Flex AWD V6-3.5L (2009)
Drive/Propeller Shaft: Description and Operation
Driveshaft
NOTE: All driveshaft assemblies are balanced. If undercoating the vehicle, protect the driveshaft to prevent overspray of any undercoating material.
The driveshaft assembly consists of the following:
-
Rubber isolated center support bearings
-
CV joints at each end of the shaft
-
U-joints at the center supports
-
Assembly balanced with traditional balance weights
-
Lubed for life joints requiring no periodic lubrication
-
Unique bolt and washer assembly for the rear CV joint
The driveshaft transfers torque from the Power Transfer Unit (PTU) ) to the rear axle. It is attached to the PTU flange with a CV joint. The 3-piece shaft
is connected by staked U-joints located between the center bearings and attached to the Rear Drive Unit (RDU) at the Active Torque Coupling (ATC).
The driveshaft joints allow the smooth continuous rotation of the driveshaft through the allowable angle planes and length variations required in normal
vehicle operation. The driveshaft is always turning at front wheel speed. The driveshaft is not serviceable. A new driveshaft must be installed if worn or
damaged.
