FRONT AXLE CHECKING -ADJUSTMENT
Case 1. The symmetry dimension “X” is correct:
- the value “A” is equal distributed.
Case 2. The symmetry dimension “X” is incorrect:
- read the value “A” on each side, mark it, calculate an average value, establishing the
value for each side.
E
XAMPLE
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 side A = 13.
In this position, lock the rotating plates to zero point.
Check in order: 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 rod of steering connecting
rod taking into account the rotation sense of
latter in order to obtain the convergence or
divergence and also the fact that one of its
complete rotation leads to an axial displace-
ment of 1,5 mm.
After obtaining the correct parallelism,
tighten the lock nut at a moment of 5 daNm.

INCORRECT
It is performed the same number of connecting rod rotation
on left side and right side until obtain the same value ”A”.
Adjust the parallelism at the same value for left and right side
ensuring in the same time, the same value “A” on both sides.
First operate on repartition in order to balance the value
“A” on each side, than adjust the parallelism (see Case 2}.
