Information:
Upon release of the Dana Series 172 and 175 axles, the lubricant drain hole/plug was incorporated into the carrier
of the axle assembly, see Figure 1. Dana eliminated the bottom drain hole/plug in the axle housing bowl to avoid a
potential leak path.
The axle housing incorporates a large high-powered magnet to prevent metallic wear particles from flowing within
the axle system.
Drain the lubricant from a Dana Series 172 or 175 axle using the drain hole/plug located in the carrier of the axle
assembly.
Drain plug torque: 250 ± 15 ft. lbs.
