A truck comprises a main frame having a U-shaped subframe, including a pair of side beams and a forward cross-beam, universally mounted thereon by a ball and socket connection. A rearward end of each side beam is mounted under the main frame of the truck by a suspension cylinder pivotally interconnected therebetween. A drive motor is mounted on each of the side beams and has an output shaft thereof drivingly connected to at least one roadwheel, rotatably mounted on a spindle secured to a rearward end of each side beam. A rearward cross-beam is preferably secured between the rearward ends of the side beams in axial alignment with the spindles.
