For sealing the steering column opening in a body panel located between passenger cell and engine compartment, an assembly consists of at least one steering column mounting bearing, at least one body panel flange and at least one elastomer suspension, via which the steering column mounting bearing is suspended from the body panel flange. The body panel flange is expanded housing-like into at least one series-specifically designed reducing piece, the elastomer suspension being at least partially embodied as a series-independent universal suspension. At least two damping chambers located between the reducing piece and the steering column mounting bearing are formed with the elastomer suspension.
