NOTE: The late 1932 axle shaft was announced in the June 1932 Service News. The
early axle was discontinued and all production and replacement were switched to the
late axle. 1925-1932 axle shafts can be interchanged by matching the nut, hub, wheel
bearing and differential side gears to the axle shaft, and by modifying the grease
seal. The outside diameter of the side gears and the wheel bearing is the same for
all.

NOTE: 1933 and later have a flanged end for the wheel. No removable hub.
On 1938 axles the ring groove for the axle lock is 0.235" from the inside end of the
axle.
On 1939-1940 this distance is 0.266".
1933-1936 STD and 1937-1941 axles have an inner wheel bearing race pressed onto the
shaft. When the bearing surface on 1942-1954 axles becomes rough, the shaft can be
machined to accept this same race.
See group 5.855 part # 111 120.
