A vehicle frame having first and second sub-assemblies permits the rear axle housing to be mounted above the frame and lowers the center of gravity of the vehicle to improve stability on slopes. Connections at two telescoping joints and a cross bar structure provide for quick and easy assembly or separation of the sub-assemblies so that maintenance and/or exchange of the axle unit can be carried out. A single pivotal connection between the axle unit and rear sub-assembly facilitates rocking movement of the axle unit on uneven ground and simplifies installation or removal of the axle unit.
