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 joint at the Power Transfer Unit (PTU)
- U-joints at the center support and pinion flange
- Assembly balanced with traditional balance weights
- Lubed-for-life joints requiring no periodic lubrication

The driveshaft transfers torque from the PTU to the rear axle. It is attached to the PTU flange with a CV joint. The driveshaft is connected by a staked U-joint at the center bearing and attached to the rear pinion flange. 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.
