Buick Enclave: Description and Operation

TRANSFER CASE DESCRIPTION AND OPERATION

Buick Enclave. Transfer Case - Getrag 790
Fig. 46: Identifying Transfer Case

The transfer case in this vehicle consists of an aluminum housing with input helical gear, output driven helical gear, ring and pinion hypoid gear set and an intermediate drive shaft.

The transfer case transfers torque/power to the on-demand rear differential through a prop shaft assembly.

The on-demand rear differential distributes variable torque/power to the rear wheels through individual axle shafts.

Within the rear differential assembly is an active on-demand coupling system.

The on-demand system rear differential control module monitors wheel speed, vehicle speed, wheel slippage and other variables. The module directs the rear differential to distribute torque to the rear wheels as required.

Typical conditions when torque is applied are during vehicle launches, even without wheel slip and when there is front wheel slippage relative to the rear wheels. The amount of torque depends on the vehicle speed and the amount of wheel slippage.
