Install

It is essential to observe the tightening procedure for the bolts (1 to 6) securing the front propeller shaft to the front axle transmission and to the transfer case.

Noise and vibrations can otherwise be produced at high speeds.

The bolts (1 to 6) securing the propeller shaft to the front axle transmission and to the transfer case must always be replaced with new ones.
Align markings and move to 12 o'clock position.
Tighten bolt (1) to initial torque of 10 Nm and make marking.
Tighten bolt (2) with specified torque and mark.
To do so, turn the propeller shaft by 180°.
Tighten remaining bolts in the sequence 3-4-1-5-6 with the specified torque.
