A washer element for a wheel bolt and/or a wheel nut of a motor vehicle wheel is mounted with one end partially in a rounded cavity of a mounting hole for the wheel and the wheel bolt is supported on the other end of the element. The washer element consists of a sleeve part with an end area formed so that it is rounded, whereby in cross section the sleeve part itself has a profiled wall with a sleeve expansion and/or a sleeve contraction.

A subframe for a motor vehicle has two side plates which extend in the longitudinal direction of the vehicle, are connected with one another by cross members and have bearings for control arms of wheel suspension links, this subframe unit being connected with the vehicle body. The side plates are each formed of a torsion-proof and rigid lattice frame which extends in a vertical longitudinal plane of the vehicle. Between the side plates, torsion-proof cross members are held which can each be screwed on separately in a detachable manner. Together with the side plates, these cross members form a rigid assembly unit which comprises integrated bearings for control arms of wheel suspension links in the side plates. By way of one bearing respectively, which is arranged in spaced horizontal planes in a top and bottom chord of the side plate, the subframe unit is detachably fastened on the vehicle body.

A guiding link bearing arrangement for a wheel suspension of a motor vehicle has an elastic link bearing that is supported at a carrier of the body structure of the vehicle. This link bearing is held at the free lower end of a supporting arm extending in a vertical plane and is fastened at walls of the carrier that are separated a distance from one another.
