by a broadcast code on the right axle tube near the carrier. The rear axle
identification and the manufacturer's codes must be known before attempting
to adjust or to repair the axle shafts or the rear axle case assembly.
The rear axle ratio, the differential type, the manufacturer, and the build
date information is stamped on the right axle tube on the forward side.

(C) Buffalo and (K) Canada. |
• | (3) The next 3 digits indicate the day built, displayed in Julian
Date form. |
• | (4) The last digit indicates the shift (1) first and (2) second. |
In order to verify reports made on rear axle assemblies, include the
full code letters and the build date numbers.
