1 steering wheel and front wheels must not be touched throughout the whole of
the testing operation.
2. Check readings Ll and L2 ( see chapter I ).
3. Adjust the length of the telescopic rods approximately according to the front track of the vehicle, both rods
being of the some length.
IMPORTANT : Place the rods on either side of front axle so that they are parallel to each other and perpendicular
to the longitudinal axis of the vehicle and the overall
distance between them is exactly 2.48 meters.
The rods need not necessarily be at equal distance from the axle but the spacing between them is essential.
4.
To make the test :
Pivot one of the two projectors towards the front rod hnd read off on the graduated rule thr value indicated by the
luminous mark. Then pivot projector towards the rear rod and move this laterally until the snne reading is obtained
as for the front rod.
Repeat this operation with the other projector, pivotting it successively towards the rear rod and then towards
the front
rod and each time note the readings indicated by the luminous mark.
The reading shown on the rem alignment rod should be 1 to 4 graduations greater than the reading shown on the
front alignment rod which corresponds to a
toe-in between 1 to 4 mm.
NOTE Never adjust the lens between the two front and rear readings.

be carried out in certain ccxses such as
-accidental impact, with repercussions on the steering system.
-work on the vehicle entoiling removal of steering crossmember.
