What are some tips for Chevrolet axle identification?


Quick Answer

Identify Chevrolet axles by casting numbers, production code identification, physical characteristics of the axle and year, make, model and equipment package of the vehicle. Visual identifying characteristics of a Chevrolet axle include the shape of the differential cover, the number of bolts on the differential cover, whether the axle is an independent front suspension, full-floating or semi-float rear axle, and the size of the ring gear.

Chevrolet vehicles manufactured prior to the mid-1980s have casting numbers that translate to specific information about the axle. The casting numbers are on the axle housing, either on the axle tube or near the center differential. These codes include information such as manufacturing date, manufacturing location, axle size and gear ratio. Websites specializing in older Chevrolet manufacturing codes, such as TheCamaro.com, provide resources to translate the codes.

Chevrolet vehicles manufactured after the mid-1980s typically do not have translatable axle codes or casting numbers. Consider using an axle identification tool such as DiffWizard.com that allows users to input year, make, model and equipment package to return possible axles for those production years. Visual identification markers typically can fully identify the axle with that information. You can determine specific information about the axle, such as gear ratio, traction type and drive ratio from the production codes. Production codes are located in the glove box or driver's door jamb, and codes beginning with the letters F, G and H pertain to the axles.
