Abstract
A drive axle system can be converted between a single drive tandem axle arrangement including a rear drive axle a dual drive tandem axle arrangement. A forward bowl is provided for a forward axle system. One of a geared forward carrier and an ungeared forward carrier is mounted on the forward bowl, depending upon whether a dual drive or a single drive tandem axle arrangement is desired. To convert to the other type of tandem axle arrangement, the one of the geared forward carrier and the ungeared forward carrier is removed from the forward bowl and replaced, with the other one of the geared forward carrier and the ungeared forward carrier.
