. For the same
reason, the car should also be rocked a few times.
The car must be unladen during the alignment check and
standing on a flat, horizontal floor, as otherwise measure-
ments will not be reliable.
All adjustment with shims must be kept within reasonable
limits. Deformation resulting from crash damage, etc,
must be corrected by thorough realignment of the body.
Distorted control arms must be rejected and new ones
fitted.
For checking wheel alignment there are various standard
tools, which are fitted either to the rim or directly on the
stub axle. Tool handling is described in the instructions
for each individual tool.
NOTE
When using axle-fitted tools on cars with a front
wheel drive, the wheels must stand on turn-tables
or similar devices and should be locked with the
brakes during the course of the check.
