EnCoUnTERED VEHICLE
ALIGnMEnT FAULTs
Vehicle tends to wander to the left or the
right.
Cause: tyre side slip.
Invert the position of the wheels on the same
axle:
if the vehicle now tends to wander to the other
side, take one of the wheels whose position
you have already inverted and turn the tyre
on the rim;
if the wander direction does not change per-
form the same operation on the wheels of the
other axle;
if this double inversion procedure fails to solve
84
the problem, check that camber values on the
same axle are identical, make the same compari-
son for caster values.
Steering wheel not aligned with vehicle tra-
jectory.
Possible causes:
- mechanical backlash;
- ROC has been skipped or performed incor-
rectly;
- wheel alignment performed using two sensor
procedure;
- wheel alignment performed with the steering
wheel off centre;
- front wheels adjusted with respect to the axis
of symmetry.
Disparity between steering locks.
The steering box range must be centred by
counting the number of steering wheel revolu-
tions from full lock to full lock.
Position the steering wheel in the centre of its
range, clamp the steering wheel and perform
the normal procedure for adjustment of the front
half toe values.
Position the steering wheels correctly, disassem-
bling it from the steering column if needs be.
Steering wheel is excessively stiff with vehicle
stopped.
Possible causes:
- excessive caster;
- incorrect king-pin angle;
- excessive camber.
Steering wheel return is too forceful or insuf-
ficient when driving.
Incorrect caster value - adjust.
Tyre wear.
- Tyres with irregular wear on both sidewalls:
incorrect pressure - under-inflated.
- Tyre with irregular wear in the centre of the
tread: incorrect pressure - over-inflated.
- Tyre wear with stepped wear profile: shock
absorber not working properly.
- Tyres on the same axle with irregular wear on
a single sidewall: toe out of tolerance.
- Only one tyre on the same axle with an irregu-
larly worn sidewall: camber out of tolerance.
Vehicles with one register only.
Adjust the total toe to the value specified by
the manufacturer.
