This was the last year for the old dropout axles. In the light truck line, the H-052 (5,200-pound GAW) and H-072 (7,200-pound GAW) were offered. The “H” stood for hypoid, which was an important distinction when this axle debuted in the late ’40s. Some of the design features of this axle, including the removable pinion carrier with three pinion bearings, one at the nose of the pinion gear, was used for the now legendary 10.50-inch 14-bolt when it appeared in 1973. The traction aid offered for this axle was none other than a Detroit No-Spin, aka the Detroit Locker. The -052 and -072 centersections were identical, except sometimes for ratios, but the housings were different according to the axle weight rating.
