Removing
1. Apply alignment marks to the flanges of the driveshaft yokes, the connecting flanges of the final drive and transfer case.
Attention: Mark with paint.
2. Loosen the fixing nuts of the center bearing brackets.
Attention: Do not unscrew the nuts completely.
3. Unscrew the fixing nuts and bolts from the connecting flanges of the cardan shaft, transfer case and final drive. Loosen the fixing nuts of the center bearing brackets. Then remove the propeller shaft from the vehicle.
Attention: When removing, installing or carrying the propeller shaft, the boot of the constant velocity joint can be damaged (SHRUS). To protect the cover from breakage, wrap the area where the cover contacts metal parts with cloth or rubber.
Examination
1. Having fixed the fork on one side, as shown in the figure, check the axial play of the hinge. If the play is out of specification, replace the propeller shaft assembly.
- Limit play: 0 mm
2. Check if the cardan shaft is bent or damaged. If damage is found, replace the propeller shaft assembly.
3. Check for unusual bearing noise and damage. If abnormal noise or damage is found, replace the driveshaft assembly.
Attention:
Central bearings (front and rear) not subject to disassembly.
Hinges are not subject to disassembly.
Installation
Installation is carried out in the reverse order of removal, taking into account the following.
Align the marks made on the cardan shaft before removal, and tighten the fixing nuts to the required torque.
Adjust the position of the bearing brackets to avoid displacement of the insulator in the longitudinal direction.
When tightening the bolts and nuts, do not insert the wrench into the joint.
After assembly, carry out a road test and check the runout of the propeller shaft. If a run is detected, separate the cardan shaft from the final drive. Secure the connecting flange by turning it 90°, 180°or 270°. Then re-road test and check driveshaft runout at each position.
