Light Duty Truck Rear Axle Identification

Chevrolet Light Duty Trucks use either Chevrolet, Dana or Rockwell produced rear axle assemblies. See examples of production codes below.


CHEVROLET AXLE


EXAMPLE:

Axle Code Source Code Day Code Shift Code

C = Buffalo Jan. 1 = 001 1st Shift

DANA AXLE

The Chevrolet produced axles use a prefix code stamped into the axle tube for axle code identification. Dana produced axles use the same prefix code as the Chevrolet axles, but they display these codes on a strip of tape attached to the outboard end of the axle tube.
