Abstract: A motor vehicle steering system is disclosed. The system includes a steering spindle consisting of spindle members which are non-rotatably connected to one another. One end of a spindle member has a spline shaft profile and is introduced into a sleeve-like intermediate piece which is arranged on the other spindle member and, on the inner periphery, has a negative-shaped spline shaft profile with respect to the spline shaft profile such that the spindle member is plug-connected to the intermediate piece. In order for the spindle members to be able to be connected to each other with minimal effort even in the event of visual inaccessibility, a circumferential guide contour pointing toward the intermediate piece is formed on the spindle member. The guide contour is upstream of the spline shaft profile toward the intermediate piece and is perforated by grooves of the spline shaft profile to form convex guide segments.
