In a process for manufacturing a vehicle body shell, the linking of an integral support to a forward structure of a known vehicle body shell may lead to tolerances which require readjustments of the axle geometry of the front axle. Accordingly, the bearing points of each wheel installation unit for the upper transverse control arm bearing which are situated behind one another in the longitudinal direction of the vehicle are brought to a defined distance range by a tensioning of the wheel installation unit, and a center fixation of the forward structure takes place relative to the longitudinal direction of the vehicle.
