PRELIMINARY OPERATIONS TO BE OBSERVED BEFORE
CHECKING THE STEERING ANGLES
1. Area (checking surface) – it must be a s horizontal as possible.
2. Wheels, tires – check (from e quipping point of vi ew) to have same type of wheels and
tires on bot h axles (dimensions, inflating pressure, wear de gree). A pronounced wear i s not
allowing the correct horizontal positioning.
3. Suspension – check the shock absorbers, springs condition and height symmetry under
carriage body.
4. Joints – check the e lastic joints condition, steering and suspension ball joints clearance,
bearings clearances of the front and rear axles 5. Radial and axial run out of the wheels – must not be over 1 mm. This will be compensated
with the reading instruments. 6. Manufacturer’s method – each vehicle manufacturer is providing the checking conditions,
axles weights repartition, and presentation of under carriage body heights, not loaded.
