A trunnion suspension arrangement for a vehicle featuring a pair of generally parallel frame rails, such as a transport trailer, includes, for each frame rail, a trailing beam with a leading portion and a trailing portion. A hanger is attached to the frame rail and the leading portion of the trailing beam is pivotally connected to the hanger by a spherical bearing. An air spring and a shock absorber are connected between the trailing portion of the trailing beam and the frame rail. An axle is connected to the trailing beam between the hanger and the air spring. A bumper featuring arcuate side members is attached to the trailing portion of the trailing beam so that it partially surrounds the air spring. A cage, which is connected to the frame rail, surrounds the bumper and features slide pads that are engaged by the arcuate side members of the bumper to limit transverse horizontal travel of the trailing portion of the trailing beam.
