Fig. 1 (Part 2 Of 2):

The Dodge Viper is equipped with an independent, all aluminum Dana Model 44 (226 RIA) rear axle assembly (Fig. 1).

The 226 Rear Independent-design Aluminum (RIA) axle consists of a hypoid ring and pinion, and a Trac-Lok differential assembly housed within a two piece aluminum center casting (differential housing). The differential cover contains two integrated mounting brackets which allow fastening of the assembly to the vehicle frame.

The pinion gear is of a hypoid design, and is supported in the axle housing by two tapered roller bearings.

The ring gear is of a hypoid design, is in mesh with the pinion gear, and is fastened to the differential case.

The differential case is a one-piece Trac-Lok design. The differential consists of a pinion shaft, pinion and side gears, and a pair of limited slip friction style clutch packs. The differential case is supported in the housing by two bearings located on either side of the case.

Vehicle Storage/Prolonged Non-Operation
If the vehicle has not been operated on a regular basis, it is recommended that the drivetrain be rotated. This should be done at least once every two weeks. The vehicle should be moved far enough to cause the drivetrain components to make several complete revolutions. This procedure will help assure that all internal components receive adequate amounts of lubrication. This will reduce deterioration caused by an undesirable environment (e.g. high humidity).

OPERATION
The axle receives power from the transmission through the propeller shaft. The propeller shaft is connected to the pinion gear, which rotates the differential through the gear mesh with the ring gear bolted to the differential case. The engine power is transmitted to the axle shafts through the pinion mate and side gears. The side gears are splined to the axle shafts.
