For axle identification, refer to General Information & Maintenance .


The easiest way to ascertain whether your vehicle is equipped with a Banjo type or a Salisbury type rear axle is to look at the rear of the differential housing. If the differential housing has a rear cover, then it is a Salisbury type; if your housing has no rear cover, it is the Banjo type. Banjo type axles have removable differential case assemblies, whereas the Salisbury types do not.

Banjo Type

The rear axle assembly is of the semi-floating type in which the vehicle weight is carried on the axle housing. The center line of the pinion gear is below the center line of the ring gear (hypoid drive).

All parts necessary to transmit power from the propeller shaft to the rear wheels are enclosed in a Banjo type axle housing.

The 8.7 inch ring gear rear axle uses a conventional ring and pinion gear set to transmit the driving force of the engine to the rear wheels. This gear set transfers the driving force at a 90 degree angle from the propeller shaft to the driveshafts.

The axle shafts are supported at the wheel end of the shaft by roller bearings.

The pinion gear is supported by 2 tapered roller bearings. The pinion depth is set by a shim pack located between the gear end of the pinion and the roller bearing that is pressed onto the pinion. The pinion bearing preload is set by crushing a collapsible spacer between the bearings in the axle housing.

Salisbury Type

Two types of rear axles are used: The standard and the locking. The axle is of a semi-floating type, where the vehicle weight is carried on the axle housing. It is designed for use with an open driveline and fiberglass leaf springs. All of the power transmitting parts are enclosed in a Salisbury type axle (a carrier casting with pressed tubes, welded into the carrier). A removable cover at the rear of the housing, allows the axle to be serviced without removing the entire assembly from the vehicle.

The locking rear axle, equipped with a speed sensitive, multi-disc clutch pack mechanism, locks both wheels together if either wheel spins excessively during slow vehicle operation.

The rear axle identification number is located on the front, right side of the axle tube. See the Rear Axle information in General Information & Maintenance for more information on determining the axle ratio, differential type, manufacturer and date built, from the letter codes.
