Description
The front and rear propeller shafts have universal joints (not providing equal angular velocities) with needle roller bearings. The outer rings of the bearings are packed with grease during assembly, and a grease nipple is provided for servicing purposes (see the section on maintenance).
Both shafts have ball grooves to accommodate the different distances between the axles and the gearbox. The splines are packed with grease and protected by a rubber boot.
NOTE: This joint does not require lubrication.
The front and rear propeller shafts are "phased", equipped with joints at both ends, A and B are spaced apart as shown in the figure.
Phasing is necessary to increase angular changes. When assembling, it is necessary to correctly align the cardan shafts.

Vibration magnitude
Make sure the universal joints on the driveshaft are not seized or worn; to do this, check them for increased radial and axial play. To perform this operation, insert a suitable lever into the joint and check the movement. When both shafts are in satisfactory condition, but vibration is still present, the operation of the transfer case and wheel balancing should be checked.
