CHECKING OF THE FRONT AXLE ADJUSTMENT
Case 1:
The symmetry dimension “X” is correct-the value “A” is equaled distributed.
Case 2:
The symmetry dimension “X” is incorrect-read the value “A” on each side, adds it, and
calculate the average value, establishing the value for each side.
Example:
Right side value : A = 16;
Left side value : A = 10;
16 + 10 = 26;
26 : 2 = 13;
Operating the steering rods tie bar, restore the same value for both sides A = 13.
In this position, lock the rotating plates at zero point.
Check in the following sequence:
- camber angle;
- caster angle;
- parallelism;
- ball joint angle.
PARALLELISM ADJUSTMENT
Loosen the lock nut (1) maintaining the tie
rod of steering connecting rod (2) in a fixed
position.
Act upon the tie rod of steering connecting
rod taking into account its rotation sense of
in order to obtain the convergence or
divergence and also the fact that one of its
complete rotation leads to an axial
displacement of 1,5 mm.
OBSERVATION
The opening between the wheel’s front
and rear is measured on a F=340 mm.
After obtaining the correct parallelism,
tighten the lock nut at the required moment
of 5 daNm.

GENERAL

Three situations may appear:
1.
CORRECT
INCORRECT
Perform the same rotation number of the tie rod
connecting rod on left side and on the right side until
obtaining the same value ”A”.
2
. INCORRECT
CORRECT
Adjust the parallelism at the same value for left and
right
side ensuring the same value “A” on both sides.
3
. INCORRECT
INCORRECT
Perform first the repartition in order to balance the value
“A” on each side, than adjust the parallelism (see Case 2}.

DIAGNOSIS
THE DEVIATION TO THE LEFT OR TO RIGHT AT STABLE SPEED
Perform the preliminary checking:

- pressure
- bushings
- dimensions
- types
