This marking shows the area in which it is possible to
make a partial replacement.
III - ASSEMBLY INSTRUCTIONS FOR A PARTIAL
REPLACEMENT
Only the connections which are specific to the partial
replacement by cutting are indicated.
If there are other issues regarding access to mating fa-
ces, the various replacement options are described in
the basic instructions for structural bodywork repair
(see MR 400). IMPORTANT
Use a repair bench to ensure the positioning of the
points and the geometr y of the axle assemblies.
