Trucks Aren’t the only Vehicles with 4-Wheel Drive
In this article we look at the BorgWarner 4476 and 4479 transfer cases, which are all-wheel-drive units. All-wheel drive signifies that the car has the ability to send power to all four wheels all the time with no driver controls. These transfer cases are essentially the same unit with some subtle differences and are found in the Cadillac SRX models. In 2004 all SRX models were equipped with the BW 4476. In 2005 this model was equipped with both the 4476 and 4479, and from 2006 through 2009 all were equipped with 4479 units.
