Introduction
Dana Corporation, presents this publication to aid in maintenance and overhaul of Dana tandem drive axles. Instructions con-
tained herein cover four basic axle models. Their design is common, with differences in load capacity. Capacity variations are
achieved by combining basic differential carrier assemblies in different axle housings, axle shafts and wheel equipment.

Some models (identified with letter “P”) are equipped with a gear-driven pump, designed to provide additional lubrication to the
inter-axle differential and related parts. Instructions contained herein are applicable to all axle models, unless specified otherwise.
For brake information and axle mounting or suspension systems, refer to pertinent truck manufacturer’s literature.

Two design variations of tandem axles are included in this manual. The major difference is in the shaft spline design.
