A trailing arm suspension is formed as a one-piece stamped body having a central web and two laterally spaced side walls. A wrap is to be secured to an axle and received in a recess between the walls. The integrated wrap has radially outwardly extending ledges which are welded to the walls, and which provide support surfaces along the axle axis. In further features, closing plates are mounted to the spaced side walls.
