Abstract
A pick-up truck vehicle is provided with an elevatable cargo box to facilitate cargo loading and unloading. The vehicle includes a U-shaped cargo area within which the cargo box is located, thereby requiring removal of all suspension assemblies to the outer sides of the vehicle to permit the cargo box to be movable between elevated and lowered positions. The side-mounted suspension assembly employs a leaf spring coupled to a pivoting wheel carrier. A pair of integrally formed longitudinal members couple the wheel carrier pivotally to the frame, and a transverse, upwardly directed arm is pivotally coupled to the leaf spring by a dual pivot arrangement. Pivoting action therefore is present relative to the frame and the leaf spring. The wheel carrier is integrally formed with the longitudinal members and the upwardly directed arm and is disposed beneath the leaf spring.
