Pic. 3.96. Cardan shaft assembly: 1 - front propeller shaft; 2 - rear propeller shaft; 3 - CV joint with length compensator (DOJ) assembled; 4 - flange fork; 5 - stopper; 6 - intermediate support assembly; 7 - universal joint assembly
Withdrawal
Pic. 3.97. Mounting marks
After aligning the relative position of the propeller shaft flange and the differential drive gear flange, remove the propeller shaft (pic. 3.97).
Note. Remove the cardan shaft in a straight and horizontal plane so as not to damage the protective cover on the edge of the metal part of the cover. Damage to the protective cover can be prevented and the removal operation can be facilitated by inserting a piece of cloth or the like into the constriction of the protective cover.

Examination
Check the driveshaft yokes for wear, deformation or cracks.
Check propshaft tube for kink (beat), deformation and twisting.
Pic. 3.99. Checking the smoothness of movement of cardan joints
Check the smoothness of movement of cardan joints in all planes (pic. 3.99).
Check up smoothness of rotation of the bearing of an intermediate support of a cardan shaft.
Check the rubber fastening elements of the propeller shaft intermediate support for damage and deterioration.
Check the flange for damage and deterioration.
Pic. 3.100. Checking the cardan shaft runout
Check driveshaft runout with dial indicator (pic. 3.100).
Limit value: 0.5 mm.
Installation
Pic. 3.101. Place of application of Samzka
Apply grease to the center of the flange (pic. 3.101).
Recommended lubricant: ALVANIA EP#2 (8–10 grams).
Lightly insert the center of the flange into the differential drive gear.
Pic. 3.102. Installing the cardan shaft
Note. Straighten the driveshaft for assembly. Support intermediate support assembly (pic. 3.102).
Pic. 3.103. Installing the intermediate support mounting bracket
Temporarily install the intermediate support mounting bracket (pic. 3.103).
Note. Install the intermediate support mounting bracket so that the alignment mark «R» was directed towards the rear of the vehicle.
Pic. 3.104. Flange Installation Diagram
Install the flange so that the marks are directed upwards as shown in Figure 3.104.
Align the alignment marks of the relative position of the propeller shaft flange and the differential drive gear flange. Install the cardan shaft.
Tighten the intermediate support mounting bracket to the specified torque.
Tightening torque: 40–50 Nm.
