1. Method for the installation of a pretensioned roller bearing assembly in a wheel carrier, the assembly comprising a hollow shaft having a shoulder, first and second roller bearings, and a shaft nut, wherein the method comprises:

  • placing the first roller bearing against the shoulder of the hollow shaft;

    installing the hollow shaft having the first roller bearing into the wheel carrier, such that the fist roller bearing opposite the shoulder of the hollow shaft abuts a first surface of the wheel carrier;

    placing the second roller bearing onto the hollow shaft, such that the second roller bearing abuts a second surface of the wheel carrier;

    placing the shaft nut onto the hollow shaft, such that the shaft nut abuts the second roller bearing;

    placing an installation apparatus having, a measurement probe and a stop member, so that the measurement probe lies against an internal stop of the hollow shaft, and the stop member abuts an outer end of the hollow shaft;

    tightening the shaft nut against the second roller bearing;

    determining the axial shift of the measurement probe with respect to the stop member; and

    using a torque wrench to determine the applied torque when the shaft nut is tightened while measuring the change of distance between the stop member and a predetermined reference stop, which permits a differentiation between the actual tensioning process of the roller bearing and the previous process to tighten the shaft nut.
