Abstract: The assembly includes: a front face; a structural front portion (4); a fender front portion (5); a flexible beam (43); and a headlight unit fastened to said beam (43). It further comprises: a centering and guide part (71) fastened to the structural front portion, in a position that can be adjusted, during assembly, along three axes (X, Y, Z); fastening and centering means (83, 85) for fastening the end (43B) of the beam to said part (71) and for centering it thereon; and guide means (93, 95) for guiding the fender front portion (5) on said part (71), providing a sliding connection slidable along one of the three axes (X), making relative adjustment movements possible in order to absorb deformation in said fender front portion. The invention is also relates to a motor vehicle including such an assembly.

Abstract: The assembly includes a front face, a bumper skin, two flexible brackets, and two light units, each of which is rigidly secured to a corresponding bracket. The assembly further includes pre-positioning and guide elements adapted to provide pre-positioning that allows a first end of each of the brackets to move in a substantially axial direction relative to the front face, the elements including members for driving the first end in axial translation relative to the front face, the members operating by meshing, and elements for releasably receiving an adjustment tool in a meshing position. An adjustment tool, and a method of assembling and mounting such a front unit assembly are also disclosed.
