TORQUE SPECIFICATIONS

Note. All driveshaft assemblies are balanced. If undercoating the vehicle, protect the driveshaft to prevent overspray of any undercoating material.

The driveshaft transfers torque from the power transfer unit (PTU) to the rear axle. It is attached to the PTU flange with a constant velocity (CV) joint. The 2-piece shaft is connected by a staked U-joint located rearward of the driveshaft center bearing and attached to the rear drive unit (RDU) at the active torque coupling. 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.

The driveshaft assembly consists of the following

  1. Rubber isolated center support bearing
  2. CV joints at each end of the shaft
  3. U-joint at the center support
  4. Assembly balanced with traditional balance weights
  5. Lubed for life joints requiring no periodic lubrication
  6. Unique bolt and washer assembly for the rear CV joint
