The crossmember supporting the steering has slots at its fixing point on the front subframe.
Any vertical movement of this crossmember alters the steering geometry.
WARNING
This operation is only to
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.
- vehicle with poor
road stability ( p oar stright-line stability) 01 with excessive tyre weor.
CHECKING

Do not actuate steering wheel during check
( hydraulic locking of rock 1.
As a precaution. a steering wheel iocking
tool may also be
used. 2. Mark position of vehicle in relation to
ground :
Secure a weighted length of string to the front
bumper. and
mark the position of the weiqht on
the ground ( The
object of this is to always bring
the vehicle

carry out correct measurements 1.

it is possible to use the free projector.
Secure projector to scuttle panel crossmemher, and
focus it onto a fixed object, which will indicate the
initial positioning of the vehicle.
3. Measure the variation in the wheel alignment wheel
