Driveline System

WARNING: This page is about a different car, the 2009 Mercury Sable, 2009 Ford Taurus X, and 2009 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.

The driveline system consists of the following components:

Center support bearing
Driveshaft assembly
Front halfshafts
Rear halfshafts
Active Torque Coupling (ATC)/rear axle

On Front Wheel Drive (FWD) vehicles, the transaxle transmits power from the engine to the halfshafts.

On All-Wheel Drive (AWD) vehicles, power is transmitted from the engine through the transaxle to the Power Transfer Unit (PTU). The PTU transfers engine power from the transaxle to the front halfshafts, and through the driveshaft to the ATC/rear axle and halfshafts. For information on the transfer case, refer to TRANSFER CASE - POWER TRANSFER UNIT (PTU) article.

The engine angle is built into the engine mounts. If the engine angle is out of specification, the engine mounts must be inspected for damage. Refer to the appropriate Engine article for the procedure.
