Removing
1. Shift the transmission to neutral and release the parking brake.
2. Remove main muffler and front exhaust pipe.
3. Put alignment marks on the connecting flanges of the cardan shaft and the rear final drive.
Attention. Use paint to apply alignment marks. It is forbidden to damage the surface of the flanges by punching, sawing, etc.
4. Loosen the center bearing mounting bracket nuts.
Note. The arrow in the figure points to the front of the car.
Attention. Do not loosen nuts completely.
5. To turn away bolts and nuts of fastening of a cardan shaft.
6. To turn away nuts of fastening of an arm of the central bearing.
7. Remove cardan shaft assembly.
Attention. If the CV joint is bent during removal, installation, or transport, its boot may be damaged. Wrap the insertion area of the dust boot into the metal part with rags or rubber to protect the dust boot from damage.
8. Remove clips and remove upper and lower center bearing mounting brackets.
Installation
Installation is carried out in the reverse order of removal, taking into account the following:
Install the upper mounting bracket for the center bearing (1) so that the label is in the form (A) was directed forward.
 |  |
Adjust the position of the center bearing mounting brackets (1 and 2), by moving them back and forth to prevent play in the axial direction of the center bearing insulator (3). Install mounting bracket (upper/lower) center bearing for the car.
When installing the cardan shaft, align the alignment marks made on the connecting flanges during removal.
For proper installation, it is necessary to adjust the position of the mounting bracket front and rear to ensure no deformation (front-rear direction of the car) center bearing insulator.
After installation, make a test drive to check for vibrations of the driveshaft. If there are vibrations, disconnect the cardan shaft from the final drive. Reinstall the propeller shaft by turning it 90 degrees, then repeat the test drive. If vibrations are still present, repeat the driveshaft rotation by 90 degrees until it is rotated by 270 degrees.
After tightening the bolts and nuts to the specified tightening torques, make sure that the bolts (3) on the flange side are tightened as shown.
1. Main gear assembly.
2. Cardan shaft assembly.
3. Bolt.
If the propeller shaft assembly or rear final drive assembly is replaced with new ones, connect them as follows:
Position of connecting flange of final drive (1) label (A) up. Connect the cardan shaft to the final drive so that the alignment mark (IN) cardan shaft (2) located as close as possible to the installation mark (WITH) connecting flange of the main gear.
While pressing the cardan shaft, simultaneously tighten the connecting bolts and nuts of the cardan shaft and final drive to the specified tightening torque.
