12664-1R
Before carrying out repairs to the bodywork of a car, even if the damage seems slight, it is necessary to carry
out a series of tests :
•
VISUAL INSPECTION
This inspection involves the examination of the sub-frame of the vehicle where mechanical components
are mounted and in the crumple zones or vulnerable areas in order to detect folds where materials have
been deformed.
•
INSPECTION USING TRAMMEL GAUGE
The visual inspection may be completed using a trammel gauge which will allow measurement of certain
deformations by symmetrical comparisons (for more detail on each point to check, refer to the repair
bench paragraph below).
•
INSPECTION OF AXLE ASSEMBLY GEOMETRY
It is the only check which determines whether the impact suffered by the vehicle has or has not affected
its road holding.
Important : In borderline cases, it is essential not to neglect checking the axle assembly components which
may also have been subject to deformation.
On principle, no welded component in the body shell may be replaced without ensuring that the sub-
frame was not affected by the impact.

The bracket rests against the rear section of the
side member and is centred in the sub-frame
mounting hole.
NOTE :
- on the left hand side, the hole is round,

The bracket covers the sub-frame mounting bolt
and rests against the mounting bolt washer.
NOTE : The two sides are not symmetrical, on the
right hand side the mounting is set on the rubber
mounting.
If the rear of the vehicle is being rebuilt, these
two points alone may be used to align and sup-
port the front of the vehicle.
