Front wheel alignment angle -
checking and adjustment
The check and adjustment of the front wheel alignment angle
is carried out on special test-benches according to the instruc-
tions.
ATTENTION. It is necessary to check the wheel align-
ment angle after replacement or repair of suspension com-
ponents, that could have caused the misalignment of wheel
angle.
The check and adjustment of wheel angles is carried out on
a vehicle under static load of 3140 N (320 kgf) (four men and 40
kg in boot).
Follow the parameters specified in tab. 4-1 to check and
adjust the wheel alignment angles.
